  • Be Quiet! Pure Power 12 M 850W EPS12V, ATX Modular Power Supply

    BN344

    80 PLUS® GOLD CERTIFIED
    Very high operating efficiency
    Pure Power 12 M 850W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 93.2%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 12 M 850W is always the correct choice for quiet systems and gaming PCs!

    FUTURE-PROOF YOUR SYSTEM
    Fulfills all ATX 3.0 specifications
    Pure Power 12 M 850W is an ATX 3.0 PSU and comes with both native integration of the 12VHPWR connector for next-generation PCIe 5.0 graphics cards, and PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and the perfect choice for powerful systems of today and the ones to come.

    THE NEW STANDARD OF POWER
    For massive transient loads
    Pure Power 12 M offers 850W of continuous power with 2 independent 12V rails. Even if the graphics card demands excessive power for a short time: Pure Power 12 M 850W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.

    UNPRECEDENTED SILENT OPERATION
    Achieved with a silence-optimized be quiet! fan
    The exceptionally silent 120mm be quiet! fan is temperature-controlled to strike the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, enabling best-in-class
    quiet functionality.

    HIGH-CLASS TECHNOLOGIES
    Rock-solid stability
    With its LLC topology Pure Power 12 M 850W provides a best-in-class voltage regulation and efficiency. That makes it perfect for building or upgrading very quiet systems as well as gaming and media creation PCs.

    MODULAR CABLES
    Utmost convenience and compatibility
    Thanks to their modularity, all unnecessary cables in the system are left out. Pure Power 12 M 850W simplifies cable management and routing for a tidy-looking system. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures inside the case.
