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, ASUS has added a mirrored side panel that neatly frames the OLED display.

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

COOLING

ROG Heatsinks

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

Wing-blade Fan Design

A 135 mm Wing-blade fan with PWM control delivers lower noise and keeps thermals in check.

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.

0 dB Technology

To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 50% or below.​

Lambda A++ Certification

Thor II cooling upgrades result in a coveted Lambda A++ noise rating, confirming the latest iteration wields menacing power in absolute stealth.​

ENGINEERING

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.

EXPERIENCE

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