Thermaltake Toughpower XT 875W and Toughpower 1200W
Dec 31st, 2010 | By AnthonyThe aim of the cold test is to reflect ideal operational conditions where heat from the computer system is independent from the power supply. Still though, the term cold test would be misleading as things do get quite hot!
We’ll start with the Toughpower XT 875W.
Our first three tests went by quite well. In terms of line regulation each of the rails was solid, especially the 12V rail. Efficiency through the three tests hovered for the most part in the mid 87% range and by the third just under 87%.
After leaving the unit to cook for a bit inside the hot box, the rails still held quite well and all still within a percentage point. Efficiency however, as expected, did drop a bit down to 85.8%. Not too shabby at all.
Switching things up, let’s see how the Toughpower 1200W performs.
Starting with our usual 50%, 80% and 100% tests, we’re clearly looking at two different units- if our quick look at the insides wasn’t convincing enough. With the Toughpower 1200W, efficiency at 50% load was about 85% while by the full load tests, down to 83%. For a 1200W unit, that’s hardly a terrible thing, but we’ve definitely seen better before. But then, the Toughpower 1200W doesn’t claim to be 80Plus Gold rated.
In the hot box, we lost a few more points in efficiency, down to just under 83%. The lines however, held fairly well. Both the 12V and 5V rails in particular were rock solid in the 11.9V range and 4.9V range respectively. The 3.3V rail moved around a bit more than we’d like to see, but definitely, still, well within specifications at 3.23V.
