Dell Dimension 4300 DC Power Connectors, Pin Number Signal name 18-AWG Wire

+5 VDC	+/–5%	1.0	22.0
+3.3 VDC	+/–5%	0.1/0.04	18.0
–12 VDC	+/–10%	0.0	1.0
+5 VFP	+/–5%	0.0	2.0

When the current load is outside of the ranges listed, but within each specified output current range, the +5-V, +12-V, and +3.3-V outputs are allowed to regulate at +/–10% of nominal DC voltages.

1In system applications where +3.3 VDC is not used, these values may be 0 A without affecting the regulation on the other outputs.

2Peak +12-VDC output power (up to 12 A) does not exceed 15 seconds in duration. In this condition, the tolerance on the +12-V output is allowed to be +/–10%.

3The required full load combinations are adjusted so that the total output power is less than or equal to 250 W.

4Maximum continuous total DC output cannot exceed 200 W. Maximum continuous combined load on +5-VDC and +3.3-VDC outputs cannot exceed 135 W.
