Thermaltake was established in 1999, Headquartered in Taipei, Taiwan. Best recognized for their coolers, power supplies, chassis, and gaming merchandise. We have in the past reviewed a few products from Thermaltake including the View 22 TG, Smart RGB 700W 80+, Thermaltake Versa N26 and have always found them to be wonderful. This season around though, we’re looking at something especially intense and expensive from Thermaltake.

The Thermaltake Toughpower iRGB Plus series comes in four variants which are: 850W
1050W, 1200W, and 1250W (Each with different power-efficiency rating). The variant we’re going to review is the Thermaltake Toughpower iRGB Plus 1250w behemoth of a power supply. Not only that, it is a Titanium rated which means after purchasing it you’ll enter the elite-realm of PC Master Race. The most highlighting innovation of this PSU includes a well-engineered highly effective power management feature which can be controlled via software and if that wasn’t satisfying, RGB lighting. RGB lighting is unquestionably something Thermaltake takes seriously which we also saw in the Smart RGB 700W.

Talking about the RGB Fan of the PSU, You can set almost any color combination for the fan via software there’s a nice glow to it which gives a nice look to your rig if the PSU fan is facing upwards.


The software “DPS G App” of the Thermaltake Toughpower iRGB Plus 1250w is the most highlighting feature of the PSU. DPS G application is very detailed, customizable and handy. It might look like a little complex at first but when you’ll get the hang of it, things will be easier for you then.


The main tab of the software contains all sorts of information regarding the PSU, Thermaltake didn’t skip any of their hardware. They’ve installed sensor literally for everything from the Fan speed, PSU Efficiency to all 12V, 5V and 3.3 rails.

The most amazing feature of the software is the Output wattage monitor. Gone are the days in which you had to install a custom output wattage meter in order to read the calculations of the PSU. In the Thermaltake Toughpower iRGB Plus 1250w, Thermaltake has integrated a built-in output wattage meter ran and controlled by the DPS G App. You’ll have full real-time monitoring of how much juice your PSU is outputting currently which is really impressive.

Total Electric Bill cost, Average efficiency, Total KWH, and a graph of the PSU consumption are also present in the software. All of these features can come in handy for a lot of tech-enthusiasts who love to test the power consumptions of different components of their PC.

The second tab on the DPS G application lets us control RGB fan lighting mode. We have the different range of options i.e. Flow, RGB Spectrum, Ripple, Blink, Pulse, Wave, Full Lighted & Thermal Mode. The most amazing part of this software is that it lets the user control all the individually addressable RGB LEDs in that fan. Which is pretty amazing.

The software also shows some of the info of other PC components as well. CPU temp, CPU power consumption and ram usage along with storage information as well.

Overall the software is a full-package contained with all sorts of digital monitoring values which is really impressive and unique at the same time. We are more than satisfied with the software of the Thermaltake Toughpower iRGB Plus 1250w.

Mobile Application

I have tried to get Thermaltake DPS mobile application working but it was not recording data from power supply due to some reason. I could, however, test RGB & Remote features. I think probably the mobile app is outdated so I would love to hear from Thermaltake on this.


Testing Methodology:
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!

thermaltake iRGB 1250W result

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.


The Thermaltake Toughpower iRGB Plus 1250W is an exemplary power supply that provides us a bit of a fit today. During testing, we saw test results from the Toughpower iRGB Plus 1250W that showed us exceptional voltage regulation, great Transient Load Test results, and top DC Output Quality. Additionally, the unit is extremely robust and has several extra features including the flawless software that gives you a wide range of monitoring aspects of the PSU that a lot of users will appreciate along with a long 10-year warranty.

However, the only thing might hold this Thermaltake Toughpower iRGB Plus 1250W behind is its price range, because of the price tag a lot of entry-level users might ignore this PSU because they just can’t afford a 400$ PSU, but this PSU wasn’t built for the entry-level user either. So this isn’t a big deal, but still, the price could get better. When you take a glance at the pricing of the units that come with individually sleeved cables, then the pricing begins to make much better sense, as you can pay $100 very quickly on these types of cables for adding a custom look to your build. If you perceive value in these incorporated cables the price makes very genuine sense, however, if you see no value in the aesthetics of it all, you can preserve more than a few dollars with another unit that is just as great. In a nutshell, Thermaltake has produced an outstanding power supply that is award-worthy on performance alone.
