Can a poor PSU cause performance issue?
I have a generic 450W PSU running a Phenom II x2 (unlocked to x4), 4GB RAM, ATI HD5770, 2xOptical drives, 6 case fans, Creative Sound Blaster, etc.
Whenever I run a "heavy" program/utility I can feel the change in sound from my PC. Sometimes, the PC will not boot after I run those "heavy" programs. I then have to unplug it and plug it back in to "reset" the PSU.
Would using a 450W PSU from a known band = better performance and everything?
