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.

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. 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. 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. 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.

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.
