Compaq Evo D500 - Power Supply Assembly

Chapter 7 Power and Signal Distribution
7.1.1 POWER SUPPLY ASSEMBLY
The power supply assembly is contained in a single unit that features a selectable input voltage:
90-132 VAC and 180-264 VAC. Small Form Factor systems use a 120-watt supply while all other
systems employ a 200-watt supply. Tables 7-1 and 7-2 list the specifications of the power
supplies.
