This article covers Be Quiet!ピュアパワー 13 M ATX 3.1.
Overview
The be quiet! Pure Power 13 M 750W is an ATX 3.1 compliant power supply with 80 PLUS Gold certification, achieving up to 94.3% efficiency. It features a 12V-2x6 connector for the latest PCIe 5.1 graphics cards and can handle peak loads up to twice its rated wattage, making it a reliable choice for modern and future builds. Designed with silence in mind, this PSU uses a large fan with a semi-passive mode that stops the fan entirely under low load. The LLC topology ensures stable voltage regulation, while the semi-modular cable design keeps your build tidy and improves airflow. Positioned in the mid-range segment, the Pure Power 13 M 750W offers a great balance of efficiency, quiet operation, and future-proof connectivity. It's ideal for mid-to-high-end gaming PCs and quiet workstation builds.
Compatibility Guide
Standard ATX form factor fits most mid-tower and full-tower cases. One 12V-2x6 connector directly supports PCIe 5.1 GPUs (e.g., RTX 40 series and beyond). Four PCIe 6+2 pin connectors provide backward compatibility with older GPUs or multi-GPU setups. 750W capacity is suitable for systems with a CPU up to ~150W TDP and GPU up to ~250W TDP (e.g., RTX 4070, RX 7800 XT). * Cable lengths are generous enough for large cases; the 24-pin and CPU 8-pin cables are fixed (semi-modular).
Product Info
Released in late 2025, the Pure Power 13 M 750W retails for around ¥30,000–¥31,000 in Japan. Warranty is typically 3 years (check manufacturer for details). It's available through Japan and major electronics retailers. Market positioning: mid-range. It competes with the Corsair RM750e and Seasonic Focus GX-750, but stands out with its ATX 3.1 compliance and superior noise control.
Best Use Cases
Silent PC builds: The semi-passive fan mode and large fan keep noise to a minimum. Perfect for HTPCs, office PCs, or any environment where silence is key. Mid-range gaming rigs: Pair with an RTX 4070 or RX 7800 XT for a well-balanced system with headroom for overclocking. * Energy-conscious users: 80 PLUS Gold efficiency reduces electricity bills, especially under sustained loads like rendering or mining.
Things to Consider
750W may not be enough for flagship GPUs like the RTX 4090 or RX 7900 XTX. Consider an 850W+ unit for such builds. Semi-modular design means the 24-pin and CPU 8-pin cables are permanently attached. If you prefer full modularity, look at the Corsair RM750e or Seasonic Focus GX-750. The cables are reported to be somewhat stiff, so careful routing is advised. Competitors offer longer warranties (Seasonic 10 years) or full modularity at similar prices. Choose based on your priorities: silence (be quiet!), warranty (Seasonic), or modularity (Corsair).
