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.

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.

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

The ROG Thor 850W Platinum II is backed with a 10-year warranty.
