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.
Experience
Etched Cables
Made from a soft premium material, these etched cables can be bent easily during installation, and they operate at temperatures 50°C lower than the safety limit when bent for cable management. These cables also meet the rigorous standards of the UL1581 flame test and UL758 certification, helping to ensure a smooth PC DIY experience and exceptional safety.
ARGB-Illuminated Fan & Aura Sync - Magical Glow
The Loki's 120 mm fan features eight addressable LEDs ready to be customised with Aura Sync to create coordinated lighting patterns across your build.
* If the connector cable is not used, the default colour 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.
