The Quietest 1000W Power Supply Back with a vengeance, the second iteration of the ROG Thor 1000W 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. ROG Heatsinks ROG heatsinks have 2x more volume than traditional designs, facilitating lower temperatures, longer component lifespan, and extended 0dB operation. Axial-tech Fan Design A 135mm Axial-tech 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 Certification80 Plus Platinum Certification The ROG Thor 1000W 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.
