When you hear the name Cooler Master, most likely you immediately think of a company that specializes in cooling products. While that is not inaccurate, they also make other computer equipment, such as cases and power supplies. Cooler Master has sent over a new product from their iGreen series of power supplies that includes models rated at 430W, 500W, and 600W. Other than the power output, these units boast high efficiencies, silent operation, and powerful 12V rails. I will be looking at the iGreen 500W to see how well it performs compared to other SLI ready power supplies.
Features and Specifications (taken from the Cooler Master website):
Cooler Master's power supply has been praised highly of its high efficiency and stability. In the year of 2006, Cooler Master will launch a new series of power supply iGreen Power 430W/500W/600W. iGreen Power is the world first power supply which achieves 85% efficiency through Double Forward Switching Circuit Technology. This intelligent circuit configuration stabilizes your running system without costing you a fortune. While staying true to our original mission to provide the best products, Cooler Master is responding to the environmental concern around our globe. We make this iGreen environmental friendly - it has met the Energy Star and Blue Angel requirements.
