Exceptionally Quiet, Superior Reliability, Great Value
Pure Power 11 400W offers peerless dependability and best-in-class features. Whether you’re assembling a very quiet system, building a multi-GPU gaming system, or upgrading an existing PC, 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 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
The best combination of features and performance at a very popular price
Pure Power 11 offers 400W of continuous power with 2 independent 12V rails for signal stability and 2 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
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.
HIGH-QUALITY SLEEVED CABLES
Keeping your system tidy and good-looking
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.
