The Quietest SFX-L PSU<br>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.<br><br>COOLING<br><br><b>ROG Heatsinks</b><br>Cool under pressure<br>ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.<br><br><b>Axial-tech Fan Design</b><br>Better, faster, stronger<br>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, we've scaled that design to 120mm so it keeps things cool at low RPMs while producing less noise.<br><br><b>Dual Ball Fan Bearings</b><br>2x longer lifespan<br>The fan impeller spins on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.<br><br><b>0dB Technology</b><br>Quiet intelligence<br>To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 40% or below.<br><br><b>Lambda A Certification</b><br>Quietly deviant<br>On average, ROG Loki emits less than 25 dB of noise – earning a coveted Cybenetics Lambda A certification.<br><br>ENGINEERING<br><br><b>80 PLUS Platinum Certified</b><br>Effortless output<br>Low-ESR Japanese capacitors further improve efficiency and reduce heat, readying ROG Loki to reliably fuel your build for years to come.<br><br><b>ATX 3.0 Compatible</b><br>Step into the future<br>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 600W of power to PCIe Gen 5.0 graphics cards is bundled with the PSU, bringing large-scale capabilities to SFF rigs.<br><br>EXPERIENCE<br><br><b>ARGB-illuminated Fan & Aura Sync</b><br>Magical glow<br>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.<br><br>* If the connector cable is not used, the default color effect is rainbow.<br>* 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.<br><br><b>10-Year Warranty</b><br>A decade of power<br>We'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.<br>*Core product operation is guaranteed for 10 years.
