Recently picked up a 560 ti to replace my HD 6770.
The card runs all games fine at near max setting but i crash after 10-20 minutes. It could be a PSU error, but i doubt it as 500W seems enought for this card.
i7 930 (Not OC)
Inno3d 560 ti
500W PSU, cant be bothered to go check brand.
With a rough build using neweggs psu calculator the recommended is ~530, which i think is whats happening for the 560ti i would recommend at least 600w, but maybe I'm wrong.
