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
Dual ball bearings boast a remarkable lifespan of 80,000 hours, lasting twice as long as sleeve bearings and exceeding even fluid dynamic bearings. Ensuring long-lasting, reliable cooling with minimal noise for ROG Loki SFX-L series.
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.
ENGINEERING
High-performance Copper Pins
Upgraded PCIe® connectors featuring superior thermal conductivity ensure cooler operation and improved power delivery efficiency. This translates to a significant 29% reduction in connector temperatures (up to -12.28°C), promoting optimal performance and stability for even the most demanding graphics cards.
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.
[Graphics Card & PSU] How to plug in the 16-pin power cable properly
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.
* 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.

Video Reviews
Those who follow me know that I am a die-hard micro ATX fan, and this video is dedicated to that. The build behind me is atomic cool and beautiful, this is a total white ASUS configuration. ASUS PRIME AP201 is the absolute star of this video, it is very interesting because very few cases of this format come out and this one, while not costing a lot lends itself to builds of a certain level.
