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.

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 3.1 Compatible

Step into the future

The latest power specification updates have landed. ATX 3.1 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 5.1 graphics cards is bundled with the PSU, bringing large-scale capabilities to SFF rigs.
