ROG Loki SFX-L 850W Platinum power supply (fully modular power supply, 80+ Platinum, Lambda A certified, 120mm PWM ARGB fan, Aura Sync RGB lighting, ATX 3.0 compatible, PCIe 5.0 ready, white)

The Quietest SFX-L PSU
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.


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.

* 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 Warranty
A decade of power
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.
*Core product operation is guaranteed for 10 years. The RGB LEDs are subject to a 3-year warranty.
