ASUS ROG Thor 1200w Platinum Power Supply Review

Efficiency, PFC and Voltage Regulation

Voltage Regulation

With the ASUS ROG Thor being a high-performance power supply, we expect some decent results from it. No less because of the platinum efficiency rating (which we’ll get onto shortly). In terms of the voltage regulation though, things get off to a great start. While there is a little variance in the overall percentages, the results across the differing rails are remarkably consistent.

Every single rail test provides solid scores regardless of the load with a particular highlight being the 3.3V. Notice how it is entirely 3.3v throughout the testing? – Truly remarkable!

Power Efficiency

With this power supply being platinum rated, it is required to meet exceptionally high-standards in terms of how efficiently it converts that raw power where it’s required. While the initial 20% scoring is a little lower than we would like to have seen, it is close enough to 90% for us to call this within a reasonable margin of error.

Overall, the ASUS ROG Thor meets the platinum standards, but not by any notable margin. This is platinum, but unlike power supplies that are usually a little reserved in their ratings (which prove to be better in testing), this is exactly what it should be. That’s not, incidentally, a criticism. It’s just a fact.

Power Factor Correction

While the initial power rating for the ASUS ROG Thor is a little lower than we would have expected, when the power starts getting cranked out, the figures get much, much, better. Achieving a PFC of around 0.98 at 100% is certainly very impressive. It does, however, indicate that based on this and the efficiency ratings, this power supply is at its best when working hard!
