Universal Power Supply
The OptiPlex GXa and OptiPlex NX systems are equipped with a switch-
selectable (115-/230-VAC) universal power supply that can operate from
standard AC power outlets in the U.S. and all international countries. The
power supply used in the midsize and mini tower chassis configurations is a
higher-capacity power supply than that used in the low-profile and NX chassis
configurations.
Dell OptiPlex GXa systems equipped with the EM system board and all
OptiPlex NX systems have a special power supply that provides trickle (“flea”)
power to support the Wakeup On LAN feature when computer power is off.
