Reasons To Buy
80 PLUS GOLD CERTIFICATION
Pure Power 11 400W 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
Pure Power 11 offers 400W of continuous power with two independent 12V rails 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.
INNOVATIVE TECHNOLOGIES
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
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.
HIGH-QUALITY SLEEVED CABLES
Pure Power 400W is equipped with high-quality sleeved cables that simplify component installation, increase airflow and improve cooling. The All-in-one cable has a convenient easy-plug HDD connector.
