Antec Signature 850

Designed to appeal to system builders looking for a truly premium power supply, the Signature 850 boasts many cutting-edge features, several of which have never before been offered in a consumer power supply. The Signature 850 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 850 deliver the latest in stability, reliability, and quiet cooling, it also passes 80 PLUSÂ Bronze certification, a rare distinction in energy efficiency attained by very few other power supplies.
