Specifications

GaN MOSFET Technology for Next-Gen Efficiency

The ROG Thor 1200W Platinum III features a GaN (Gallium Nitride) MOSFET that delivers superior efficiency compared to traditional silicon designs. This advanced semiconductor technology reduces heat generation and power loss, enabling the PSU to maintain peak performance under heavy loads. For UK gamers building systems with multiple high-end GPUs or running demanding creative workloads, this efficiency translates to lower electricity costs and cooler operation.

“GPU-First” Intelligent Voltage Stabilisation

ASUS’s patented “GPU-First” voltage sensing technology actively monitors and stabilises power delivery to your graphics card before other components. This intelligent voltage stabilizer ensures your GPU receives clean, consistent power even during intense gaming sessions or when overclocking. The system automatically prioritises graphics card stability, preventing voltage fluctuations that could cause crashes or performance drops during critical moments.

Magnetic OLED Display with Side-Swap Flexibility

The signature Thor OLED display has been upgraded with a magnetic attachment system, allowing you to position it on either side of the PSU. This flexibility accommodates both fan-up and fan-down mounting orientations in your PC case. The display shows real-time power draw, helping you monitor system consumption and identify potential bottlenecks. The magnetic design also makes it easy to remove for cleaning or repositioning without tools.

Turbo Mode for Maximum Cooling Performance

When your system demands maximum cooling—whether during overclocking sessions or extended gaming marathons—Turbo Mode increases fan speed for enhanced heat dissipation. This feature activates automatically when the PSU detects high thermal loads, ensuring optimal temperatures without constant manual adjustment. The 120,000-hour MTBF bearing technology ensures reliable, quiet operation even under sustained Turbo Mode usage.
