PRODUCT SPECIFICATIONS AND FEATURES




As you can see, the GX 750W has great specs and is feature rich. About the only thing missing is modularity, but this PSU makes up for this in size. Or rather lack of it. The GX 750W is really compact for a PSU with this kind of capacity.



The Cooler Master GX series is clearly aimed at the high-end PC enthusiast and marketed as a premium product. As such, the GX 750W should, and does, have some premium features and specs. As you can see, Cooler Master doesn't disappoint. Let's take a moment to go over one of the high points that make this a premium PSU.


First of all, let's discuss the 80 PLUS certification. To quote from the website (see it HERE ,) “80 Plus is an innovative, electric utility-funded incentive program to integrate more energy-efficient power supplies into desktop computers and servers. Participating utilities and energy efficiency organizations across North America have contributed over $5 million of incentives to help the computer industry transition to 80 PLUS certified power supplies.”

As you can see from the above table, to achieve the 80Plus certification, the PSU must demonstrate 80% or better efficiency at 20%, 50% and 80% of the rated capacity. In 2008 Bronze, Silver and Gold categories were added and the corresponding efficiency benchmarks are listed above. 80Plus certified power supplies, when compared to less efficient PSUs, will generally be quieter while producing less heat, have higher quality components and save you a little money on your electric bill. However, the money saved is unlikely to offset the higher cost of an 80Plus unit, as the savings calculator on the 80Plus website shows. Nevertheless, for me, the lower temps, quieter operation and quality components found in 80Plus power supplies make up for the extra cost, in most cases. This Cooler Master offering carries an 80Plus rating, although the specifications would seem to indicate that the unit qualifies for a Bronze rating.

 

PRODUCT COMPOSITION




The GX 750W comes in a nicely appointed, informative retail carton. Inside the PSU is cradled in foam and comes with the customary manual, power cord and mounting screws.
