850W PSU for GTX285 SLI + GTX 260 PhysX?

post #1 of 6
Thread Starter 
Basically all I want to know is if I can add another GTX 285 to my system and keep my current 260 for Physx without getting a 1kW PSU

With the GPU's at stock I should be right around 688W, but that sounds lower than it should.

Opinions please

EDIT: For clarity, this will be SLI GTX285 + GTX 260

Yeah you'll be fine as long as it has enough PCIe connectors (or you have Adapters)

you will be good as long as you have the right amount of pcie 6 pin connectors.

DO NOT use those adapters as a long term solution.


ps. I was told on my 850W that I can run two 480's on it. (they use more power vs 580's)
So you will be good. I recommend SeaSonic.
One of their units just went platinum efficiency also =]

BUY MY 285 2GB WITH ACCELERO COOLER.

GTX285 and GTX260 are between 180w and 185w. GTX260 draws less in Physx. I think the number around 700w (Phenom @3.9) is about right. That 850 unit can pull 70a/840w on 12v so it should be fine.
