High-wattage ATX 3.0 power supply

The be quiet! Dark Power PRO 13 1300W BN500 delivers up to 1300 W of continuous power for high-end desktop systems. It meets the ATX 3.0 specification and carries 80 PLUS Titanium certification at up to 94.4 percent efficiency. The unit targets enthusiasts building workstations or multi-GPU rigs that demand stable, high-current output.

Fully modular design with Silent Wings fan

An aluminium chassis houses a 135 mm frameless Silent Wings fan optimised for low noise at typical loads. All cables are individually sleeved and fully modular, so only the required leads are installed. The main 20+4 pin connector, six PCIe 6+2 pin plugs and sixteen SATA power connectors cover a wide range of components. An overclocking key on the rear panel switches the +12 V output between six independent rails and a single massive rail.

ATX 3.0 limits and protection features

The power supply handles massive power excursions as defined by the ATX 3.0 standard, protecting components during transient spikes. Fully digital control with Active Rectifier and Full Bridge LLC topology keeps voltage regulation tight across all rails. Over-voltage and overload protection circuits shut the unit down safely if limits are exceeded. Universal input from 100 to 240 V at 50 or 60 Hz allows worldwide operation without a voltage switch.
