Windows 7: power supply?

I have to agree with Kodi. The PSU you selected may not be the best option. I used an Antec PSU for my HP Pavilion and it fit perfectly. The one I used is currently not available but it was similar to this one: - Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power Supply
For a few bucks more you can also get a 550 Watt box.

No good. Efficiency is only 65% - but it should be at least 80%. Why do you insist on those rinky dink units where there are a lot of excellent units on the market. The PSU can give you a lot of trouble if you settle for a cheap deal.

Believe it or, a Corsair 450W is a better power supply than the 600W one linked.

There have been some other good Power Supplys suggested, but I would highly recommend Corsairs PSUS. Either the 450W or a 550W would be more than enough.

The 400W (32A) Corsair would likely be enough for your system & that card as well.

I have 1 PC here that runs a E8400, 4GB RAM & a 512MB HD 3870 GPu on the 400W Corsair without issues.
Not all 400W PSUs can do that however. And thats the point everyone is making here.

Wattage in itself doesnt mean that much. Its all about the 12V rail amperage, and effeciency.

Whichever recommendation you decide to choose, bottom line, get a quality PSU.

Good link Kodi!

So long as its a quality PSU, you really do not need 700+ watts.

In most cases 550-650 of a quality supply will power mid-higher end setups.

Mind you, highend multiple GPUs may need more juice, but for a single card this is really all you need.
