Power Supply
The power supply provides up to 300 watts of power, and uses a manual switch for selecting
either 115 VAC (90-132 VAC range) or 230 VAC (180-264 VAC range) for domestic or
oversea locations. The input frequency is 47-63 Hz, single phase. Input current is 5 amps
maximum for the 115 VAC range and 2.5 amps for the 230 VAC range. At full load, the
power supply has a minimum efficiency of 65 percent. The power supply is enclosed in a
case that includes a fan to provide additional airflow through the system.
When you connect AC power to the system, the computer is powered in its lowest “trickle”
power state (the 5V Standby output is On) and the Power LED glows yellow, though the fans
do not run. In this respect, the TDZ 2000 GX1 is always powered on.
The power supply contains no user- or field-serviceable parts. You must install a new power
supply if an internal component is defective.
The power supply has the following DC output specifications.
