Be Quiet! Pure Power 12 M 550W - ATX 3.0 Modular Power Supply

The Be Quiet! Pure Power 12 M 550W delivers reliable power with modern connectivity for gaming and high-performance systems. This fully modular ATX 3.0 power supply features 80 PLUS Gold certification with up to 92.8% efficiency, ensuring lower power consumption and quieter operation.

ATX 3.0 and PCIe 5.0 Ready

Built for next-generation graphics cards, the Pure Power 12 M includes a native 12VHPWR connector supporting PCIe 5.0 GPUs with 300W power delivery. Two additional PCIe 6+2-pin connectors provide compatibility with current-generation graphics cards, making this PSU versatile for both present and future builds.

Exceptional Efficiency and Stability

The 80 PLUS Gold certification ensures efficient power delivery across all load levels. Advanced LLC topology provides rock-solid voltage regulation, while dual independent 12V rails deliver 550W of continuous power. The PSU handles power excursions up to double its rated capacity, ensuring stable operation even during demanding transient loads from high-end processors and graphics cards.

Silent Operation

The 120mm rifle bearing fan operates at whisper-quiet levels, measuring just 8 dB(A) at low loads and 17.1 dB(A) at full capacity. Temperature-controlled operation balances effective cooling with minimal noise, while airflow-optimized fan blades reduce turbulence for best-in-class quiet performance.

Fully Modular Design

Connect only the cables you need with the fully modular cable system. This simplifies cable management, creates a cleaner build appearance, and improves airflow inside your case for better cooling and reduced noise levels.

Comprehensive Protection

Multiple protection circuits safeguard your components: over temperature, over current, over power, short circuit, over voltage, under voltage, and surge protection. With an MTBF rating of 100,000 hours and a 10-year manufacturer's warranty, the Pure Power 12 M is built for long-term reliability.

Complete Connectivity

Includes 1x ATX 20+4-pin motherboard connector, 1x P4+4 CPU connector, 1x P8 CPU connector, 1x 12VHPWR cable (300W), 2x PCIe 6+2-pin connectors, 5x SATA, and 2x PATA connectors. The 160 x 150 x 86mm form factor fits standard ATX cases.
