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

[Finksy]

Have packages to ship from stock.  I added another package specifically for 2x Antminer S7's called the Double A, due to demand for this specific package.  I think it provides quite a lot of value compared to all other alternatives on the market, including the Bitmain PSU's.

[fortysixntwo]

The "Double A (Antminer/Avalon)" Package - $190
Enough to power 2x Antminer S7's for as cheap as possible
 - 1x 2880W PSU
 - 1x Breakout board
 - 20x 24" PCIe cables
 - 1x C19 cable (specify C19-C20 or C19-NEMA 5-15P)

PMed you

Thanks Finksy

Do you have the 4000 watter ?



https://bitcointalk.org/index.php?topic=1178099.msg12401250#msg12401250


I am thinking of using this with 2 s-7's and an avalon 6  so we are talking


1200 + 1200 + 1000 = 3400 watts


or with an under clock

s-7        S-7     a-6      a-6
1150 + 1150 + 900 + 900 = 4000 watts.

What kind of plugs are on your PDU's?

Not yet Phil, I should be receiving the PCB's to start assembling the boards by the end of this week I hope.  I know there is a lot of interest in it, and I have quite a bit tied up in materials for it so I am as anxious as you to have them available.

What kind of plugs are on your PDU's?

4x C19 plugs, each with 15A breakers and a 50A main.  I can source PDU's in other configurations including 3-phase if requested.

I figured the receptacles were C19 but I was wondering about the input plug for your single phase 50a pdu as there are a few types of 50a plugs.

TIA.

Right sorry, the PDU comes with an L6-50P plug: http://www.stayonline.com/detail.aspx?id=6272

HUBBELL CS8265C Got it thanks.  Can you PM me a quote for four PDU units shipped to Houston, TX?

Hello,

I have PM'd about a custom order.

I had to register here to make my request, I see it added the newbie warning.

Im sure I will be sticking around. My 6 x S7 farm is getting ready to go live 

Thanks

sending pm I need cables  those 15 gauge come to mind

j4bberwock sent me a 2000 x  2 = 4000 watt break out board.

I ordered two psu's on ebay.


 I will need cables

  18    15 gauge
  12    16 gauge

Does anyone know if its possible to change the output voltage on this 2880 psu? What about the bitmains 1600 can you change the output voltage on that PS

[Finksy]

I believe there is a write-up about upping the voltage on Bitmain's 1600W somewhere.  As far as I know, voltage control is not possible with the 2880W PSU's, however the dual DPS-2000 that J4bberwock has developed and I should be producing this week will have voltage control as an option.

Do we have pricing on any of the dual 2000 setups yet?

Not like you can on the DPS-2000BB, however the 2880W PSU does seem to internally adjust voltage based on load to maintain a target of 12V, meaning even under a serious load the PSU will continue to deliver 12V and not dip like you see with most..

if you open bitmaintech's psu it has an internal pot that cranks up to about 12.6  I just read a review with photos of the pot.

The bitmain psu has shitty pcie cables.  and cost over 165 shipped to the usa.

finksy + j4bberwock can supply 15 gauge beast cables this will help over clock and if you have 2 avalon 6's like I do ite becomes more important since the avalon use only 4 jacks.

@ finksy  I sent a pm on ordering the 15 gauge cables.

j4bberrwock sent me a breakout baord and i have 2 2000 watt psu's from ebay coming.

I will need the 15 gauge cables I want to do a series of tests and photos that show how well they work for avalon 6's and I held onto my best s-7 I want to show how the better cables allow higher clocks.

Any update on the 2x 2000W PSU board? Sign me up for 2 boards from your initial batch.

Thanks.
