It sounds like the psu needs a little upgrade there. Especially if you have a P4 since i know they can take alot of power there. And the psu shouldn't blow anything because its not forcing more power to everything, just giving the cables/psu more leg room for more stuff. And remember, for power supplies, its quality over quantity (quantity meaning wattage). From what I've heard, I think thermaltake, forton, and another one are the better ones to get. But if you can't find them, get a decent priced 400-420w psu and you'll be fine.

I'm still using my stock 350w that came with my case, and I have so much crap hooked up to it I still don't understand how it runs fine with no random reboots.
