ROG Thor 850W Platinum II is the quietest PSU in its class.

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. For more information, please refer to here.

COOLING

ROG Heatsinks

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

Wing-blade Fan Design

A 135mm 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.

0dB 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

OLED Power Display

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

Aura Sync

Customize the Aura ROG logo and/or add RGB lighting strips to accent your showcase 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.

Sleeved Cables

A range of sleeved cables are bundled with Thor II, and we also provide a 20% CableMod discount.

PCIe Gen 5.0 Ready

Each ROG Thor 850W Platinum II PSU is bundled with a 16-pin PCIe cable that can pipe up to 600W of power to PCIe Gen 5.0 graphics cards. Get ready for the future of power delivery.

10-year Warranty
