01 / 07ASUS ROG Thor 1200W Platinum III 80 Plus Platinum Fully Modular ATX 3.1 PSU
The ASUS ROG Thor 1200W Platinum III is an ATX 3.1-compliant flagship power supply engineered for high-end Intel and AMD gaming rigs running RTX 40/50-series and Radeon RX 7000/9000-series GPUs. GaN MOSFET technology delivers up to 30% greater power efficiency than conventional MOSFETs, while the patented GPU-First intelligent voltage stabilizer improves voltage delivery to the graphics card by up to 45% for rock-solid performance under variable GPU loads. A magnetic OLED display shows real-time power draw and rotates to suit fan-up or fan-down installations. Dual-ball-fan bearings, ROG heatsinks, and a fully aluminium enclosure keep thermals in check, all backed by a 10-year limited warranty.
Features
- GaN MOSFET Technology — Gallium nitride MOSFETs deliver up to 30% higher power efficiency than standard silicon MOSFETs and enable a more compact, better-cooled internal layout.
- GPU-First Voltage Stabilizer — Patented intelligent voltage stabilization improves power delivery to the graphics card by up to 45%, eliminating GPU voltage sag during frame-rate spikes.
- Magnetic OLED Display — A real-time power draw meter mounts magnetically and rotates freely to suit fan-up or fan-down PSU orientations without tools.
- ATX 3.1 Compliant — Full ATX 3.1 certification with Turbo Mode support handles extended power excursions from next-gen RTX and Radeon GPUs without triggering OCP.
- ROG Heatsinks & Aluminium Enclosure — Dedicated ROG heatsink blocks combined with a full-aluminium housing maximise thermal dissipation and keep internal temperatures low under sustained load.
- Dual-Ball-Fan Bearings — Two ball-bearing fans run up to twice as long as sleeve-bearing designs, with lower noise and greater resistance to heat-related degradation.
- 80 PLUS Platinum Certified — Low-ESR capacitors and premium components achieve Platinum-tier efficiency, reducing electricity costs and heat output across all load levels.
- 10-Year Warranty — ASUS backs every ROG Thor Platinum III with a decade-long limited warranty, the longest in the premium PSU segment.
