be quiet! Dark Power 14 1200 W - 80 Plus Titanium power supply unit 20+4 pin ATX ATX Black BP021EU

Dark Power 14 1200W features a high-performance heat sink design with an integrated fan and can be operated in ei... morether active or semi-passive mode. - 80 PLUS® Titanium and Cybenetics Titanium efficiency (up to 95.42 %) - ATX 3.1 PSU with full support for PCIe 5.1 GPUs and GPUs with 6+2-pin connector - Active and semi-passive cooling can be selected with the push of a button - Aluminum heat sink to support the semi-passive cooling concept and improve longevity of the components - Silent Wings fan for virtually inaudible operation - Full bridge + Synchronous Rectifier + LLC technology provides unmatched signal stability and extremely high efficiency       I am Titanium! Dark Power 14 1200W is certified with 80 PLUS® Titanium and Cybenetics Titanium for a stunning energy efficiency rating of up to 95.4%. This provides lots of benefits for a high-end system including less power consumption and an overall cooler and quieter operation.         With ATX 3.1 Compatibility 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.       Switch Effortlessly Between Active and Semi-Passive Cooling 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.     Heat Sink and Integrated Silent Wings   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.     Ready for Overclocking   Dark Power 14 1200W is particularly suitable for overclocking. With the simple push of a button it is possible to manually switch between multi-rail and single-rail mode. This gives full overclocking control between the default four 12V-rail mode
