Pro-Clockers posted a review on the Enermax Noisetaker 701AX 600 Watt Power Supply
With the growing popularity of hardcore systems running Crossfire and SLI setups, comes the problems of providing enough power to the system. With a lot of companies producing high wattage power supplies, some still lack the necessary ampere of the 12 volt rails. I have many power supplies in my work space that provide a max of about 16 to 18 volts. Our newest test subject provides 22A to each of dual 12 volt rails. The Enermax 701AX packs a lot of power in a small metal box.Enermax Noisetaker 701AX 600 Watt Power Supply Review
