Why SFX-L Matters for Your Build

SFX-L power supplies offer a sweet spot between compact SFX and standard ATX dimensions. The ROG Loki’s 125×125×63.5 mm footprint fits standard SFX-L cases while providing the 1200W capacity typically found in larger units. This means you can build a powerful, space-efficient system without compromising on component selection or cooling performance.

Cooling That Won’t Drown Out Your System

ROG heatsinks and dual ball fan bearings work together to keep temperatures low and noise minimal. The PWM-controlled fan features 0dB technology, shutting off completely when system load drops below 40%. This intelligent cooling design, combined with Cybenetics Lambda Standard ++ certification (under 35 dB average noise), ensures whisper-quiet operation during everyday tasks while maintaining excellent thermal performance under heavy loads.

Future-Proof Power Delivery

ATX 3.1 compatibility means this PSU meets the latest power specification standards, with tighter voltage and current regulation for next-generation hardware. The included 16-pin PCIe cable supports up to 600W delivery to PCIe Gen 5.0 graphics cards, bringing desktop-class power capabilities to your small form factor build. Low-ESR Japanese capacitors enhance efficiency and reliability for years of dependable service.

Customisable Lighting with Aura Sync

The 120mm fan features eight addressable RGB LEDs that integrate seamlessly with Aura Sync ecosystem. When connected to compatible ASUS or ROG motherboards, you can create coordinated lighting effects across your entire build. The Smart Mode even reflects GPU temperature through lighting changes, adding both style and functional monitoring to your system.
