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.
