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?"

At $120 on NewEgg, the Antec Earthwatts Platinum is not a bad choice for those looking for power and efficiency.  Although it is SLI rated, with only two 6+2 PCIe power connectors you will need to rely on molex adapters to run two cards and at 650W they will not be current flagship models.  Legit Reviews saw some questionable results while testing but for a PSU of this price, especially such a quiet and efficient one, it comes with a recommendation to stop worrying and pick it up.

"When it comes to performance, besides its high electrical efficiency which is expect from an 80Plus Platinum unit. The Earthwatts Platinum 650W PSU also excels in acoustics, with the unit running entirely silent across the entire nominal load range. The high efficiency also allows it to operate at fairly low temperatures as little energy is wasted as heat. Even though most hardcore enthusiasts would find this unit's electrical performance mediocre, we believe that the ripple suppression and voltage regulation of the Earthwatts Platinum 650W unit is more than acceptable for a sub-$100 product..."
