    ROG Loki 850W Platinum White Edition

    The Quietest SFX-L PSU

    Taking after the ROG Thor, the ROG Loki SFX-L 850W Platinum White Edition brandishes the same enthusiast-grade components and features, all packed into an SFX-L form factor. Boasting quiet operation and high performance, the Loki is primed to power your next SFF build.

    COOLING

    ROG Heatsinks

    Cool under pressure

    ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0 dB operation.

    Axial-tech Fan Design

    Better, faster, stronger

    Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For ROG Loki PSUs, ASUS has scaled that design to 120 mm, so it keeps things cool at low RPMs while producing less noise.

    Dual Ball Fan Bearings

    2x longer lifespan

    The fan impeller spins on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

    0 dB Technology

    Quiet intelligence

    To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 40% or below.

    Lambda A Certification

    Quietly deviant

    On average, ROG Loki emits less than 25 dB of noise – earning a coveted Cybenetics Lambda A certification.

    ENGINEERING

    80 PLUS Platinum Certified

    Effortless output



    Low-ESR Japanese capacitors further improve efficiency and reduce heat, readying ROG Loki to reliably fuel your build for years to come.

    ATX 3.0 Compatible

    Step into the future

    The latest power specification updates have landed. ATX 3.0 ushers in tighter voltage and current regulation guidelines for next-gen hardware – and ROG Loki steps ahead of the curve by being fully compliant. A 16-pin PCIe cable ripe for piping up to 600 W of power to PCIe® Gen 5.0 graphics cards is bundled with the PSU, bringing large-scale capabilities to SFF rigs.

    *Please be aware of specific instructions on the proper usage of this advanced 16-pin cable.

    EXPERIENCE

    ARGB-illuminated Fan & Aura Sync

    Magical glow

    The Loki's 120 mm fan features eight addressable LEDs ready to be customized with Aura Sync to create coordinated lighting patterns across your build.

    * If the connector cable is not used, the default color effect is rainbow.
    * To enjoy Aura Sync, you’ll need an Aura Sync-compatible ASUS or ROG motherboard. Similarly, the Smart Mode lighting effect, which reflects GPU temperature, requires use of a compatible ASUS or ROG graphics card.
