ROG Loki 850W Platinum
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.

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.
