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.
