If the 1000W Rosewill PSU that Lee just reviewed is more power than your system needs, [H]ard|OCP has a slightly less powerful 660W 80Plus Platinum PSU you could consider that Lee has also looked at.  At $150 it is fairly expensive for a 660W PSU, but a 7 year warranty and a Platinum efficiency rating do not come cheap.  With four 6+2 PCIe connectors and up to 55A on the 12V rail and an unparalleled peak change of 0.01v this will solidly power several GPUs.  [H] was so impressed that they couldn't think of a PSU to contrast against, this unit is miles ahead of the competition when it comes to the purity of the voltages provided.

"Seasonic's new SS-660XP comes to us boasting high end PSU features in what we can consider a smaller wattage package than what we are used to seeing. This PSU has a fully modular design, great efficiency, optional Hybrid fan control allowing fanless, silent, and normal cooling modes. Does Seasonic have another winner?"
