Be Quiet System Power 10 850W Power Supply Review

Overview

The Be Quiet System Power 10 850W power supply unit (PSU) is designed to deliver exceptional performance, efficiency, and silent operation. This PSU is certified 80 PLUS Gold, indicating its high efficiency in converting electrical power. It features advanced technologies like LLC and Synchronous Rectifier (SR) for stable operation and tight voltage regulation. The unit includes a temperature-controlled 120mm fan for optimal cooling without excessive noise.

Build Quality and Design

The System Power 10 850W boasts a robust construction with high-quality components. The fully wired design ensures compatibility with a wide range of PC configurations. The inclusion of multiple protection features such as over-voltage protection (OVP) and short-circuit protection (SCP) safeguards the system from potential damage, providing peace of mind to users.

Performance

Efficiency The PSU achieves an impressive efficiency rating of up to 93.4%, which is a truly outstanding level for this class of PSUs. This high efficiency translates to lower power consumption, lower costs, and cooler, quieter operation. The 80 PLUS Gold certification ensures that the PSU meets stringent efficiency standards, making it a reliable choice for both quiet systems and gaming rigs.

Voltage Regulation The System Power 10 850W features two independent 12V rails, which provide stable power delivery to high-performance components like CPUs and GPUs. The DC-to-DC conversion technology ensures tight voltage regulation even under heavy cross-loading conditions, maintaining consistent performance without compromise.

Cooling Performance The silence-optimized 120mm fan is thermally governed to strike the best balance between effective cooling and quietness. The airflow-optimized fan blades reduce turbulence, enabling best-in-class quiet functionality. The fan operates virtually inaudibly, even under full load, making it an ideal choice for users who prioritize silence.
