Be Quiet! System Power 10 550W Power Supply Unit

The Be Quiet! System Power 10 550W delivers reliable, quiet power for budget-conscious PC builders who refuse to compromise on performance. This ATX power supply combines 80+ Bronze efficiency with temperature-controlled operation, making it an ideal choice for mid-range gaming and productivity systems.

Quiet Operation with Temperature-Controlled Fan

Equipped with a 120mm ball bearing fan, this PSU maintains whisper-quiet operation across varying loads. At 20% load, noise levels measure just 8.6 dB(A), rising to only 9.4 dB(A) at 50% load. The temperature-controlled fan adjusts speed based on thermal requirements, ensuring your system stays cool without unnecessary noise.

Strong 12V Rail for GPU Support

The single strong 12V rail design provides stable power delivery for demanding graphics cards. With 2 x PCI-e 6+2-pin connectors, this 550W PSU supports modern GPUs while maintaining rock-solid voltage stability through DC-to-DC technology. Tight voltage regulation ensures consistent performance even under heavy loads.

80+ Bronze Certified Efficiency

Achieving up to 89.1% efficiency at 50% load, this power supply meets 80 PLUS Bronze certification standards. The active PFC design reduces energy waste, with efficiency ratings of 87.4% at 20% load and 85.7% at 100% load when operating at 230V. Stand-by power drain remains below 0.15 watts, minimizing energy consumption when your system is idle.

Comprehensive Cable Configuration

This fully wired PSU includes all necessary connectors: 1 x ATX motherboard (20+4-pin), 1 x P4+4 CPU connector, 1 x P4 CPU connector, 2 x PCI-e 6+2-pin for graphics cards, 1 x PATA, and 6 x SATA connectors. The attractive black flat cables improve airflow and cable management within your case.

Complete Protection Suite

Your components stay protected with multiple safety features including OCP (over current protection), OVP (over voltage protection), UVP (under voltage protection), SCP (short circuit protection), OTP (over temperature protection), OPP (over power protection), and SIP (surge & inrush protection). These safeguards defend against electrical issues that could damage your valuable hardware.
