OK, so we've seen the graphs over on the previous page. Now here's the data that they were derived from.

Once again it's hard to really find any fault with the ToughPower XT's results. It puts out good efficiency levels, the exhaust temperatures are about average, the voltages at 100% load are highly respectable and the unit was completely unfazed by the cross-load tests. Furthermore, being able to run at 990w continuous is pretty damn impressive for a PSU rated at 775w and although the voltages were on a downward turn at this point, it felt like the unit could easily break 1KW if pushed a little further.
|Thermaltake XT 775w Scope Results @ 50c |
ATX specification states that ripple should be no higher than 50mV on the +3.3v/+5v rails and 120mV on the +12v rails, and judging by those flat lines in the screenshots above the ToughPower XT 775w certainly had no trouble meeting these requirements in all of the tests. In fact, with the highest results recorded being 24mV on the +5v rail and 54mV on the +12v rail, the XT actually keeps the ripple at below half of what is required. Awesome.
Now that we've got a good idea of how it looks and how it performs, lets move on to the conclusion page and try to bring it all together...
