Toughpower XT is an updated version of the famous Toughpower series from Thermaltake, featuring two novelties. First, a set of three LEDs that gives you basic status about the power supply working conditions. Second, a switch where you can configure the power supply fan to keep spinning for 15 or 30 seconds after you turn off your PC, which in theory can increase the product life-span. Another difference is the use of a single-rail design, while the original Thoughpower series uses a four-rail design. Let's test the 750 W model and see if it is a good buy.
