The OptiPlex NX1 computers have an 80-W computer power supply. The power supply can operate from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz. The system power supply provides the DC operating voltages and currents listed in Table 1-5. NOTE: The power supply produces DC voltages only under its loaded condition. Therefore, when you measure these voltages, the DC power input connectors must be connected to their corresponding power input connectors on the system board and hard-disk drive. System Overview 1-31
