The Quietest SFX-L PSU Taking after the ROG Thor, the ROG Loki SFX-L 850W Platinum White Edition 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 ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation. 80 PLUS Platinum Certified Low-ESR Japanese capacitors further improve efficiency and reduce heat, readying ROG Loki to reliably fuel your build for years to come. Magical glow The Loki's 120 mm fan features eight addressable LEDs ready to be customized with Aura Sync to create coordinated lighting patterns across your build. * If the connector cable is not used, the default color effect is rainbow. * To enjoy Aura Sync, you’ll need an Aura Sync-compatible ASUS or ROG motherboard. Similarly, the Smart Mode lighting effect, which reflects GPU temperature, requires use of a compatible ASUS or ROG graphics card. Axial-tech Fan Design Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. Dual Ball Fan Bearings 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 To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 40% or below. Lambda A Certification On average, ROG Loki emits less than 25 dB of noise – earning a coveted Cybenetics Lambda A certification.
