About the ASUS ROG Loki SFX-L 850W Power Supply Unit

Axial-tech Fan Design

Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For ASUS ROG Loki SFX-L 850W PSUs, that design is scaled to 120mm so it keeps things cool at low RPMs while producing less noise.

ROG Heatsinks

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

Dual Ball Fan Bearings

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

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

80 PLUS Platinum Certified

Low-ESR Japanese capacitors further improve efficiency and reduce heat, readying ASUS ROG Loki SFX-L 850W to reliably fuel your build for years to come.

Aura Sync

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

10-Year Warranty

ASUS are so confident about the reliability of the ASUS ROG Loki SFX-L 850W Platinum that they back it with a 10-year worldwide warranty.

ATX 3.0 Compatible

The latest power specification updates have landed. ATX 3.0 ushers in tighter voltage and current regulation guidelines for next-gen hardware – and ASUS ROG Loki SFX-L 850W 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.
