1600W ATX 3.0 power supply

The be quiet! Dark Power PRO 13 BN501 delivers 1600 W of continuous power for extreme workstations and multi-GPU rigs. It meets the ATX 3.0 specification and carries 80 PLUS Titanium certification at up to 94.5 percent efficiency. Six 12 V rails can be merged into a single rail using the overclocking key. Modular individually sleeved cables keep the build tidy.

Sustained-load behaviour

Fully digital control with Active Rectifier and full bridge LLC topology maintains tight voltage regulation during prolonged heavy draw. The 135 mm Silent Wings frameless fan stays virtually inaudible at ordinary loads while providing enough airflow for continuous 1600 W operation. Over-voltage and overload protection circuits guard components during extended stress sessions. Standby power draw remains below .1 W.

ATX 3.0 practical limits

The unit supplies six PCIe 6+2 pin connectors and sixteen SATA power connectors for dense drive arrays. Main power uses a 20+4 pin connector compatible with current motherboards. Input range covers 100 to 240 V at 50 or 60 Hz with active PFC. Physical depth is 200 mm, so case clearance must be verified before installation.

Questions about this item

How loud and hot does the 135 mm Silent Wings fan get when the 1600 W unit runs all day?

The patented frameless fan is designed for virtually inaudible operation at ordinary loads, and 80 PLUS Titanium efficiency up to 94.5 % reduces waste heat, keeping temperatures lower during continuous use.

Which cables and motherboard connectors must I already have to install this fully modular ATX 3.0 power supply?

You need a motherboard with a 20+4 pin main socket, plus your own PCIe 5.0 or 6+2 pin GPU cables, SATA drives for the 16 SATA power plugs, and a case that fits a 200 mm deep unit.

Will the six 12 V rails or the single-rail overclocking mode work safely with my older graphics cards and drives?

The overclocking key lets you choose six 12 V rails for multi-GPU legacy setups or one massive 12 V rail for modern cards, while 16 SATA and six 6+2 pin PCIe connectors cover both old and new peripherals.
