Cooler Master iGreen 600W Power Supply
 

Cooler Master's iGreen series of power supplies are targeted as being high efficiency, super silent, and SLI & Crossfire ready. The increased power consumption of high-end PCs with multiple CPUs and GPUs puts a higher demand on the power supply, and the iGreen series is designed to meet these needs. Currently the iGreen series is available in 500W and 600W models. Both models feature a "Double Forward Switching Circuit" technology for 85% efficiency!
