Cheapest PSU for this setup?

[Noya]

Opteron 165 overclocked
4 x DDR Dimms
3 x 7200rpm HDDs
2 x DVD drives
7600gt (probably replace with x1950xt or 8800gts 320 soon).

I see buy.com has the Corsair 520watt for $90 after a $10 rebate.

Or would something like this fit the bill:

A quality 380W psu would power your rig. However if you can afford the Corsair HX520 then by all means get it. Not only will it give you plenty of headroom for a 2900XT or 8800GTX, you'll also have a 5 yr. warranty for a piece of mind. The Corsair VX450 is also a solid choice that is only $70 AR
