Product on Review: Cooler Master GX 550W
Manufacturer: Cooler Master
Street Price: Approx 60



Cooler Master announced the GX series at the end of January and was showcasing these products to the world at CeBIT just last week. The GX series stand for Gamer Xtreme and comes in three power ratings - 550W, 650W and 750W hoping to target mid-range to high-end gaming systems by offering a single +12V rail designed to provide sufficient power to dual graphics card systems such as CrossFireX and SLi. The 750W version even comes with four PCIe connectors.

Up to 85% efficiency is available with all of the GX units being certified with 80 plus rating - good news if you are looking for a power supply unit capable of handling multiple graphics cards.

Cooler Master have the following to say about the GX series.

The Cooler Master GX series power supplies stand for Gamer Xtreme, the evolved version of extreme power plus. With up to 60 amps on a single rail, there is enough power to start up a car. Imagine what it can do for your system. With so much power at your disposal, Cooler Master ensures the most stringent safety standards are met. The extended 5-year warranty is included to give you further piece of mind.
