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

J'observe qu'il y a plusieurs Québécois sur se forum. Mon Francais est au niveau primaire mais je peux communiquer sans probleme.

Me gusta mucho aprender español, y tengo un conocimiento muy básico (con traductores). Pruebame, si eres paciente

Here is my PGP key for anyone wishing to send their personal information encrypted:


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.

are the 24" standard 16 AWG cables pci to pci or pci to bare wire?

He isn't doubling the price, those prices are only for my classic boards (Common Slot, HP DL580G3 and DPS2000-BB)
The pricing for the 2880w boards can be found here:

He is reselling at the exact same price you'd get from me, but you will have faster and cheaper delivery.

I figured I was missing something. Thanks for clarifying

Is there anyone UK based doing this?

I'm based in France, so I'm handling all european orders directly.
Since the first batch is sold out, I'll probably won't take orders until mid-march.

Take my money!!

and pm'd you back. hook me up

Just convince your significant other that drying clothes by air is way more eco-conscious! Then start burning 30A of 240V 24/7 on increasingly difficult mathematical algorithms.

You can use the dryer outlet or the stove outlet if you are not using those currently.

110V-120V is just not enough to run large PSU's, the required amperage would be crazy.
