This article covers 静かに! ダークパワー13 750W 静音性能電源.

Overview

The be quiet! Dark Power 13 750W (BN659) is a flagship power supply that targets enthusiasts who refuse to compromise on silence. With 80 PLUS Titanium certification, it achieves up to 95.4% efficiency, meaning less wasted heat and lower electricity bills. This unit fully supports ATX 3.0 and PCIe 5.0, including a native 12VHPWR connector for modern graphics cards. Fully modular cabling and a 135mm Silent Wings 3 fan make it a breeze to build with. The 750W capacity comfortably handles mid-to-high-end gaming rigs, while the 10-year warranty offers long-term peace of mind.

Compatibility Guide

The Dark Power 13 adheres to the standard ATX form factor, measuring 175 × 150 × 86 mm. Its 175mm depth may be tight in smaller cases; ensure at least 180mm of clearance. Connectors include a main 24-pin ATX, dual CPU EPS 12V (4+4-pin), one PCIe 5.0 12VHPWR, four PCIe 6+2-pin, nine SATA, and four peripheral 4-pin. It’s ready for dual-GPU setups or high-end single-GPU configurations, though with 750W rated output, careful load balancing is advised for top-tier GPUs.

Product Info

Released in 2023, the Dark Power 13 750W sits at the high end of the market. It carries a 10-year warranty, underlining be quiet!'s confidence in its build quality. The unit uses an active rectifier plus full-bridge LLC topology for stable power delivery and high efficiency. An overclocking key lets you switch between four independent 12V rails or a single powerful rail—ideal for extreme overclocks. The frame-less Silent Wings 3 fan operates nearly silently at low loads and remains very quiet under full load.

Best Use Cases

This PSU is perfect for silent PC builds where fan noise must be minimized. Its low-speed fan curve and quality bearing ensure near-silent operation at idle. It’s also a great match for high-end gaming rigs using RTX 40-series or upcoming GPUs thanks to native 12VHPWR support. Finally, anyone looking for a long-term investment will appreciate the 10-year warranty and Japanese capacitors that promise reliability over many years. ## Alternatives
In the same premium tier, the Seasonic PRIME TX-750 and Corsair HX750i are strong competitors. The Seasonic also has Titanium efficiency but lacks a native 12VHPWR connector—you’ll need an adapter for modern GPUs. The Corsair HX750i offers iCUE software control for fan curves and monitoring, but its fan is a bit louder than the be quiet!'s. The be quiet! wins for pure silence and the unique OC key feature.

Things to Consider

750W is comfortable for mid-range builds but may be insufficient for an RTX 4090 or dual-GPU setups under sustained full load. If you plan to overclock a high-end CPU and GPU simultaneously, consider stepping up to the 850W or 1000W version. The included cables are somewhat stiff, making routing in tight cases a bit challenging. Additionally, the 12VHPWR connector has been reported to run warm under heavy loads; ensure it’s fully seated.
