System Power 10 850W has been built with price-conscious users in mind that do not want to dispense on reliability and quietness. Features such as LLC + SR + DC-to-DC topology and Dual-Rail operation underline the value System Power 10 850W offers even at entry-level.
System Power 10 850W is certified 80 PLUS Gold with an efficiency rating of up to 93.4% – 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 850W is the price-conscious choice!
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.
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.
System Power 10 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.
“System Power is the entry to silent PC building, which still offers up to 80PLUS® Gold efficiency. With System Power we offer you everything you need for a reliable and cost-efficient operation.”
Christian Berndt, Product Compliance Manager
