BE QUIET DARK POWER 14 850 W

No compromise silence and performance
Dark Power 14 850W features a high-performance heat sink design with an integrated fan and can be operated in either active or semi-passive mode.

Features
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

THE HIGHEST EFFICIENCY POSSIBLE
I am Titanium!
Dark Power 14 850W is certified with 80 PLUS Titanium and Cybenetics Titanium for a stunning energy efficiency rating of up to 95.6%. This provides lots of benefits for a high-end system, including less power consumption and an overall cooler and quieter operation.

NEXT GEN
With ATX 3.1 compatibility
Dark Power 14 850W 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.

PUSH THE BUTTON!
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
Simply fan-tastic
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
Maximum strength
Dark Power 14 850W 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 and the alternative massive single-rail operation.

PEAK TECHNOLOGY
Higher efficiency and lower ripple noise
Dark Power 14 1850W 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.

105C CAPACITORS FROM JAPAN
Just the best
Each component in Dark Power 14 850W is carefully selected. That is why we have exclusively used high-quality Japanese capacitors for this PSU. They are rated to 105C, ensure stability, reliability, and a long operating life.

PERFECTLY MODULAR
As all things should be
Modular, sleeved cables measuring up to 120cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling in even the largest PC cases.
