be quiet! Dark Power 13 1000W ATX 3.0 power supply BN661

1000 W ATX 3.0 power supply

The Dark Power 13 BN661 delivers 1000 W of continuous power with 80 PLUS Titanium efficiency up to 95.2 percent. It meets ATX 3.0 specifications and supports PCIe 5.0 graphics cards through four 6+2 pin connectors. A frameless Silent Wings fan and full-mesh front panel keep noise to a minimum. The unit is fully modular for clean cable routing.

Check ATX 3.0 readiness and cable needs

Verify that your motherboard accepts the 20+4 pin main connector and that the case can fit a 175 mm deep unit. Ensure the four 6+2 pin PCIe cables match your graphics card requirements and count the 13 SATA connectors against your drive count. The overclocking key lets you choose between four 12 V rails or a single 12 V rail before installation. Input voltage covers 100 to 240 V at 50 or 60 Hz.

Sustained-load behaviour and protection

At full load the Titanium-rated design keeps waste heat low, helping the fan stay near its quietest speed. Active rectifier plus full-bridge LLC topology maintains tight voltage regulation on the 12 V, 5 V and 3.3 V rails during long sessions. Over-voltage and overload protection circuits engage if limits are exceeded. Standby power draw remains below 0.1 W when the system is off.
