The ROG Thor 3000W Titanium III Edition 20 is easily one of the most overbuilt power supplies shown during the ROG press event at Computex 2026. This isn’t meant for typical builds, it’s clearly designed for extreme multi-GPU setups, with support for up to four NVIDIA GeForce RTX 5090 cards.

What stood out immediately is the use of GaN MOSFETs. Compared to traditional designs, this allows the PSU to stay relatively compact while handling massive power output, and it runs noticeably cooler under load. It’s still a huge unit, but not as impractical as you’d expect for something rated at 3000W.

ROG is also pushing its dual-voltage adaptive design here, meaning it can handle different power standards globally without needing manual switching. That’s useful for creators or professionals moving between regions, but realistically, this kind of PSU is going into a fixed high-end setup.

On the power delivery side, ASUS added what they call the ROG Equalizer and a GPU-First Intelligent Voltage Stabilizer. The goal is simple, cleaner and more stable power delivery, especially when multiple GPUs are under heavy load. Based on the demo, voltage stability looked consistent even during simulated peak loads, which is critical for extreme overclocking scenarios.

The OLED display is still here, but now it’s detachable and magnetic. You can mount it outside the case if needed, which actually makes more sense for monitoring in complex builds where the PSU isn’t visible.

It also picked up a Computex Best Choice Award for 2026, which isn’t surprising given how niche and over-engineered this unit is.

The Thor 3000W Titanium III Edition 20 isn’t trying to appeal to everyone and it shouldn’t. This is for a very specific audience running multi-GPU or workstation-level systems. For anything less, it’s complete overkill.
