Corsair Gaming Series GS800 Power Supply Review
 

Corsair's new Gaming Series power supply is a solid contender.
For the price, you get a whole lot of power supply. While efficiency
isn't up there with some more expensive units, the GS800W only claimed
to be 80Plus. Still, the efficiency numbers are good even under heavy
stress.
