Highlights

Exceptionally Quiet, Superior Reliability, Great Value Pure Power 11 500W CM offers peerless dependability and best-in-class features. Whether you’re assembling a very quiet system, upgrading an existing PC, or building a multi-GPU gaming system, your build will benefit from this PSU that simply has the best combination of features at a very popular price. 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.
