A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches.

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Faqs about these systems


~

Q: ddr4 is expensive what do I do!
A: good news! you can run the cache on the cpus in flat mode and you do longer need ram. this is not a joke my server
running right now has empty dimms.

Q: why the excitement?
A: the intel s7200ap is the only motherboard available outside of a prebuild system for the x200 intel phis

Q: I hate computers but like these what should I do
A: Buy a full h2000g chassis and 4 compute modules. it will be plug and play.

Q: but does windows like them?
A: in typical windows fashion of hating everything that is cool, not so much. I got it to work in windows when I disabled
hyperthreading and im still testing. linux worked flawlessly. Edit: if you disable 4 cores they will work with hperthreading
enabled

Q: how do I control my raging boner?
A: Embrace it and if it doesn't die down in 4 hours consult a doctor.

Q: WHY DO I NEED THIS!
A: It can mine :P (2700h/s on monero on only 200w)


Q: how do I give you monies
A: I take anything of value including crypto, cash, the corpse of a x99 rig your parting with as a result of this intel bug, ect...

IBM 2880W PSU/Breakout Boards - *NEW* Package deals for T9/S9 & A7

Please see here for IBM 4K PSU packages: https://bitcointalk.org/index.php?topic=1308296
Please see here for GPU rig powering packages with all adapters necessary to run rigs off these PSU's! https://bitcointalk.org/index.php?topic=1864539
NEW - PACKAGE DEALS
The "Get Me Going" Package

The "Double A (AntmineAvalon)" Package
Enough to power 2x Antminer S9's for as cheap as possible - 1x 2880W PSU - 1x Breakout board - 20x 24" PCIe cables - 1x C19 power cable of choice (see below for stock)
The "Royale With Cheese" Package
(Perfect to run 2x Antminer S9's, mixing and matching lengths for flexibility and value.) - 1x 2880W PSU - 1x Breakout board - 11x 24" PCIe cables - 11x 36" Deluxe PCIe cables - 1x C19 power cable of choice (see below for stock)
The "Pimp Daddy" Package (Add a 50A circuit and go big, with PDU included for clean, simple & safe install) - 3x 2880W PSU - 3x Breakout boards - 1x 40A 4-port PDU with breakers for each circuit - 30x 24" PCIe cables - 30x 36" Deluxe PCIe cables - 3x C19 power cables of choice (see below for stock)
Boards and cables ship from Canada, PSU's ship domestically in the US to save on shipping and any potential duty/taxes at the border.
Individual pricing Note: Bulk pricing is available, please contact me.
Board price - $65 each.
PSU (Refurbished) - IN STOCK. Includes ground shipping within the US.
I can supply PCI cables in two different configurations:
-36" Deluxe, high quality 16awg made in USA- $4.50 each (IN STOCK)
-24" standard 16 AWG cables - $2.50 each (IN STOCK)
C19 to C20 cable (14awg, 1.6M) - $12 each

