ASUS ROG Thor 1200W Platinum III ATX 3.1 Fully Modular Power Supply with OLED Display - 90YE00V7-B0NA00

The ASUS ROG Thor 1200W Platinum III is a flagship ATX 3.1 power supply built around a next-generation GaN MOSFET for higher efficiency and a patented GPU-First intelligent voltage stabiliser for rock-solid delivery under load. Its signature OLED display now attaches magnetically and can be moved to either side, supporting both fan-up and fan-down installation. The bundled ROG Equalizer 12V-2x6 cable is engineered to even out current distribution and keep connector temperatures down.

GaN MOSFET and GPU-First Stabilisation

A next-generation GaN MOSFET improves switching efficiency over conventional silicon, cutting energy waste and heat generation inside the unit. ASUS pairs this with GPU-First voltage sensing and a patented intelligent stabiliser, which prioritises stable delivery to the graphics card, the component most prone to sudden heavy draw. Full ATX 3.1 compliance and a native 12V-2x6 connector mean the 1200W rating is backed by the transient handling modern GPUs require.

ROG Equalizer Cable

In demanding 600W scenarios, uneven current distribution across the individual conductors of a 12V-2x6 cable can create localised hot spots at the connector, which has been a well-publicised failure point on high-end cards. The ROG Equalizer is a patented soft-embossed 12V-2x6 PCIe cable engineered specifically to reduce that heat stress and keep cable and connector temperatures in check. Including it in the box means the protection is there from the moment the build is finished.

Magnetic OLED Display and Turbo Mode

The OLED panel shows real-time power draw at a glance, and its magnetic attachment lets you move it to whichever side faces outward in your case, accommodating both fan-up and fan-down orientations. Turbo Mode combines premium components with a fine-tuned fan curve to support extended power excursions during overclocking or sustained heavy workloads. Lambda A++ certification confirms noise levels below 15dB in normal operation.

Cooling and Build

ROG heatsinks work alongside a fully aluminium enclosure to move heat away from the internal components and keep system thermals under control. The fan uses a dual ball bearing design, which can last around twice as long as the sleeve bearings fitted to cheaper units and is the usual reason a PSU becomes noisy with age. Etched modular cables in a pliable premium material make routing considerably easier during installation.
