The OptiPlex G1 systems are equipped with a switch-selectable (115-/230-VAC)
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 model than that used in the
low-profile chassis configuration.
Dell OptiPlex G1 systems have a special power supply that provides trickle
(“flea”) power to support the Wakeup On LAN feature when computer power
is off.
