Good power supply for decent gaming PC?

[cabernet]

I just built a PC and it has some high end parts like EVGA Geforce Nvidia 8600GTS graphics card, EVGA 650i motherboard, and E6600 Intel processor and I'm using a 600w power supply, its actually a 585w power supply for some reason but is this enough for this rig? http://www.newegg.com/Product/Product.aspx?Item=N82E16817182062

You already have the PSU? Yes, it's more than sufficient for your system.

if you have a quality PSU. a 400 - 500 is already more than enough if you don't do some extreme OCing. and your graphic card isn't that great
