Full in-depth review of a power supply is not really an elementary task, it demands the reviewer to be all set with the expensive and elite equipment in his inventory, which is remarkably costly, so, in our review, we will only be looking at the voltage stability of the PSU which can easily be done by a multimeter. The multi-meter we used in our test was UNI-T UT203. These readings are for 3.3v, 5v, and 12v lines. Minimum and maximum readings were noted.
Our CPU Intel 9th gen 9900K was overclocked to a safe 5.0GHz to put supreme load. We examined our system using Aida64 Extreme stress test with all options checked. CPU only was utilizing the total of 250W. Every computer component was on 100% load. So the values are assumed to change in different settings.
Principally this PSU can deliver the limitations imposed by voltage distributions idle, as it is equipped with a single +12V rail keeping up with the continuous stipulation of power to your system components according to their requirements. Its efficiency is the next extraordinary perk it brings with itself, embodying 80 Plus Titanium rating efficiency. Thermaltake Toughpower iRGB Plus 1250w is designed to work efficiently with almost any kind of load you’ll throw at it. The PSU can successfully run multi-GPU PC setups or dual CPU workstations as well with ease.
Last but definitely not the least, it provides a constant power of 1250w all the time at around 35-45c average of temperatures which is one of the most important aspects for your consideration.

So without wasting any time, let’s plunge directly into the performance benchmarks!
We took reading from both Thermaltake DPS and Multimeter, To be honest, we did not find a difference of bit in both results. In future we plan to test all the devices using proper tools and equipment the values from our multimeter, We do not see any difference of whatsoever in both 12V and 5V Rails between idle and load. However, 12V Rail is showing the result of 11.9-12V all the time we tested. As for the 5V Rail, it showed the difference of 0.06-0.07V by max. 3.3V Rail showed slight difference while in load and outcome was the difference of 0.01V. So the numbers here are very encouraging.
Power Supplies have a sensitivity rating and anything under 5% on the three rails mentioned above are admissible. And it’s immeasurable to see that we haven’t even bisected half the limit here. So performance-wise, this makes sure Thermaltake Toughpower iRGB Plus 1250w is an outclass PSU.
Overall, I’ll reiterate that the Thermaltake Toughpower iRGB Plus 1250w is definitely something which a class apart. Staying away from the tolerance limits while keeping the efficiency of the 80% PLUS Titanium as well.
