Closer Look

Taking a gander at the power supply itself, we find some new features staring back at us. First, right next to the traditional rocker switch on the back of the PSU beside the power port is a three-position switch called the Fan Delay Cool. This switch allows you to choose an independent shut-off time for the Toughpower's 140mm internal cooling fan. Adapted from the cooling on high-end projectors, this feature has an auto, 15 second, or 30 second setting to allow the internal components ample time to cool down after operation. By inhibiting the heat-up of the internal components that usually occurs when a PSU goes dark, the Fan Delay Cool feature will help to extend the life of the internal resistors. The longer your resistors last, the longer the PSU will be a dependable source of power for your PC.

Along with the Fan Delay Cool feature, Thermaltake has employed an integrated S.P.T. Indicator display into the casing itself. This is a series of three lights on the side of the power supply that show the standby, Power Good signal and temperature status of the Toughpower XT 750w. This real-time display gives first-hand warning of PSU health problems or over-stressing of the system.

All these features go to protect the guts of this PSU: the capacitors. Inside the Thermaltake are high-quality Japanese-made capacitors. Clean, dependable, long lasting power can only be had by high-end internal components, and the Toughpower XT is up to the task. Both the primary and secondary side of the PSU are made up of these capacitors, and voltage fluctuation should be at a minimum as a result. We will be putting that to the test.

One more thing we find that sets this power supply apart is the fact that the 12v rail is fully independent, offering the vital 12v current the most stable flow possible. This eliminates many common PSU problems due to inadequate amperage due to uneven distribution of current over multiple rails. In other words: a lot of thought has gone into the design of this power supply to deliver some real piece of mind and unwavering stability on paper. Let's see how it does when faced with some real-world testing.
