be quiet! Dark Power 13 750W ATX 3.0 power supply BN659

German engineering for high-end builds

The be quiet! Dark Power 13 750W is an ATX 3.0 power supply built for systems that demand 80 PLUS Titanium efficiency and native PCIe 5.0 support. Its fully modular design and four 12V rails deliver clean power to modern graphics cards and storage arrays. The 175 mm depth fits standard ATX cases while the single fan keeps airflow focused.

Upgrade from lower efficiency or ATX 2.x units

Moving from an 80 PLUS Gold or Platinum design to this Titanium-rated model cuts waste heat and lowers standby draw below 0.1 watts. The jump is worth it when a new GPU requires the 12VHPWR connector or when overclocking demands the stability of Active Rectifier plus full bridge LLC topology. Four 6+2 pin PCIe connectors also cover current-generation cards without adapters.

Sustained load behaviour

Under continuous demand the unit maintains up to 95.8% efficiency thanks to digital control and the overclocking key that merges four 12V rails into one massive rail. Over-voltage and overload protection engage automatically while the frameless Silent Wings fan spins only as fast as thermals require. MTBF exceeds 100,000 hours at 50/60 Hz input across 100-240 V.
