    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 12V-2x6 connector 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 850W. 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 850W 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.

    105°C 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 105°C, 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.

    The be quiet! Dark Power 14 is a modular 850W ATX 3.1 power supply for high-performance gaming PCs and workstations using PCIe 5.1 graphics cards. It combines 80 PLUS Titanium efficiency with selectable active or semi-passive cooling, making it a fit for builders who want high-efficiency power and quiet operation.

    Recommended For

    • Quiet-focused desktop builders who want a PSU that can stop its fan at light loads and choose active or semi-passive cooling.
    • Builders of modern gaming or workstation desktops whose component power requirements fit within 850W and who want an ATX 3.1 PSU with a native PCIe 5.1 GPU power connection.
    • Efficiency-conscious desktop users who expect long periods of operation and value Titanium-rated efficiency alongside independently tested efficiency results.
    • Enthusiast builders who plan to tune or overclock a compatible desktop and want the Dark Power 14’s overclocking-focused features and selectable rail mode.

    Real-World Use Scenarios

    • Building a quiet gaming PC? Select semi-passive mode for everyday desktop use so the PSU fan can stay off at low loads; during demanding games, the fan starts when additional cooling is needed.
    • Connecting a compatible newer graphics card? Use the PSU’s native 12V-2x6 cable for a direct power connection, while checking that the whole PC’s power needs fit within an 850W supply.
    • Upgrading a PC with a graphics card that uses conventional PCIe power plugs? The included 6+2-pin connections let the PSU serve many builds using those connectors as well as compatible newer-card setups.
    • Running games or creator applications that put sustained demand on the system? The selectable active-cooling mode keeps the PSU fan running, while semi-passive mode lets it stop at low loads; choose based on your preferred cooling behavior.
    • Assembling a high-end PC with several storage drives or accessories? Its modular cabling lets you connect the leads the build needs and leave unused PSU cables out of the case, helping keep the build easier to route.
