Is my power supply the problem?

Lately, I've been getting power failures on my computer, where it just loses power instantly and restarts. About half the time, its just a clean power loss, but every other time my screen will freeze and i'll hear a loud buzz for a second or two before it loses power. Now, the buzz might be comming from my case, but its possible that it might just be sending a messed up audio signal to my speakers when it happens. It only happens after about an hour gamming, I don't think its my cpu because the temp is always below 50 C, and i doubt its my hard drive because i haven't suffered data loss. I don't think its my video card because it doesn't always happen at graphics intensive parts of the game. The only thing left that seems like it would cause power loss is my power supply, but I don't have another one to test with. Here are my specs:

e6700 @ stock speed
Powercolor x1950xtx
Asus P5W DH Deluxe
2GB Corsair PC6400
WD Caviar 320GB
Thermaltake Toughpower 600W

My power supply is the only thing I have that I've heard mixed reviews about. Does this seem like a problem that my power supply would cause?
