Introducing the all NEW Cooler Master GX-Series Power Supplies
Cooler Master offers an extensive range of power supplies that allows for a perfect fit for any system. The latest addition from Cooler Master is a range of 550W, 650W and 750W power supplies that specifically targets upper mid-range to high-end gaming systems, the Cooler Master GX-Series.†
The Cooler Master GX range of power supplies feature a single powerful +12V rail that has been designed to deliver more than ample power to dual graphics card systems, no matter if you use SLI or CrossFireX. On top of this you also get a wide range of other high-quality Cooler Master features which makes the Cooler Master GX range the ideal solution for your system.
Designed for dual GPU systems
All of the power supplies in the Cooler Master GX range have been specifically designed for dual GPU systems and the 750W model also carries SLI certification for high-end Nvidia GTX graphics cards, as it offers four PCI Express power connectors.
Up to 85% efficiency
All of the power supplies in the Cooler Master GX range features up to 85% power efficiency and are 80 plus rated. This means more power goes where itís needed and less power is wasted in heat.
The Cooler Master GX series comes with a range of advanced features such as a powerful single +12V rail, huge bulk capacitors with a >17ms hold up time which means that the power supply will be able to handle peak loads better, low noise dual layer EMI filters that reduces noise in the power lines, an energy efficient dual mode Active PFC/PWM controller, an efficient transformer that reduces the 5Vsb power loss when the system is in standby mode and a wide range of protection designs that will prevent damage to the system in case of a malfunction.

I'm pleased to see the CoolerMaster GX series carries the 80 Plus certification - and, this particular model is also officially certified for SLI. Lifetime is brilliant at over 100000 hours. The selection of connectors is also vast, which can only be a good thing (but sometimes a pain to hide in a small case!). Also worth noting - the connector section is wrong for the 750w unit - this particular unit has 4, yes four 6+2pin PCI-e connectors - ace for SLi systems. Onto the PSU itself.
