EPS12V to PCIe via adapters

post #1 of 3
Thread Starter 
Is there any reason I should NOT power a 3rd GPU via my 2nd (unused) EPS12V output? For the purposes of this thread, assume wheatley 4.0 is the rig in question.

I will obviously have to use an adapter to convert the pin layout (I know enough not to hook a 12V+ line to ground). Assume I will not exceed the rated power output of the PSU.

GPU in question is a GTX460 - and the xtreme PSU calc says it'll put me at about 780W, so I'm not worried about overloading the supply's capacity.

It isn't the ideal plan, but should be doable. The pci-e 8 pin has 3 x 12V while the cpuEPS has 4 x 12V (on opposite sides as you know), 12V is 12V & ground is ground so as long as they go to the right places it should at least work.

That's what I'm thinking.

Ideally, they'd have provided an additional set of modular PCIe power cables, and made it either/or (EPS/3rd GPU) plug wise.
