We review and test the Enermax Revolution 85+ 1020W PSU. A near perfect power supply, Enermax recently released the Revolution 85+ series, this BEAST as I like to call it has everything I just mentioned. Modular cables, it's silent, sturdy, rugged and at 220 Volts this puppy can achieve a power efficiency of 87 to 91 percent, and that is just very noteworthy.
