80 PLUS® GOLD CERTIFICATION

Very high operating efficiency

System Power 10 U 850W is certified 80 PLUS Gold with an efficiency rating of up to 93.3% – a truly outstanding level for this class of PSUs. 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: System Power 10 U 850W is the price-conscious choice!

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 all systems

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. 

HIGH PERFORMANCE FOR YOUR SYSTEM

Proven reliability for CPU and GPU

System Power 10 U 850W provides stable and dependable power for CPU and GPU. It is equipped with 2 independent 12V-rails and supports several graphics cards with 4 PCI express connectors for GPU support.
