Proven Reliability and Quiet Operation
Be Quiet! System Power 11 550W (BP010EU) delivers reliable power for entry-level systems with ATX 3.1 compliance and 80 PLUS Bronze efficiency up to 89.7%. The non-modular design with black flat cables ensures straightforward installation while optimizing airflow. A single +12V rail (45.83A, 550W) supports modern GPUs and CPUs effectively.
The 120mm rifle bearing fan provides temperature-controlled cooling (0-1800 RPM) for whisper-quiet operation at just 24.2 dB max noise. Comprehensive protections guard against over-current, over-power, over-voltage, overheating, short-circuit, surge, inrush, and under-voltage. With 100,000 hours MTBF and 5-year warranty (inferred standard), it’s ideal for budget gaming or office PCs.
