For the parts you listed I would say you need something that is at least 400w of solid power. Most Cooler Master PSUs are over-rated by 100w, I think it's because they rate it at peak envelope power rather than continuous. The Corsair will probably be your best bet.

Also note, that Antec you listed is a little dated. Most people won't buy a PSU with a 80mm fan... that is like a throwback to the Pentium 4 days. Corsair and Seasonic will be the most solid, but if you like Antec, try a little better one like this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The Corsair VX550 out of those followed by the Antec EA500D which has two +12volt rails of max 22amps each but 444watts = 37amps total.

I'd go with the Corsair 550W for the price, Ratings, and all the power youll need.

+1 for the Corsair 550vx being the best option.

And as been stated two post ago DDRIII will not be supported by your board only a few Intel 775 boards can.

For $69, this is about the best choice you can make. Cheaper and, with its 9.5 performance rating, a substantial upgrade over the Coprsair, Antec and CM models listed.

That's a great deal, but those mail in rebates take almost 3 months to receive most of the time sometimes longer. I myself love rebates like that, its found money when they come in. OP if you can afford to spend a little more now that XFX unit is a great unit.

I put Thermaltake PSU's in the same hit and miss group as Cooler Master, they are good companies to buy Cases and Coolers from. I stick with my recommendations above.
