Radeon 6970 PSU? - Page 6

post #51 of 55
If you get just one 6970, then there's plenty of power even though using a 9400GT as PhysX could end up being a performance bottleneck.

I think it's certainly worth trying, but I also think it's important to compare the difference in performance both with and without the 9400 GT.

I don't plan to use it for CF, I plan to upgrade to a higher wattage.
Do I need to use a $10 no brand PSU from Bestbuy to know it's garbage? Just because it "works" for you, it doesn't mean it's good. Poor electrical performance almost never causes immediate damage - it's usually a gradual effect.

Anyway, the GX650 (Seventeam OEM) is realistically a mediocre ~550w unit, as that's the best it can do without the ripple going out of spec on the minor rails. The build quality is also pretty poor. I'm not too certain on how the Enhance OEM GX650 performs, though.

Then that doesn't affect me. I don't need anything near 550w.
