I'm looking to upgrade my PSU and would like to hear some advice before I do. Currently I'm running 1 CDRW, 1 DVDRW, 1 floppy, 2 hard drives, 4 80MM fans(case can take one more, I want 5 altogether)and a geforce FX ultra. What would be my best bet for performance/value and total watts? Are name brand PSU's that much better than generic ones? How good of a company is POWMAX(I was looking at a 500w Raidmax psu)?
