Axial-tech Fan Design

Better, faster, stronger

ROG Loki 850W 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 ROG Loki 850W 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

Thor II cooling upgrades result in a coveted Lambda A++ noise rating, confirming the latest iteration wields menacing power in absolute stealth.

80 PLUS Platinum Certified

Effortless output

Low-ESR Japanese capacitors further improve efficiency and reduce heat, readying ROG Loki 850W 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 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.

ARGB-illuminated Fan & Aura Sync

Magic glow

The ROG Loki 850W’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.​
