ASUS ROG Thor 1200W Platinum III ATX v3.1 PSU Review

The ASUS ROG Thor 1200W Platinum III is a high-end PSU using a Seasonic platform. It features GaN MODFETs so it will be interesting to see how it performs. There is also a magnetic-mount OLED display showing real-time power draw. The cool fact with this display is that it can be swapped to either side of the PSU. 

The ASUS ROG Thor 1200W Platinum III is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.

The ASUS ROG Thor 1200W Platinum III is an expensive, high-end ATX v3.1 compliant PSU using a Seasonic platform with MODFETs on its APFC converter. This PSU also has an OLED display that can be mounted on either side, showing real-time power draw from the wall. The rest of the features of this PSU include etched modular cables, large heatsinks at its internals to minimize the fan’s workload and noise, a turbo mode switch at its front side for spinning the fan at high speeds and a voltage sensing system for its 12V-2×6 connector which promises a tighter load regulation under high transient loads.

  1. Aris i’ve seen that Cougar GLE1000/1200 cybenetics the data OEM said it was CE-Link, but i was bought the GLE 1000 and they said on a label it was Compucase or HEC, which it’s true about this CE-Link or HEC/Compucase ?

    1. As I remember I asked Cougar about the OEM and they told me CE-Link, because at some point it is difficult to recognize who actually made the PSU.
