Dell Dimension 2100 DC Power Cables DC Power Connector Pin Assignments, DC Voltage Ranges

The 145-watt (W) power supply can operate from an AC power source of 115 volts AC (VAC) at 60 hertz (Hz) or 230 VAC at 50 Hz. The power supply provides the DC operating voltages and currents listed in the following table.

NOTE: The power supply produces DC voltages only under its loaded condition. The DC power cable connectors must be connected to their corresponding power input connectors on the system board or drives to measure these voltages.

DC Voltage Ranges

		Maximum Output
Voltage	Range	Current
+3.3	+3.14 to +3.47 VDC	10.00 A
VDC
+5 VDC	+4.90 to +5.25 VDC	16.00 A
–5 VDC	–4.50 to –5.50 VDC	0.300 A
+12 VDC	+11.40 to +12.60	4.5 A
	VDC
–12 VDC	–10.80 to –13.20	0.300 A
	VDC
+5 VSB	+4.75 to +5.25 VDC	1.2 A

Notes

The combined load on the +3.3-VDC and +5-VDC outputs cannot exceed 85 W.

The combined load on the +3.3-VDC and +5-VDC outputs cannot exceed 85 W.

The +12-VDC output can withstand surges of up to 11.0 A to support disk start-up operations.

The +5 volts standby (VSB) is sometimes called volts flea power (VFP).

DC Power Connector Pin Assignments

The power-supply output voltages can be measured at the back (wire side) of the DC power connectors without disconnecting them. The following figures show the wire side of the connectors:
