The Toughpower PF1 ARGB with a capacity of 1200 W is a high-performance power supply with performance that successfully competes with the ASUS ROG Thor 1200 W based on Seasonic's Prime platform. OEM Channel Well Technology (CWT) did a good job of providing Thermaltake with a capable semi-digital platform. Thermaltake added the RGB lighting to make this product more desirable among users with windowed cases. I am not that fond of RGB lighting outside of Christmas, but apparently, demand for RGB exists or brands would not release such products.

The TPD-1200F3FAPU-1 offers a massive amount of connectivity on long cables with gauges thick enough to deliver the full load without significant voltage drops and energy losses. Moreover, I very much like the fact that the distance between peripheral connectors is large enough to avoid compatibility problems. Performance-wise, the PSU scores high in almost all areas, including transient response, which is among the most important. No power supply will operate with static loads under real-life conditions, which makes transient tests essential, and you should pay great attention to those results, especially for the +12V rail.

The major downside of this Toughpower unit next to its intimidating price tag is output noise. You should not expect a 1200 W PSU to be whisper quiet when fully loaded, but its fan profile could deal with light and medium loads considerably better. Overall efficiency should be a little higher as well, and the same goes for the 5VSB rail which scores low in this area. CWT has some highly efficient 5VSB regulators, which has me wonder why it didn't use one with this high-end platform. Finally, such an inaccurate power ok signal is plain weird for a PSU with such a high price tag. Given the hold-up time exceeds 17 ms, I do not understand why CWT didn't tune it properly as it lets the mainboard and rest of the system know whether it is safe to keep on operating. Thankfully, the hold-up time of the power ok signal is only 0.6 ms longer than the actual hold-up time, so voltage levels are not far from the lowest the ATX spec requires. If one of the two MCUs supports handling the protection features, it won't be hard to fix this issue in a future revision.

In general, the 1200 W Toughpower PF1 ARGB is a good PSU with the potential to become even better with a proper fan profile and less overall noise output.
