ASUS unveils its MONSTER 3000W ROG THOR Titanium III Edition 20 PSU

This PSU can power four RTX 5090 GPUs and has power to spare

At Computex 2026, ASUS is celebrating the 20th anniversary of ROG with new “Edition 20” series products. We’ve already looked at their ROG Edition 20 RTX 5090 and ROG Xbox Ally X20, and now we are looking at their ROG THOR 3000W Titanium III Edition 20 PSU.

With 3000W of power, this PSU can power four RTX 5090 graphics cards simultaneously. This PSU also ships with ASUS’ patented ROG Equalizer 12V-2×6 cable. Additionally, ASUS claims that its “GPU-First Intelligent Voltage Stabilizer” can deliver up to 45% improved voltage stability during peak gaming and extreme overclocking workloads. Nice additions for users of high-wattage graphics cards.

With this PSU comes a magnetic OLED display and a USB extender. This allows users to attach the OLED screen to their PSU, or mount it elsewhere inside their system. This is a great addition, as most modern PC cases have PSU shrouds, which make PSU-mounted screens invisible to users.

Note that this PSU only supports 3000W in 230V regions. This PSU has a “dual-voltage adaptive design” and supports up to 1600W in 115V regions.

The ROG Thor 3000W Titanium III Edition 20 has received an Award in the Computer & System category of the Computex Best Choice Awards 2026. We expect this PSU to be available soon alongside ASUS’ other Edition 20 products.
