be quiet! Pure Power 13 M 650W ATX 3.1 Power Supply

The be quiet! Pure Power 13 M 650W is a high-performance ATX 3.1 compliant power supply unit designed for PC builders who demand exceptional quiet operation and reliable power delivery. With its 80 PLUS Gold certification and semi-passive cooling, this PSU delivers outstanding efficiency while maintaining near-silent operation under typical loads.

Exceptional Quiet Operation with Smart Cooling

The Pure Power 13 M features a 120mm rifle bearing fan with semi-passive cooling technology that remains completely silent during light to medium loads. When cooling is needed, the fan operates between 0-1800 RPM, producing just 30.2 dB of noise – quieter than a whisper. This intelligent cooling system ensures your build stays cool without the constant fan noise common in lesser power supplies.

Future-Proof Compatibility with ATX 3.1 and PCIe 5.1

Built to the latest ATX 3.1 specification, this PSU provides stable power delivery for modern components including high-performance graphics cards. The inclusion of both PCIe 5.1 and PCIe 6+2 cables ensures compatibility with current and next-generation GPUs. With 54.1A on the +12V rail and a peak power capacity of 720W, it can handle demanding gaming and content creation workloads with ease.

Fully Modular Design for Clean Builds

The fully modular cabling system allows you to connect only the cables you need, reducing clutter and improving airflow within your case. Included cables feature standard lengths suitable for most builds: 55cm motherboard cable, 65cm CPU power, and various PCIe and SATA options. This modularity not only improves aesthetics but also simplifies installation and maintenance.

Comprehensive Protection and Reliability

Built with reliability in mind, the Pure Power 13 M includes extensive protection features: over current, over power, over voltage, overheating, short circuit, surge & inrush protection, and under voltage safeguards. With a Mean Time Between Failures (MTBF) rating of 100,000 hours and active power factor correction (PFC), this PSU delivers consistent, safe power to your components.
