Once upon a time, Thermaltake sent me a brand new unit called the Toughpower XT. This unit, although priced and targeted as being one of Thermaltake's best, ultimately came up short when it came to performance.

Thermaltake wasn't content to just let things be, however. They went back to the drawing board and now claim to have improved the performance of the Toughpower XT series. Today, I have one of these new units on hand, rated at 750 watts. We're going to find out how much improving they did.
