80 PLUS® GOLD CERTIFICATION

Very high operating efficiency

Pure Power 11 FM 850W is certified 80 PLUS Gold with an efficiency rating of up to 93.3%  – a truly outstanding level for this class of PSU. The most compelling benefit is lower power consumption, lower costs, and cooler, quieter operation. Whether you are building a very quiet system or gaming system: Pure Power 11 FM 850W is always the correct choice!

MODULAR CABLES

Utmost convenience and compatibility

Thanks to the modular cables, all cables that serve no purpose are left out. For this reason, systems always appear very tidy. At the same time installation is performed much more conveniently. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures prevail inside the case.

POWER AND COMPATIBILITY

For your system

Pure Power 11 FM offers 850W of continuous power with 2 independent 12V rails for signal stability and 4 PCI express connectors. It is suited to very quiet systems, upgrading or building multimedia, gaming or systems with an overclocked high-end GPU.

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-CLASS TECHNOLOGIES

Compatibility for the systems of tomorrow

LLC and Synchronous Rectifier (SR) provide very stable operation and enhanced voltage regulation. The PSU is equipped with DC-to-DC conversion for tight voltage regulation even under heavy cross-loading conditions. This ensures reliable operation with the current generation of processors and graphics cards.
