1200W Platinum PSU for high-end builds

The ASUS ROG Thor 1200W Platinum II is a fully modular ATX power supply rated at 1200 watts. It targets enthusiasts building high-performance desktops that demand stable, efficient power delivery. An integrated OLED panel shows real-time power draw so you can monitor system load at a glance.

Fully modular cables and Lambda A++ quiet operation

Because every cable is detachable, you connect only what the build needs, reducing clutter and improving airflow inside the case. A 135mm Axial-tech fan with PWM control works alongside ROG heatsinks on critical components to keep temperatures low. Lambda A++ certification confirms exceptionally quiet performance under load.

Replaces older or lower-efficiency units

This unit steps in when an existing supply cannot meet the wattage or efficiency demands of a modern high-end GPU and CPU combination. The 80 Plus Platinum rating and 100% Japanese capacitors deliver cleaner power with less waste heat. Buyers who need more than 1200 watts or who prefer a non-modular design should look elsewhere.
