Characteristics
POWER AND COMPATIBILITY FOR YOUR SYSTEM
The best combination of features and performance at a very popular pricePure Power 10 CM offers 400W of continuous power with two independent 12Vrails for signal stability and two PCI express connectors for multi-GPU systems. It is suited to very quiet systems, for upgrading or building multimedia or multi-GPU gaming systems.
80PLUS® SILVER CERTIFICATION
Very high operating efficiencyPure Power 10 400W is certified 80PLUS® Silver with an efficiency rating of up to 91% – a truly outstanding level for this class of PSU. The most compelling benefit: lower power consumption and consequently lower costs, and cooler, quieter operation.
INNOVATIVE TECHNOLOGIES
DC-to-DC, Active Clamp and Synchronous RectifierThe 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! fanThe 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.
MODULAR CABLE MANAGEMENT WITH FLAT CABLES
Total convenience and design for your systemPure Power 10 400W CM is certainly eye-catching. The modular cable management is enhanced with premium black, sleeved cables. The flat cables used for the PCI-express connection and drives simplify installation as well as keeping the system tidy.
