Thermaltake has announced that it is adding several power supplies to both the Toughpower and SMART PSU lines. The Toughpower line will be adding supplies with output capacity of 550W, 650W, and 750W. All three of these PSUs are 80Plus Gold certified. Active CLAMP circuitry will provide for high efficiency and low power loss, and also features protection against short-circuits, over voltage, and under voltage, among other unwanted circumstances. The SMART series will receive 750W and 850W units, both of which will feature modular cables allowing you to use only what you need. The two SMART series PSUs are 80Plus Bronze certified, and will be kept cool with the presence of a 140mm cooling fan.
