ASUS ROG THOR 850W Platinum II power supply unit 20+4 pin ATX Black, Blue, Grey by ASUS

The Quietest 850W Platinum Power Supply
Back with a vengeance, the second iteration of the ROG Thor 850W Platinum wields cooling and component upgrades that make it the quietest PSU in its class*. And to compliment the latest high-end ROG motherboards and bring additional flair to beastly rigs, we've added a mirrored side panel that neatly frames the OLED display.

Based on Cybenetics PSU test result database entries before October 2021.

ROG Heatsinks
ROG heatsinks have 2x more volume than traditional designs, facilitating lower temperatures, longer component lifespan, and extended 0dB operation.

80 Plus Platinum Certification
The ROG Thor 850W Platinum II utilizes low-ESR Japanese capacitors to ensure efficient operation. These upgrades enable an 80 PLUS Platinum certification, which guarantees 89% efficiency at 100% load and 92% efficiency at 50% load. The increased efficiency results in less heat, reduces fan noise, and increases reliability.

OLED Power Display
The built-in OLED panel makes it easy to tune your system for best performance and efficiency.
