CoolerMaster Real Power Pro 750 watt Power SupplyMakaveli -
In order to test this power supply, I pulled out my RadioShack 29-Range Digital Multimeter so that I could check the voltages of the rails at idle and under load. To load up the system, I'm running OCCT for the CPU (to make sure both cores are fully loaded), 3DMark06 for loading the video card and HDTach to load the hard drives. I’m comparing the Cooler Master Real Power Pro 750watt power supply against my XG 600watt power supply to see how the 12 volt, 5.0 volt and 3.3 volt lines measure up to one another. In any test, you don’t want to see a drop in voltages. Instead, you want to see the voltages stay as close as possible to the stated values of 12.0v, 5.0v, and 3.3v.

After I tested both units, I couldn’t believe just how much my old XG 600watt power supply fluctuated. The CoolerMaster stayed right on track and didn’t differ from what it said the voltages should be. Clearly, the CoolerMaster Real Power Pro 750watt power supply was the winner in this battle.
