      "The Cooler Master GX 750W looks like a good option for users looking for a mainstream 750 W power supply; however the power supply only has four Molex connectors. This PSU ran solid through everything I threw at it."

      "The Cooler Master GX 750 has a few things going for it right off the bat. The aesthetics aren't terribly unique but the matte black finish should fit handsomely into any case. There is also ample power across the rails, all which fell into acceptable power fluctuations.  60A available on the single +12V rail is plenty for a unit of this power range, and the GX 750W runs pretty cool and quiet."

      "This PSU ran rock solid through everything I threw at it. I overclocked the i5-661 to 4.4 Ghz with no power fluctuations or any hardware failures. This power supply offers optimal power for any overclocker while still keeping the noise to a minimum.  Would I recommend the GX Series? Absolutely! If you are in the market for a great PSU with rock solid voltages the GX series is for you."
