Engineering

GaN MOSFET
The ROG Thor 1000W Platinum III PSU boasts an innovative GaN MOSFET that deliver up to 30% more power efficiency than standard MOSFETs. Plus, the smaller size of a GaN MOSFET allows for a more organised internal layout. This optimised design provides space for larger heatsinks and enhanced airflow, improving heat dissipation.
Intelligent Voltage Stabiliser - "GPU-First" Voltage Sensing with Patented Intelligent Voltage Stabiliser (IVS)
Activate the "GPU-First" voltage sensing by connecting the IVS cable. This innovative feature enhances voltage stability by up to 45%, even during demanding gaming sessions and overclocking scenarios. If you prefer conventional CPU-focused voltage sensing, simply disconnect the IVS cable. With this advanced technology, you can experience smooth and consistent gaming.

High-Performance Copper Pins
Upgraded PCIe® connectors feature superior thermal conductivity to help ensure cooler operation and improved power delivery efficiency. This translates to a significant 29% reduction in connector temperatures (up to 12.3°C), promoting optimal performance and stability for even the most demanding graphics cards.

ATX 3.1 Compatible
ATX 3.1 ushers in tighter voltage and current regulation standard for next-gen hardware - and the ROG Thor 1000W Platinum III arrives ahead of the curve with full compliance. A 16-pin PCIe cable capable of sending up to 600 watts of power to PCIe 5.0 graphics cards is bundled with this PSU, readying your build for the next gen.
80 Plus Platinum Certification
The ROG Thor 1000W Platinum III utilises low-ESR Japanese capacitors to ensure efficient operation. These upgrades enable 80 PLUS Platinum certification, which guarantees 89% efficiency at 100% load and 92% efficiency at 50% load. The increased efficiency results in less heat, reduced fan noise, and increased reliability.
Cooling

ROG Heatsinks - Cool Under Pressure
ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.

Dual-Ball-Fan Bearings - 2X Longer Lifespan
Dual-ball bearings boast a remarkable lifespan of up to 80,000 hours, twice as long as sleeve bearings and exceeding even fluid dynamic bearings. This helps to ensure long-lasting and reliable cooling with minimal noise for the ROG Thor 1000W Platinum III.
*Illustration for reference only.
0dB Technology - Quiet Intelligence
To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is at 30% or below.
In 0dB mode (button pressed), the fan continues to spin when transitioning from high to low loads, ensuring safe temperatures are reached before stopping.
Experience
Magnetic OLED Display
This detachable magnetic OLED display showcases real-time power draw, providing insights to your system's performance and efficiency. The magnetic attachment can be swapped to either side of the unit for fan-up or fan-down PSU installation, depending on the design of your case, so you can maintain optimal airflow without compromising monitoring.
Turbo Mode
Turbo Mode unlocks support for extended power excursions, courtesy of a fine-tuned fan curve and premium components. Enjoy unwavering performance when you need it most, and switch between
