Asus ROG Thor 1200W PSU Review – a heavily modified Seasonic!

Performance Rating

The following graph shows the RTSS01-1200P1’s total performance rating, comparing it to other units we have tested. To be more specific, the tested unit is shown as 100 percent, and every other unit’s performance is shown relative to it.


The performance is very high, however the SSR-1200PD scores higher. Surely the extra in-cable caps of the latter provide it with an edge. Since it lacks the OLED screen and the rest extra parts, the SSR-1200PD also has higher efficiency, which plays a major role in the final rating.

Performance Per Dollar

The following chart may be the most interesting to many of you because it depicts the product’s performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. Note that all of the numbers in the following graphs are normalized by the rated power of each unit.

The extra features like the OLED screen and the RGB lighting inevitably increase the product’s price, so even at 250 bucks which is a reasonable price, it doesn’t stand so well against the competing offerings. The recent huge price drops in high capacity units will probably create problems to this model’s sales career.

Noise Rating

The graph below depicts the cooling fan’s average noise over the PSU’s operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).

This is the quietest 1200W PSU that money can buy today! Even the super quiet HX1200i cannot compete with it.

Efficiency Rating

The following graph shows the PSU’s average efficiency throughout its operating range, with an ambient temperature close to 30°C.

Asus’ offering scores a bit lower than the original Seasonic platform here, because it uses a number of additional parts which require extra power of course.
