ASUS ROG Loki SFX-L 850W Platinum Power Supply Unit 24-pin ATX - 90YE00N3-B0NA00

The Quietest SFX-L PSU

Taking after the ROG Thor, the ROG Loki SFX-L 850W Platinum 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.

ROG Heatsinks: Cool under pressure

ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB 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, we've scaled that design to 120mm 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.

0dB 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.

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 600W of power to PCIe Gen 5.0 graphics cards is bundled with the PSU, bringing large-scale capabilities to SFF rigs.

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.
