Thermaltake was showcasing its upcoming Toughpower XT series of power supplies at CES 2009, along with its new 750-watt EVO_Blue power supply.

The new Toughpower XT series will be offered in 650-watt, 750-watt, 850-watt, 1000-watt and 1200-watt variants, with additional variations offering cable management abilities.  The Toughpower XT series features S.F.C quiet technology, a FanDelayCool function and three indicator lights, which indicate standby, PG signal and temperature status of the power supply.  

The FanDelayCool feature is a cooling function that can be enabled to allow the cooling fans in the PSU to continue to run after the system has been shutdown, at an interval of 15 or 30 seconds.  It would seem that this feature will help to increase the lifespan of the power supply.  The S.F.C quiet technology controls the fan so that it always spins at the optimal speed, reducing any unneccessary noise.

As for the indicator lights, Thermaltake wanted to give the user some feedback from the power supply to help them troubleshoot problems if they arise.  The PG signal light stands for "Power Good", which presumably means that the power supply is running well.  The temperature indicator light alerts the user to the power supply becoming too hot. 

The 1000-watt and 1200-watt variations meet the 80 PLUS Silver efficiency requirements, while the other variations in the series only meet the 80 PLUS Bronze efficiency requirement.  The new Toughpower XT series will cost about $50 more than the older Toughpower series.

Regarding the upcoming EVO_Blue power supply, it will be offered in at least a 750-watt version and seems to be designed for gamers.  The EVO_Blue features a silent 14-cm ball-bearing cooling fan with adjustable LED lighting that can be set to a variety of colors with a press of a button.  The power supply also has a modular socket with blue LED lighting, a single +12 V output, an active PFC and a universal AC input.  The price we heard get quoted was $159 and up.