24A continuous-rated PDU (requires 30A circuit): $60
60A 3-Phase Delta current-monitored PDU with remote access: $350
LEASING CONTRACTS
I have started to offer leasing packages for use in approved Data Centre/Co-locations. This can be beneficial for many reasons:
-Less upfront capital required, allowing more to be spent on additional mining hardware which can offset much or all of the cost of the lease
-Limits risk and cost of equipment failure, and associated down time due to failures
-Saves shipping costs for heavy PSU's to and from hosting location for duration of your contract
-No equipment depreciation
-Helps eliminate ownership problems associated with Group Buys, when more than 1 member shares purchase price of PSU to host together
-All maintenance, replacement, shipping, setup, and lost revenue from down-time due to PSU failure is my responsibility
Please contact me for details.
Shipping
Shipping will be calculated individually, to make sure you are getting the best rate. All prices are in USD. I am willing to accept escrow through OGNasty, and can also do Paypal but buyer will be responsible for covering costs of either services (4% added to paypal, OG charges 1% for escrow).
Each package of PSU, breakout board & 10x PCI cables is approximately 16 lbs.
The BTC address for all non-escrow breakout board orders is here: 1GWQYCv22cAikgTgT1zFuAmsJ9fFqq9TXf I will not PM you asking for payments to any other address, so beware of F1nksy, Fink5y, or whatever scammy names might pop up.
Original Post:
Hi everyone,
I am the official North American distributor of Break-out boards for the IBM 2880W Bladecenter H PSU's, which are 80+ platinum rated (94%+ efficient) Edit: UN-VERIFIED AT THIS POINT and have provision for 22x PCI-E cables. Unlike other server boards, these don't rely on screw-down terminals and bare wires which can get loose and spark causing fire hazards, and limit the exposure of live contacts to surfaces above and below the PSU. Instead these use a double-sided PCI 6 pin cable, which only cost about $0.10 more than the standard PCI-6 to bare wire versions. Also, unlike the DPS-2000BB -which is the next largest server PSU available for miners- these have fans already built-in, so don't need extra work to set up up and deploy.
The PSU's themselves are available on e-bay and elsewhere (I sell them as well), and the boards will be priced at US $70 $65 each (better pricing for bulk purchase, volume structure will be the same as J4bberwock's). Each PSU can handle 2x Antminer S7's, 3x SP20's, 5 Antminer S5's, or 8 Antminer S3's. You won't find better value for power, and there are very few ATX-based PSU's that provide 80+ platinum efficiency (and none for under $200 for even 700-800 watts). Edit: UN-VERIFIED AT THIS POINT Lastly, unlike ATX-based PSU's, these can be run at (and I have found even over) their rated power, as they were designed that way for server use. They do, however, require 240V input. Also, running these over at over 90% load will give you slightly decreased efficiency, and could affect their reliability.
I have personally taken 3x SP20's to settings around 960 watts (at ports, not at wall) each for approximately 2 weeks, and the PSU drew 13.41 amps (@ 235 volts - 3150 watts @ wall). So at absolute full load (or possibly over), these will still hold over 90% efficiency. Very impressive, and I will be testing different fans to reduce sound for home mining (fans on these PSU's are slightly louder & higher pitched than SP20 fans). Sloopy informed me that he ran 11x Antminer S3's on a PSU for a while (over 3,300W DC!), but that is certainly not recommended, and will eventually cause the PSU to fail. It is simply a testament to how tough these PSU's truly are, and that spikes over their rated output shouldn't affect performance.
Here are some pictures:
Feel free to contact the developer of these boards if you have any concerns, he will verify that I am authorized to sell these. https://bitcointalk.org/index.php?action=profile;u=206446

I will honour a 10-day return/exchange for PSU's or Boards that are DOA. However, these PSU's are used and although I try to briefly load test them all before sending them out, it is impossible to predict failures. As such, no warranty will be offered beyond what was previously mentioned. If you are looking for more peace of mind, please feel free to source PSU's yourself either new or used.

[CANADA-BC] [H] Crypto Currency Mining Enclosure and hardware FULL setup sale [W] $ or Bitcoin

I own a crypto currency mining investment company and I'm selling off the current hardware setup. It has been in use since mid-March of 2014. I've had a series of unfortunate events occur in my personal life that require me to sell off my business's hardware and other personal items.
This is for a firm priced sale, I am looking for a buyer that is either wanting to get into the mining business and wants a GPU based setup that can tackle all the new algorithms VS ASIC based setups that go obsolete within months and have no resale value. Or a buyer that wants to expand their mining farm or mining business and would love a plug-n-play type setup where the only thing they are required to do is have one power feed wired into their warehouse or home panel. This would be for local pickup only most likely. It will require the buyer to have a truck or to rent a u-haul type of moving truck. The system is roughly 60 inches tall by 95 inches long by 24 inches wide, not sure on its weight but moveable if the cards are removed(the cards are designed to be plug-n-play as well, no screws, just pop out pop in.) and runs at 240v for PC hardware and 120v for fans/misc regular appliance plugins(routers/switches etc).
The enclosure houses 8 systems which consist of 46 R9 280x video cards (it has room for expansion), has its own built in surge protection system to withstand lightning and other outside-the-enclosure based surges, whole system runs at 240v for best efficiency, has a 100amp breaker panel which is attached to the enclosure for maximum expansion.
The enclosure has 6x20 inch box fans which provide the 24/7 constant air flow for the video cards. I have two other 20 inch box fans that are for in and out airflow for fresh air circulation. All video cards are easy to access and can easily add or remove cards to/from the unit. I built the enclosure design in-house.
Serious inquiries ONLY, I have priced this as fair market price for used hardware among the enclosure costs which include the power panel, surge protection, cable runs, professional electrical hardware/electrician fees etc. This is a full plug and play type enclosure setup for any mining farm out there. Originally built for $33000~, I'm strictly selling it at a fair hardware priced value with cutting out a lot of the fee's that you would have to pay for an electrician to wire up your own custom enclosure and the electrical hardware. Cash or Bitcoins only.
Asking $15000 Canadian firm. Also I am located around Vancouver, British Columbia, Canada.
