-Intel-E series mobo DZ68BC
-Seagate Barracuda 1TB 7200RPM SATA 6.0gb

Nvidia recommends 550-watt power supply with a minimum of 38 amps on the +12 volt rails. Unless you plan on SLI in the future, you don't need more than a good 500-550W PSU. The Seasonic S12II-520 has 40A on the 12V rail...great PSu and 5 yr warranty: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Rosewill Capstone 550W is another great PSU; 45A on the 12V rail and 80+ Gold certified: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

A great article on power consumption in modern PCs: http://www.silentpcreview.com/article1245-page1.html

Modern PCs require a lot less power than most people think. Their testing showed an i5 2500K and an HD6870 at stock speeds only drawing 271W while running Prime95/Furmark simultaneously.

I personally say that if you have money, go for the corsair ax750 or seasonic x-series 750 watt. The latter tends to go on sale often (I got one for 120$), and it is regarded as one of the best PSU's you can buy. Plus it is modular.

You never know what he may do. It is better to get a higher wattage supply, so that you can upgrade to a sli or such. Good power supplys have a long lifespan, so you may end up using this on a more power hungry rig in 6-7 years too.

Rugger and e56imfg are correct in their recommendations. As long as you only plan on running a single GTX 570 then 550 watts is fine. Amps are what you should be looking at anyway. If you plan on running 2 x GTX 570s in Sli then I would recommend 800-850 watts if you plan on overclocking.

The Nvidia recommendations are based on a generic power supply not a quality model.

Corsair, Seasonic, PC Power and Cooling, XFX, Enermax, Silverstone, OCZ and Antec are quality brands.
