ThermalTake is working on Toughpower Grand power supplies with 80Plus Gold certification, which means they have a minimum efficiency of at least 88 percent, and minimum 92 percent efficiency at 50 percent load. These units feature a single +12V rail and will be available in 650W and 750W variants.
The Toughpower Grand series has semi-modular cabling, a 140mm fan and a design with rounded corners. ThermalTake claims these rounded corners will find their way onto more power supplies in the future. These new PSUs are expected to be available in April.
