The ROG Loki 850W Platinum, reminiscent of the ROG Thoria, offers the same high-quality components and features packed into an SFX-L form factor. Providing low noise levels and high performance, the Loki is perfect for your next small form factor build.

• ROG cooling fins protect vital components. Lower temperatures extend component lifespan and reduce overall system noise.
• Axial-tech cooling: A 120 mm PWM-controlled fan keeps heat and noise in check.
• ATX 3.0 compatible: The ROG Loki complies with ATX 3.0 guidelines. It also includes a 16-pin PCIe cable capable of delivering up to 600 W to PCIe Gen 5.0 graphics cards.
• Lambda A+ certification: Certified low noise level, under 25 dB.
• 80 PLUS Platinum certified: Up to 92% efficiency ensures low heat and noise levels while improving reliability.
• Aura Sync compatible: Ready for synchronized lighting effects across your gaming setup.

ROG cooling fins – Keep cool under pressure
ROG cooling fins enable low operating temperatures, long component lifespan, and silent operation.

Axial-tech fan design – Better, faster, stronger
The Axial-tech fan design features a smaller hub allowing longer blades and a frame that increases downward air pressure. In ROG Loki power supplies, this design is scaled to 120 mm, effectively cooling hardware while reducing noise through lower fan speeds.

Dual ball bearing fan – Twice the lifespan
The dual ball bearing fans last up to twice as long as sleeve bearing fans.

Silent technology – Quiet power
To reduce noise, the PWM-controlled fan only starts spinning when the power supply load exceeds 40 percent.

Lambda A+ certification – Exceptionally quiet
The ROG Loki’s noise level averages under 20 dB, earning the coveted Cybenetics Lambda A+ certification.

80 PLUS Platinum certified – Effortless power delivery
Japanese low-ESR capacitors improve efficiency and reduce heat generation, enabling the ROG Loki to reliably serve your build for years.

ATX 3.0 compatible – Step into the future
The latest power supply standard updates are here. ATX 3.0 sets stricter voltage and power regulation requirements for next-generation devices—and the forward-looking ROG Loki meets them all. The included 16-pin PCIe cable is ready to deliver up to 600 W to PCIe Gen 5.0 graphics cards, bringing high performance to small form factor PCs.

ARGB-lit fan and Aura Sync – Magical glow
The Loki’s 120 mm fan features eight addressable LEDs that can be synchronized across your setup with Aura Sync.
(*If the connector cable is not in use, the default lighting effect is rainbow. Aura Sync requires a compatible ASUS or ROG motherboard. Similarly, the Smart Mode lighting that changes with GPU temperature requires a compatible ASUS or ROG graphics card.)

10-year warranty – Power for a decade
Asus is so confident in the durability of the ROG Loki SFX-L 850W Platinum that it offers a 10-year worldwide warranty.
