Test Results


Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.


The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are lower than that of the Thermaltake Toughpower XT Platinum 1275W power supply, we can only test it to 1000W.




The above tests represent typical loads that we have measured from various systems and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different and actual loads can vary greatly even with similar hardware.




Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V1 rail, we see 2% regulation from start to finish with a total drop of .16V. 12V2 showed nearly identical results with 2% regulation and a total drop of .20V. The 5V rail managed to stay within 2% of specification as well with a total drop of .05V from start to finish. Moving towards the 3.3V rail, we see that regulation was again within 2% of specification with a total voltage drop of .05V.


DC Output quality for the Toughpower XT Platinum 1275W was great and well within specification. During Test 1, we saw 19mV of noise on our scope. When we increased the loads in Test 3, the ripple climbed to 28mV at a little under half load. During Test 6 under a load of 1000W, the oscilloscope showed a maximum of 44mv on noise on the 12Vrail.


The Thermaltake Toughpower XT Platinum 1275W is rated for 80 PLUS Platinum efficiency. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. As you can see, the Toughpower XT Platinum 1275W passed on our bench and wasn't close to failing at any point.



Final Thoughts


Thermaltake's Toughpower XT Platinum 1275W is the third power supply we have taken a look at to date that is rated for both 80 PLUS Platinum efficiency and more than 1000W. The other two have been the Corsair AX1200i and the PC Power & Cooling Silencer Mk III 1200W. Performance for the Toughpower XT Platinum 1275W is just what you would expect from this enthusiast grade power supply.


All voltages are within 2%, it has great DC output quality, and Platinum level efficiency just as advertised. This makes it very hard to distinguish the power supply from the competition as all of these power supplies have performed extremely well and with very minimal differences in the test results.


When you start looking at some of the features and specification, we find the ability to start to differentiate the three. We find that the Corsair AX1200i is by far the most feature-rich with the integration into the Corsair Link software and the PC Power & Cooling Silencer Mk III 1200W brings a massive single 12V rail while the Thermaltake has dual 12V rails. All three units feature seven year warranties as well.


Once we take price into consideration, we find a huge difference between the three and this is most certainly where the Thermaltake Toughpower XT 1275W power supply shines. At a price of about $270 after shipping, that makes it at least $30 less than the competition, and $80 less when compared to the Corsair PSU. That's a good chunk of change that can be dumped elsewhere into a system to gain more performance.


So, unless you demand the monitoring features of the Corsair or the single 12V rail of the PC Power & Cooling, the Thermaltake currently represents the best value for an 80 PLUS Platinum power supply that is capable of more than 1000W.
