The OptiPlex GX1/GX1p and OptiPlex NX1 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
power supply than that used in the low-profile and OptiPlex NX1 chassis
configurations.

Dell OptiPlex GX1/GX1p and OptiPlex NX1 systems have a special power sup-
ply that provides trickle (“flea”) power to support the Wakeup On LAN feature
when computer power is off.

Figures 1-3 through 1-6 show internal features of the four chassis types.
