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 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…"
