If you are a PC enthusiast, the name Cooler Master is as much of a household name as Kenmore or General Electric. If you are not a PC enthusiast, let me give you a brief rundown on what Cooler Master does. Cooler Master's roots have been in the PC cooling market for many years. They have branched out and are now bringing to the consumer a full line of computer cases, fans, heat sinks, accessories and power supply units (PSU). While branching out though, one thing has remained the same, their commitment to quality and their drive to produce the industries best cooling solutions.

Today I have the pleasure of reviewing the Cooler Master Real Power 530W SLI (RS-530-ACLY.) And, as you will see, there are only a few slight changes they have made to it from the non SLI versions.
