The GT062E uses an industry-standard power cord and a pro-quality internal power supply for the most efficient, reliable power source possible. GT062E will also sense when you connect over USB or FireWire, and automatically power on. The GT062E uses a temperature-controlled fan making it overall quieter than previous designs while still offering proper cooling. The case is designed with front-panel ventilation holes to draw cool air in, while exhausting warm air out the back - critical to the performance and reliability of the components.
