Can this PSU handle Gtx 280s SLI'd?

post #1 of 10
Thread Starter 
I am wondering if this PSU can handle 280s in SLI

http://www.directron.com/s75qbb.html

I know I might just be acting plain stupid, but i need to know if it can or cannot. If not, then what would be one that could under 100 USD? This is for my cousin's rig btw.

One gtx280 is around 230w. With sli scale, assuming a quad cpu, air colling, typical setup, you are looking for somewhere around 630w when OC. That psu can do 60a/720w on 12v so it is fine.

His CPU is an AMD phenom II 955 at stock. the 280s are BFG OC editions.

Yes, a 750W can handle 2 GTX 280s in SLI with room to OC the CPU as well. IIRC, the PSU you're looking at is fine, but there are others such as the TX/HX750, TruePower New 750, EA750, SS-750HT, and I think the Kingwin Lazer 750w is also decent.
