It may only be flexing 600 Watts. And, it may not look like it has anything special underneath that clean, sexy, black exterior. But, the CoolerMaster Silent Pro M 600W Power Supply does have some extra horse power hiding underneath the hood. This is why I suggested having a look at the test results before running off to buy a 700 Watt PSU. The Silent Pro M 600W is like a "sleeper" hot rod PSU hiding underneath that cool, black
exterior.
