| Pin | Signal | Wire Color | Typical Gauge | |-----|--------|------------|----------------| | 1 | +3.3V | Orange | 18 AWG | | 2 | +3.3V | Orange | 18 AWG | | 3 | GND | Black | 18 AWG | | 4 | +5V | Red | 18 AWG | | 5 | GND | Black | 18 AWG | | 6 | +5V | Red | 18 AWG | | 7 | GND | Black | 18 AWG | | 8 | PG (Power Good) | Gray | 22 AWG (signal) Note: On D220P-01, this pin is often unused or tied low; real PG is on secondary connector | | 9 | +5VSB (Standby) | Purple | 20 AWG Note: May not be present on main connector; check secondary | | 10 | +12V | Yellow | 18 AWG | | 11 | +12V | Yellow | 18 AWG | | 12 | +3.3V | Orange | 18 AWG | | 13 | GND | Black | 18 AWG | | 14 | PS_ON# | Green | 22 AWG (signal) If green wire is absent, PS_ON# is on secondary connector | | 15 | GND | Black | 18 AWG | | 16 | GND | Black | 18 AWG | | 17 | GND | Black | 18 AWG | | 18 | -12V | Blue | 22 AWG | | 19 | +5V | Red | 18 AWG | | 20 | +5V | Red | 18 AWG |

Look at the flat face of the connector with the locking ramp facing up. Pin numbering from left to right, top row then bottom row. Dell D220p 01 Power Supply Pinout 2

200W max. Do not exceed 12A on the 12V rail if other rails are heavily loaded. Section 5: Common Problems & Troubleshooting the "Pinout 2" Problem 1: PSU does not turn on when shorting Green to Black on the main 20-pin. Solution: The D220P-01 ignores the main connector’s PS_ON# (Pin 14 is empty). You must use the Green wire on the secondary 6-pin connector. Problem 2: Fan spins for 1 second then stops. No output. Solution: This is often a sign of overcurrent protection or missing +5VSB load. Ensure your jumper is secure. Also check if any output rail is shorted. The D220P-01 uses "latching" overvoltage/overcurrent protection – you must unplug AC for 30 seconds to reset. Problem 3: Measuring +5VSB on purple wire but PW-OK stays low (0V) when PSU is on. Solution: PW-OK only goes high after the main rails (+3.3, +5, +12) stabilize (100–500ms). If PW-OK remains low, the PSU has a fault (bad capacitor or overload). Recap: The D220P-01 is notorious for bulging 1000µF, 16V capacitors on the secondary side after 10+ years. Problem 4: Finding the correct pin numbering on the 6-pin connector. Solution: Hold the connector so the wire exit is facing you and the locking ramp is on top. The pins are arranged as: | Pin | Signal | Wire Color |

Article last verified with actual D220P-01 hardware and Agilent multimeter. Wire colors and pin functions confirmed as of 2025. Do not exceed 12A on the 12V rail

The control connector wiring varies – but the principles above (identify Purple, Green, Gray) apply across most Dell proprietary units from 2002–2008.
