ROG Heatsinks

Cool and Consistent
ROG-engineered heatsinks keep critical components cooler, improving longevity and extending 0dB operation during light workloads.

Axial-Tech Fan Design

Efficient, Powerful, Quiet
A smaller fan hub allows for longer blades and a barrier ring to maximize downward air pressure. The specially-tuned 120mm fan keeps the PSU cool while minimizing noise.

Dual Ball Fan Bearings

Built to Last
The durable fan spins on dual ball bearings, offering up to twice the lifespan of traditional sleeve bearing fans.

0dB Technology

Silent When You Need It
When system load is below 40%, the fan shuts off entirely for silent operation, resuming only when additional cooling is required.

80 PLUS Platinum Certified

Efficient Power Delivery
Premium low-ESR Japanese capacitors enhance efficiency and minimize heat, helping ROG Loki deliver consistent power for years of dependable use.

ARGB Fan with Aura Sync

Customizable Lighting
Eight addressable LEDs within the 120mm fan are fully compatible with Aura Sync, allowing you to synchronize lighting effects across your gaming setup.

Note: Without the connector cable, the fan defaults to a rainbow effect. Aura Sync compatibility requires an ASUS or ROG motherboard. Smart Mode (GPU temperature-based lighting) requires a compatible ASUS or ROG graphics card.

10-Year Warranty

A Decade of Reliability
We stand by the ROG Loki SFX-L 850W Platinum with a 10-year global warranty for core components. (RGB LEDs are covered by a separate 3-year warranty.)
