80 PLUS® GOLD CERTIFICATION

Very high operating efficiency

Pure Power 11 CM 500W is certified 80 PLUS Gold with an efficiency rating of up to 92% – a truly outstanding level for this class of PSU. The most compelling benefit: lower power consumption and consequently lower costs, and cooler, quieter operation.

POWER AND COMPATIBILITY FOR YOUR SYSTEM

The best combination of features and performance at a very popular price

Pure Power 11 CM offers 500W of continuous power with 2 independent 12 V rails for signal stability and 2 PCI express connectors for powerful GPU systems. It is suited to very quiet systems, for upgrading or building multimedia or powerful GPU systems.

INNOVATIVE TECHNOLOGIES

DC-to-DC, Active Clamp and Synchronous Rectifier

The use of Active Clamp and Synchronous Rectifier technologies provides very stable operation. The PSU is equipped with DC-to-DC conversion for even tighter voltage regulation under heavy cross-loading conditions. This ensures secure operation for next generation processors and graphics cards.

EXCEPTIONALLY SILENT OPERATION

Achieved by a silence-optimized 120mm be quiet! fan

The silence-optimized 120mm be quiet! fan is thermally governed to strike the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, enabling best-in-class quiet functionality and the almost inaudible operation that be quiet! is famous for. 

SEMI-MODULAR AND FLAT CABLES

Total convenience and design for your system

Pure Power 11 CM 500W is certainly eye-catching. The semi-modular cables are enhanced with premium black sleeves. The flat cables used for the PCI-express connection and drives simplify installation as well as keeping the system tidy.
