Just wanted to thank J4bberwock for the 2880W boards, these boards are great. Very easy to go dense with miners with these boards and their well made not a single issue. Thanks again.
Very nice setup, McHouston. I just purchased 3 of these IBM 2880 watt PSU's myself. I'm about to order 3 of these breakout boards and 15 AWG cords. May I ask how many S3's you have hooked up to each 2880 watt PSU? Also, if you purchased PCI-e cords as well, what length cords did you get?

https://bitcointalk.org/index.php?topic=563461 (my own thread) I updated all my pricing today to offer better cables at competitive prices. 6" 18awg splitters (M-F-M) 24" 16awg PCIe-to-PCIe (can handle 300W) 24" 16awg PCIe leads (can handle 300W) these cables should work great with the breakout boards, and 24" (+6" if you use splitters) is sufficient to deliver power to most devices. as a side note: whats the best reccomendation for a quiet server PSU? I found that the DPS2000 could be cooled by a fairly quiet fan, but has thermal shutdown at ~1400W. Would like to find a way to get high-efficiency power at a decent cost and without the shrieking 40mm/60mm fans that most power supplies have. If its louder than a 20% SP20 fan, its not suitable

If its louder than a 20% SP20 fan, its not suitable To meet that need I was using a double stack of DPS-2000BBs with 120mm fans to cool them.. Had no issue running with quieter 120mm fans provided I had a decent amount of space for airflow.. In more restrictive 19" rack setups with shelves I had to push the 120mm more and it would ended up louder than an SP20 at 20%.

Do you run it with fans on one or both sides, and whats the actual CFM of those fans (I have some 75-110 CFM fans that would be nice, but might lack enough airflow for operation past 70% load

My deployments are all at a data center, I don't actually have any here at the house to look at..

very interested in the 2880 and the break out boards. When will you have these? I'd like 5 in Canada ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) Hi everyone, I am the official North American distributor of Break-out boards for the IBM 2880W PSU's, which are 80+ platinum rated (94%+ efficient) and have provision for 22x PCI-E cables. Unlike other server boards, these don't rely on screw-down terminals 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 2880W PSU's are also more efficient than the DPS-2000BB's @ 94% efficiency. The PSU's themselves are available on e-bay and elsewhere (I sell them for $60 each), and the boards will be priced at US $70 each for 25 or less (better pricing for bulk purchase, volume structure will be the same as J4bberwock's). Each PSU can handle 3x SP20's, 5.5 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). 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. 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). Here are some pictures: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi59.tinypic.com%2Fbhhrma.jpg&t=665&c=yWcIvBUF0LCBdg) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi62.tinypic.com%2F2zfr9y1.jpg&t=665&c=SjhmafvC35WmYg) 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 Board price - $70 each. Orders over 20 will follow J4bberwock's future pricing structure PSU (Tested used) - $60 each I can supply PCI cables in two different configurations: -36" copper-wired, high quality 16 AWG cables (J4bberwock's design) - $3.50 each (Waiting on shipment) -24" standard 16 AWG cables - $2.50 each (In stock) -C19 to C20 cables - $12 each Shipping prices will be as follows: CANADA1-10 boards -$10 11-20 boards -$15 USAShipping with tracking (from Canada) 1-3 boards -$15 4-7 boards -$20 8-20 boards -$25 -If you don't need tracking and would prefer just proof of shipment, $5 can be knocked off each price point- Shipping for orders with Cables or PSU's 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. Here is the spec sheet with efficiency rating: http://www-03.ibm.com/systems/bladecenter/hardware/chassis/bladeh/Thank you for your time, Finksy

Very nice setup, McHouston. I just purchased 3 of these IBM 2880 watt PSU's myself. I'm about to order 3 of these breakout boards and 15 AWG cords. May I ask how many S3's you have hooked up to each 2880 watt PSU? Also, if you purchased PCI-e cords as well, what length cords did you get? I put 8 S3's on each PSU, that picture was taken with the prototype boards so they only had 16 connections available. I only use 2 PCI-E cables per S3 and they are able to run at full power and not be in danger of melting the cable. Most are also overclocked to S3+ setting. I would keep it at 8 S3's per PSU even if I put the production 22 port version on that shelf. The wires in the pic are J4bber 36", I choose to use all 36" as the voltage drop was not that much since they are a good gauge and copper. These PSU's are beasts they will take an insane amount of heat. In the pic you actually see the intake for the PSU facing the same side as the exhaust from the S3's. So the PSU is sucking in hot S3 exhaust and having no issues. (I have redone this)

Hi I'm new so sorry for stupid questions.
I have 1 x s3, 1 x a2 mini terminator and 2 x Zeus Lightning both that in their own take 1000w psus.
I'm wondering what I could use to power these instead of psus bought from the store, can your products help and if so what would I need?
Also if so - how noisy and how much heat would these be producing - would I be best of placing everything in the garage?
Cheers
Ps I'm in Australia so if can be done, what would shipping be to Melbourne?

please give me your legitimate mail that I could write to you. ? thank you. Good afternoon. I just went to the post office in France and considered sending 1kg load here is the link http://www.colissimo.fr/particuliers/envoyer_un_colis/preparer_un_colis/Essentiel_pour_envoi_du_colis.jsp service received a total of EUR 25, where you can arrange everything at home and bring the finished sending mail, it's more for a 5% discount can be even cheaper if you send it Petit paquet. I decided to buy a sample until three boards the old model with screw connection, they will not be heated if I plug the power 1900watt ........ unfortunately I have already bought 6pin wires. On the other hand conventional terminals. I therefore suitable only for the old design vintah.spasibo await your decision with mail?! if you can do me a delivery within 20 to 25 euros by all means send 3 cards on palpay

hello! I do not quite understand how much you have to pay 127 dollars or 117 ?! my translator does not translate half the words) and what do you want me to pay for BTC.? how much is Bitcoin? why not pay palpay better it otherwise I will have to buy Bitcoins?!?!?!
