Load 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 DPS G 1050W 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 12V rail, we see 1% regulation from start to finish, with a total drop of .06V. The 5V rail managed to stay within 1% of specification, with a total drop of .05V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 1% of specification, with a total voltage drop of .05V.
DC Output quality for the Thermaltake Toughpower DPS G 1050W was excellent, and well within specifications. During Test One, we saw 12mV of noise on our scope at 21% load. When we increased the loads in Test Three, the ripple climbed to a 19mV at around 50% load. Increasing loads even further showed that the noise on the 12V rail climbed to 30mV at during Test Six at 1000W.
The Thermaltake Toughpower DPS G 1050W is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87% / 90% / 87% efficiency, at 20% / 50% / 100% loads respectively. As you can see, the Toughpower DPS G 1050W performs exactly as expected. Thermaltake has certainly achieved that happy medium where they are no longer skirting just the 80 PLUS Gold minimum, but aren't quite at the Platinum level.
This is the fifth or so digital unit that we have taken a look at thus far and the second unit that we've seen from Thermaltake. Being that we are still in the infancy stages of digital power supplies, I think it is safe to say that everyone wins with these units. Every digitally controlled unit that we have had thus far has performed on what was previously thought as a near flawless level of operation.
The Toughpower DPS G 1050W is no exception to this, doing what few have ever achieved and that is maintaining voltage regulation across the board within 1% of ATX specifications. Thermaltake does this while also maintaining excellent noise suppression and decent efficiency. The efficiency is also rather high on this unit as it stays solidly between the lines of 80 PLUS Gold and Platinum.
While we may not be able to say that the performance from the DPS G 1050W is unparalleled or that it is what the industry standard should be, we can say that the Thermaltake DPS G 1050W is probably the best unit on the market in terms of performance and value. The Thermaltake DPS G 1050W combines the best of both world's and this is truly what is the crème de la crème for consumers; excellent performance with exceptional value.
