Our Take

Best for: Enthusiasts building high-end gaming or workstation PCs.

The ASUS ROG Thor 1000W Platinum III is a top-tier power supply built for high-end systems. Its GaN MOSFET design delivers superior efficiency and cooler operation compared to traditional silicon MOSFETs. The GPU-First intelligent voltage stabilizer ensures clean, stable power to your graphics card, reducing ripple and improving overclocking headroom. The magnetic OLED display is a nice touch for monitoring real-time power draw, and it can be repositioned to suit your build layout. Build quality is excellent with ROG heatsinks and an aluminum enclosure, plus dual-ball bearings for long fan life. It's fully modular with etched cables that are easy to route. The 10-year warranty reflects ASUS's confidence. 1 certified, it handles transient loads from high-end GPUs without issue. The main tradeoff is the price. This is a premium PSU, and you pay a premium for the ROG branding and features like the OLED display. If you don't need the visual flair or GaN efficiency, there are cheaper 1000W Platinum units. But for a no-compromise build, this PSU delivers.

Price Analysis

At $349.99, this is 16% off the original $417.99. While not the deepest discount, it's a solid price for a newly released flagship PSU. The 10-year warranty adds long-term value. Given its premium features and performance, this is a good time to buy for those who want top-tier components.
