Power supply help? Pretty please?

OK, I've tried everything, and I've about given up. The only thing I can think of that could be causing my computer woes is the PS.

And it makes sense-- I'm running a helluva lotta stuff off an old Enermax 350W power supply. And monitoring my power shows that my +12 does dip to 10 much more often than I'd like.

So it's time to replace the power supply. Past time, maybe.

I'm thinking about getting this Thermaltake TR2 500W. $60 ($80, with a $20 rebate) sounds like a great deal.

What do you think? This is (more or less) my current system.

I appreciate your help, as always :)

PS, I love you

Hm. Now I can't decide between 500W and 600W. I've added a few things to that old system, including a massive hard drive, dvd rw w/ lightscribe and a USB 2.0 controller.

In any case, I want Active PFC, right? I have an Athlon XP cpu-- do I need two fans? If one's OK, these two look like nice choices at excellent prices:

COOLMAX CP-500T EPS12V 500W Power Supply - Retail
HIPRO TOP-600P5 ATX V2.01 600W Power Supply - OEM

Any thoughts? If I do need two fans, then that changes everything.

I think the Cooler Master continuous sounds like the better choice, but my knowledge of Power Supplies is rather limited. It's more than I wanted to spend, but seems tres secksay.

What do you think? Maybe you have a better idea?

Last post on this subject, promise :)

Heh. I discovered this gaming site that had tiered ratings for power supplies, and ended up going with a 500W Enermax Liberty.

A bit more than I'd wanted to spend, but it's rock solid, and should serve me well for a very long time.

Overall, I've been tremendously pleased with my current Enermax-- the fact that I'm only getting rid of it after four and a half years because my computer's outgrown it should stand as a testament to its quality

Thanks for your help, folks :)
