COOLING | 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 20 dB of noise - earning a coveted Cybenetics Lambda A+ certification.
ENGINEERING | 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.
EXPERIENCE | 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.
