Hello,

I'm building a new computer. I have all the parts that I want to use, except for the power supply. I have no idea which one is the best to use.

The spec of the machine is:

CPU: Intel i5 2500k 3.3GHz.
MOBO: Gigabyte Z68AP-D3
RAM: 8GB Kingston HyperX Genesis Grey 1600MHz
GFX: ATI HD6850 1GB
SSD: OCZ Vertex 60GB
HD: 1Tb Samsung SpinPoint 7200rpm

With a few fans and a cooler on there, haven't decided that either, actually.

Any idea? Thinking I need 650w minimum but don't know if I should get higher.

Thanks.

A 650W PSU could probably run a system with three 6850s. This is because 6850s are fairly power efficient. Bottom line is that you don't need to worry about the wattage so much as the quality and the features that you need.
You would have to worry about the wattage if you want to give yourself as many upgrade options as possible.
