alrighty, it has been a couple days now and it's still running fine on PS#3. :dunno: I've left all non-essentials (diskdrives, usb ports, extra HDs, etc) unplugged. I'm thinking If it lasts another week, I might fork over a few bucks on a 500w PS and then start installing the rest of my stuff. this assumes I was overloading the first 2 PSs. the first PS was 350w, the second was 300, the third is completely unknown (no coverplate on it).
