Exceptional Efficiency and Acoustic Performance

Certified for 80 PLUS Gold efficiency and Cybenetics Platinum rating, the Steel Legend SL-850GW maintains high energy conversion rates across all load levels. The Cybenetics Lambda A+ acoustic certification confirms operation at less than 20 dB average noise, making this one of the quietest power supplies in its class.

iCOOL Intelligent Fan Control

The 135mm striped axial fluid dynamic bearing fan features iCOOL intelligent fan control with a physical switch. In iCOOL mode, the fan remains off during low to medium loads for silent operation, only activating when needed. Disable iCOOL mode for continuous cooling under sustained heavy loads. The fluid seal design and herringbone structure ensure minimal noise and extended lifespan.
