My power supply is 330W, at least that's what I think it says.. I'll quote.. "+5V & +3.3V Combined load 215W." "+5V & +3.3V & 12V Combined load 330W." And no, how do I set it to AGP X4, or turn off Fastwrites? ANd what is it? And yes, I've the latest drivers for my video card. And for my motherboard, I just installed what was on the CD that came with it. On the official ASUS website I could only find BIOS updates, which I have already gotten.
