Hello
Is possible to use APW3-12-1600 , (s7 psu) to power a mining rig (4 X  Sapphire Radeon HD 7970) ?

maybe but not really

you need to understand how to keep the power from the miner psu away from the mobo and a second psu

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Sure as long as the GPU's are using 6-pin PCIe connectors. Many cards are using 8-pin connectors. Beyond that, as long as total power they need is a bit less than the 1600w the Bitmain PSU can supply (ALWAYS give some reserve margin!) yer golden.

He still need a multi GPU setup, since a PC require 4/8 pins for the CPU and 24ATX connector, then the risers need sata/molex, etc. Thus he need to power the risers with the PC's ATX, only then can he use the server PSU to power the GPU's. And he need to power the PSU probably at the same time.

You can split it with an ATX PSU but if the 12V loads are mismatched it will give the motherboard a real hard time.. I do have a setup using the 2880W PSUs I sell with 12 GPU and it works..

Just power the risers with the ATX and the GPU with the Server PSU, power won't cross. (Somehow)

Couldn't he use that Bitmain PSU with a 12VDC PC power supply made for car use?
It would provide power for motherboard etc. and Bitmain PSU for GPUs.

So I mean that the 12VDC PC power supply would be connected to Bitmain PSU's 12VDC

That can work, or you can power the whole lot from the server PSU with a purpose built 12V ATX supply, that is what I do.. The server PSU handes 12V duties for the whole system including motherboard..

sorry to bump an old post...

but is this confirmed to be working safe?

i have 6x asus strix oc rx470's that run on 6 pin pcie, was thinking about running mobo/cpu/ram/ssd/pcie risers off a 650w corsair and powering the gpu's from bitmain apw3+ 1600w (s7 spu) .. just dont want to risk fkn anything.

or would running dual atx be a saver option? as i have a Corsair 1000W RMX sitting idle atm too?

Don't know, but then again this area and specifically this thread is for Bitcoin hardware.
Perhaps try posting in an altcoin area for an answer? Wink
