Pure Power 11 series offer 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 one of these PSUs that simply have the best combination of features at a very competitive price.


Pure Power 11 series are certified up to 80 PLUS Gold which has an efficiency rating of up to 92% – a truly outstanding level for this class of PSU. The most compelling benefits being lower power consumption, lower running costs while being cooler and quieter.


Pure Power 11 offers continuous power with two independent 12V rails for signal stability and PCI express connectors for multi-GPU systems. It is suited to very quiet systems for upgrading or building multimedia or multi-GPU gaming systems.


The use of Active Clamp and Synchronous Rectifier technologies provides a 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.


The quiet-optimised 120mm be quiet fan is thermally governed to strike the best balance between effective cooling and quietness. Airflow-optimised fan blades reduce turbulence, enabling best-in-class quiet functionality and the almost inaudible operation that be quiet is famous for.


The Pure Power 11 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.
