You can disregard what Phil said about the PSU, the 2880W units can run 2x S9's at full clock (any model including the 12.93T) without problem. Whether the miners will last at stock clock I can't say for sure though. The only problem the boards have had is when individual PCI cables are pulling more than 225W without proper cooling on the board, the sockets tend to start browning as Phil's did with his Avalon 6's.
The PSU's rating takes its own fans into account already so that doesn't need to be subtracted, and they will run at 90-100% load all day, every day. There is not a tougher PSU solution on the market than them in my opinion.
Topic: i got PSU: What I miss now??? (Read 850 times)
One more question are you looking to run 2 machine on this ?
if so you will need to lower frequency clocks on the two miners from 600 to 550 or about 10% since I do not know if your miners come set at freq 600
any power from 208 to 260 will work

philip,
i don't understand this..
S9 use about 1172W + 12% at the stock clock (550MHz) for the 12TH/s
with 2880 watt i get about a 280watt reserve...
No???
i'm missing some details??
they will use 2625 watts at stock clock.
the fans are little screaming monsters and will pull 75 watts so you will be at 2700 watt and while your psu is rated at 2880 that is under proper temps and a new unit.
so I would be inclined to drop clock to 500 first two days then bump to 525 next two days. then if all works do 531.25
I did not know who power consumption at the wall, declare here https://www.bitmaintech.com/productDetail.htm?pid=0002016081702344625140A58uNg0630, is without fan consumption!!!
thank you fot the tip!!!
but 75watt for 2 fans right??
3 tiny little screaming fans are in the psu and they will pull 75 watts plus the six boards and 4 fans for the 2 s-9's
so I would be inclined to drop clock to 500 first two days then bump to 525 next two days. then if all works do 531.25
i think, do you do it to check hardware quality and miners stability...
but miners are not certified and tested at the eclared settings, before delivery to buyers???

do you have 240 volt power?
did you get an ac power cord for it?
you are in Italy correct?
J4bberwock is in France

i'm in EU...
we use tipically 220V-240V 50Hz-60Hz
i think is ok
I have attached two links for a source of breakout boards for your IBM 2880 PSU. Both J4bberwok and Finksy are trusted members that support this forum.

Check out the for sale forums - you need the breakout board and the PCI cables, and there are several people who sell on there. Finsky is who I've bought from in the past, but he's in Canada so might not be the best option for you - but I'm sure there's someone actively selling to the EU on there also.

You shouldn't need anything to split PCI cables, the breakout has more outputs than you typically need.

"breakout "

an IBM Bladecenter H Power Supply, 2880W.
i want to use it with S7/S9
but now i need adapter to split in PCI-E 6 pin cables, and cables too?
what kind of adapter I have to buy???
and where can I buy it???
