-------------------
My computer runs fine under load, even after i pushed it listening to iTunes while running counter-strike source and World of warcraft all at the same time (just tabbing between progs after i die). but when i let it idle overnight, i usually wake up and find that it restarted while i was asleep...and i know nothing is running. Only thing i can think of is that im getting power sags, but this psu should run this setup fine i would think. my temps are beautiful. ideas? or is 620w not enough? what would be a good utility to run to check this out?

Re: 620watt PSU enough?

Last I remember hearing, 8800GTX video cards were recommending a 750-watt PSU due to the high demand for power.

Typically, instability at load is where PSU insufficiencies would show. "Asus Probe", which came with your MB, can monitor and keep record of voltages/temps and fan speeds. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

Overclocking (like your GPU) requires ample PSU headroom.

Cheap 620W, no, not good enough. A good name brand (Silverstone, OCZ, Corsair, Zippy, Tagan, etc..) high quality 500W PSU is fine for a single GTX.

I havent woke up to a reboot since i posted this. I have NO idea whats going on. Tested to aerocool with the xoxide psu tester and everything was running perfect...wtf! i overclocked the cpu and ram...sitting at 3.2 ghtz right now, stress test, no errors, no reboot. I think ive got a magical psu. just needed a little break in maybe? who knows.
