ASUS ROG Thor 1200W Platinum III ROG Equalizer PSU ATX 3.1
The ASUS ROG Thor 1200W Platinum III ROG Equalizer PSU ATX 3.1 is a high-output power supply built for gamers and enthusiasts who push their systems hard with overclocking, multi-GPU setups, or the latest GPU generations. It combines GaN MOSFET technology with a patented GPU-First intelligent voltage stabilizer to maintain rock-solid stability under demanding loads, and ships with the patented ROG Equalizer 12V-2x6 PCIe cable designed to reduce heat stress at the connector. A magnetic OLED display and AURA SYNC RGB round out a feature set aimed at builders who want both performance and visibility into their system.
Why this product
GaN MOSFET for improved efficiency
Next-generation GaN MOSFET technology boosts power conversion efficiency and reduces energy waste compared to conventional designs, contributing to the 80 PLUS Platinum rating.
GPU-First intelligent voltage stabilizer
A patented GPU-First voltage sensing circuit with intelligent stabilizer prioritizes stable voltage delivery to the graphics card, helping maintain consistent performance under heavy and fluctuating GPU loads.
ROG Equalizer cable reduces connector heat
The included patented ROG Equalizer 12V-2x6 PCIe power cable is engineered to distribute current more evenly, keeping cable and connector temperatures lower to protect the graphics card.
ATX 3.1 and PCIe 5.1 ready
Full ATX 3.1 compliance and PCIe 5.1 compatibility mean it is ready for current and forthcoming high-power GPU platforms, including GeForce RTX 50 and Radeon RX 9000 series cards.
Magnetic OLED display, both orientations
The OLED panel attaches magnetically and can be swapped to either side, supporting both fan-up and fan-down case installations without tools.
10-year warranty
ASUS backs this unit with a 10-year warranty, one of the longer coverage periods available in the enthusiast PSU segment.

Best for
- High-end GPU builds: The 1200 W output and PCIe 5.1 / 12V-2x6 connector support accommodate the power requirements of top-tier current-generation graphics cards.
- Overclockers and demanding workloads: Turbo Mode maximizes fan cooling during overclocking sessions or sustained heavy compute loads.
- Builders who prioritize voltage stability: The patented GPU-First intelligent voltage stabilizer addresses voltage fluctuation that can affect GPU performance under transient loads.
- Long-term ownership: A 10-year warranty and Cybenetics Platinum / Lambda A++ certifications reflect an expectation of extended, efficient operation.
- RGB-integrated systems: AURA SYNC and the OLED display suit builders assembling visually themed rigs with other ASUS ROG components.
Trade-offs
- Compact or small-form-factor builds: At 190 × 150 × 86 mm and ATX format only, it will not fit SFX or SFX-L cases.
- Budget-conscious builds: The feature set — GaN MOSFET, OLED display, ROG Equalizer cable, AURA SYNC — is aimed at enthusiast systems where those additions are valued.
- Low-power or entry-level systems: At 1200 W total output, this unit is oversized for builds with modest CPU and GPU power draws.
- Regions without 100–240 V infrastructure: Input range is specified as 100–240 V AC; installations outside this range are not supported.
