Need PSU suggestion for Brisbane build

[kitfox]

I'm building a secondary computer for some lan gaming. I'm trying to keep the budget as a low as possible by reusing old parts and buying on sales/rebates. But...I'm having a little trouble deciding on which PSU to get.


The system will consist of:

Athlon X2 4000+ (Brisbane)
570 SLI Motherboard
2GB DDR2 800
Integrated LAN/Sound
7900GS Video Card
Single HD and DVD-ROM



The PSU's I have my eye on are:

Antec Earthwatts 380W
Cooler Master Real Power 450W
Cooler Master eXtreme Power 550W
Cooler Master eXtreme Power 650W


Which of those do you think would be best for my system (or any other psu's that are relatively inexpensive)? Thanks.

If you're on a budget a quality Seasonic built Antec EarthWatts 380 for $30 AR is hard to beat if you don't mind dealing with rebates. It has more than enough power for your rig, runs quiet, has a 3yr. warranty, and it's more efficient (80+) than the other 3 psu's in your list so it will save you money on your electric bill. It's also able to deliver its full power 24/7 rated @ 50C.

I didn't know the Antec was SeaSonic based...nice. Looks like I'll be picking that one up, thanks for the help!

Quick question, would the Earthwatts 380W be able to provide enough power for a x1950Pro in that setup? (I know it draws quite a bit more power then the 7900GS..)
