Designed to appeal to system builders looking for a truly premium power supply, the Signature 650 boasts many cutting-edge features, several of which have never before been offered in a consumer power supply. The Signature 650 features DC to DC voltage regulator modules which ensure greater system stability, and an 80mm Pulse Width Modulation (PWM) fan which can run up to 50% quieter than standard fans. Not only does the Signature 650 deliver the latest in stability, reliability, and quiet cooling, it also passes 80 PLUS Bronze certification, a rare distinction in energy efficiency attained by very few other power supplies.
