[2 is fine, still only about 165W per PCI-E.

So each of the 9 hash boards draws about 330 watts apiece?

So the remaining 500-sh watts is for the fans and the controller?

Itll be about 90W for the fans, 20W for the controller and the rest is PSU inefficiency. I calculated with 90% PSU efficiency so at 93 it makes it 170W per PCI-E when using 2 a board.

Do you think it's going to work at 90% efficiency with their own PSU power supply APW3-12-1600-B2 https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694  (Note they claim 93.8% efficiency)

Or is that thing just a POS under normal working conditions and we should stick to normal computer PSUs?

I'm guessing you are wanting to hid from 1 activity.  But when looking at watts this high going from ATX to server psu's can save you a lot.

Someone can go out there and compare.  But unless there is a big deal/bargain on a good ATX server PSU's win on price anymore.
