The Quietest SFX-L PSUTaking 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.COOLINGROG HeatsinksCool under pressureROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.Axial-tech Fan DesignBetter, faster, strongerAxial-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, we've scaled that design to 120mm so it keeps things cool at low RPMs while producing less noise.Dual Ball Fan Bearings2x longer lifespanThe fan impeller spins on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.0dB TechnologyQuiet intelligenceTo reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 40% or below.Lambda A CertificationQuietly deviantOn average, ROG Loki emits less than 25 dB of noise earning a coveted Cybenetics Lambda A certification.ENGINEERING80 PLUS Platinum CertifiedEffortless outputLow-ESR Japanese capacitors further improve efficiency and reduce heat, readying ROG Loki to reliably fuel your build for years to come.ATX 3.0 CompatibleStep into the futureThe 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 600W of power to PCIe Gen 5.0 graphics cards is bundled with the PSU, bringing large-scale capabilities to SFF rigs.EXPERIENCEARGB-illuminated Fan & Aura SyncMagical glowThe 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.10-Year WarrantyA decade of powerWe're so confident about the reliability of the ROG Loki SFX-L 850W Platinum White Edition that we back it with a 10-year worldwide warranty.*Core product operation is guaranteed for 10 years. The RGB LEDs are subject to a 3-year warranty.
