Based on their company name, you wouldn't expect Cooler Master to be a big player in the power supply market. Indeed, Cooler Master's product line has a definite focus on cooling products and accessories. Nevertheless, in its 18 years of business, CM has had a lot of time to expand into auxiliary markets, including power (and, more recently, media devices).

In the past, Cooler Master's power supply offerings have showcased features such as high efficiency and silent performance. With their new GX (Gamer Xtreme) line, they hope to combine these features into one high power, super stable product. Today, we have for review Cooler Master's new GX 750W PSU. Full specs, from the CM website, are:

  • Compliance with the latest Intel standard ATX 12V V 2.31.

  • Single +12V rail for the most demanding SLI configurations.

  • High efficiency design that meets 80 Plus requirements (85% typical).

  • Ultra-silent operation with intelligent 120mm fan speed control.

  • Multiple protection design (OVP/UVP/OPP/OTP/SCP).

  • High reliability (MTBF >1000,000 hours).

  • Double layer EMI Filter restrains noise and injury to end-user.

  • Huge bulk capacitor for hold up time >17ms at full loading.

  • Integrating Active PFC with PWM combo controller not only make PFC higher than 0.99, but also raises efficiency.

  • Efficient transformer for reducing 5Vsb power loss when the system is at turn-off and sleep modes.

  • Five-year warranty.

And power chart:

80 Plus certification and a hefty 60A on the single 12V rail mean this product has all the makings of a solid PSU. Continue on as we put it to the test...
