How much power do I need?

[Nugzy]

Right now I have a 500w power supply, but Im thinking Im gonna need something bigger. Here are my system specs:


Asus P5B-E
e6600 (overclocked to 3.2, soon to be 3.6)
2GB g.skill DDR-800 RAM (will be overclocked)
8800gts 320MB (overclocked to 600/2000)
500GB Sata HDD
2nd 500GB Sata HDD
DVD+RW DL IDE Burner
Sondigo Sound Card
3-4 case fans, and 1-2 heatsink fans

How much power should I get to support all this?

Thanks in advance for any help!

So it doesnt matter if its 500w or 1000w, as long as it offers that?
