DC Voltage Ranges
The low-profile chassis has a 145-W system power supply, whereas the midsize and mini tower chassis have a 200-W system power supply. The system power
supplies can operate from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz. The system power supplies provide the DC operating voltages and
currents listed in the table below.
1 The combined load on the +5-VDC and +3.3-VDC outputs cannot exceed 105 W on the low-profile computer or 140 W on the midsize and mini tower
chassis.
2
Withstands surges of up to 11.0 A to support disk start-up operations.
3 VFP (volts flea power) — sometimes called "standby power."
DC Power Cables (Low-Profile Chassis)
NOTE: Each power supply produces DC voltages only under its loaded condition. Therefore, when you measure these voltages, the DC power
connectors must be connected to their corresponding power input connectors on the system board or drives.
