Will my OCZ modstream 520w handle a 7900GTX? I have A usb keyboard, a usb mouse, a usb lighted mouse pad... also connected, along with a cd/dvd drive, dvd burner, amd 3700+, and 2 gb of ram... and a Audigy ZS 2 sound card.. Oh, and four 80 mm case fans. I think it will do it..

Thank you.

I'd say so, what else is in your system? The 7900GTX is to use 80w at full load at max I believe, so if ~400w is sufficient for the rest of your system (Leave the 40w for safety space and for the given or taken errors during calculating total wattage, leaves room for additional upgrade too).

I figured it out with one of those wattage calculators. I got 242 without moniter added in. So I think it will handle it wonderfully.
