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 400W CM 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.
