About this product

The Quietest SFX-L PSU Taking after the ROG Thor, the ROG Loki SFX-L 850W Platinum brandishes the same enthusiast-grade components and features, all packed into an SFX-L form factor. Boasting quiet operation and high performance, the Loki is primed to power your next SFF build. 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 The fan impeller spins on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design. 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.
