Power Supply Question?

post #1 of 5
Thread Starter 
I am wondering if 750w is enough to run a XFX 7990 GPU and an AMD FX-8350 CPU? smile.gif

According to this calculator it's overkill but I just want to double check.

This is at stock speeds and from the PSU and not the wall wattages.
FX-8350 (4.0ghz/4.2ghz turbo) Max Out about 180 watts.
HD 7990 Max Out about 568 watts.
Total of 748 watts max.

FX-8350 @ 5.0ghz Max Out about 320 watts
HD7990 Max Out about 568 watts.
Total of 888 watts max.
I would go with a 950 or 1000 watt PSU.
