Key Features
- Dark Power 14 1200W is certified with 80 PLUS Titanium and Cybenetics Titanium for a stunning energy efficiency rating of up to 95.42%. This provides lots of benefits for a high-end system, including less power consumption and an overall cooler and quieter operation.
- Dark Power 14 1200W is an ATX 3.1 PSU and comes with both native integration of the two 12V-2x6 connectors for next-generation PCIe 5.1 graphics cards and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and perfect for current and future high-end systems.
- A button on the rear of the power supply allows switching between a balanced active cooling mode, where the Silent Wings fan spins all the time, or a semi-passive mode, where the fan does not spin under low load and only starts when additional cooling is required for more demanding operations. A post-ventilation setting keeps the fan spinning after cooling down for a short period of 2–5 minutes to prevent frequent and noisy starts and stops.
- A large heat sink connects to the parts of the power supply that need the most cooling and dissipates a large portion of the heat. Even though a Titanium efficiency power supply does not generate as much heat, active cooling is required to prevent overheating issues under high load. Nothing less than the very best fan of be quiet! cools Dark Power 14 1200W. Being integrated directly into the heat sink, this high-end fan is immune to vibrations and sits unshakably. A 6-pole fan motor and fluid-dynamic bearing ultimately make for exceptionally long lifetime and minimal power consumption.
- Dark Power 14 1200W is particularly suitable for overclocking. With the simple push of a button, you can manually switch between multi-rail and single-rail mode. This gives you full overclocking control between the default four 12V-rail mode and the alternative massive single-rail operation.
- Dark Power 14 1200W is state-of-the-art technology. With an Active Rectifier and full bridge LLC technology it offers some of the most advanced technologies available, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation.
