ASUS ROG-THOR-1200P3-GAMING 1200W Platinum III power supply

High-wattage PSU for demanding builds

The ASUS ROG Thor 1200W Platinum III is a 1200 W ATX 3.1 power supply built for systems that draw heavy, sustained loads. It targets enthusiasts who need headroom for high-end graphics cards and multi-core processors. Buyers who want more storage or additional expansion cards should verify their own platform limits, as this unit only supplies power.

1200 W capacity with Platinum efficiency

At 1200 W the unit comfortably handles modern flagship GPUs and overclocked CPUs together. The 80 PLUS PLATINUM Certified rating means up to 30% more power efficiency than standard designs, reducing waste heat. GaN MOSFETs contribute to a more organized internal layout. Where it runs out is any configuration that exceeds the 1200 W maximum power rating.

Thermals, noise and power draw in normal use

ROG heatsinks and a fully aluminum enclosure synergize for superior cooling, keeping system thermals under control. Dual-ball-fan bearings can last up to twice as long as sleeve bearing designs, supporting quieter long-term operation. Turbo Mode uses a fine-tuned fan curve to unlock support for extended power excursions. The magnetic OLED display shows real-time power draw and can be swapped to either side for fan-up or fan-down installation.
