The MWE Bronze V2 offers 80 PLUS Bronze certification, guaranteeing an average efficiency of 88% at typical load. The DC-to-DC + LLC circuit design allows the unit to convert power from the single +12V rail reliably, efficiently, and safely for a better overall user experience. The thermally sensitive HDB fan cools based on temperature, adjusting constantly as the systemís needs change. Not only does this waste less power but it also creates a quieter overall user experience by not running the fan at maximum noise level when not needed. For a great mid-tier computing experience, choose the MWE Bronze V2.Cooler Master MWE 550 Bronze V2 ATX 80 Plus 550W Power Supply Unit
