This guide is intended for electronics hobbyists, repair technicians, and PC builders who wish to repurpose this specific power supply or troubleshoot it outside of a Dell OptiPlex chassis.
| Pin | Signal | Wire Color | Function | |-----|------------|--------------|--------------------------------------------------------------------------| | 1 | +5VSB | Purple | (always present when AC plugged in). 2A max. | | 2 | GND | Black | Return path for +5VSB and PS_ON#. | | 3 | PS_ON# | Green | Power Supply On (active low). Short to GND to turn on main outputs. | | 4 | GND | Black | Additional ground. | | 5 | PW-OK | Gray | Power Good (goes high ~5V when all rails are stable, 100-500ms after startup) | | 6 | NC / N/C | (Empty) | Not connected on D220P-01. Sometimes used for fan tachometer on other Dell PSUs. |
If you are searching for , you are likely staring at the smaller 6-pin or 4-pin secondary connector and wondering:
| Pin # | Description | Pin # | Description | |-------|--------------|----------------|-----------------| | 1 | 3.3V | 11 | 3.3V | | 2 | 3.3V | 12 | -12V | | 3 | GND | 13 | GND | | 4 | 5V | 14 | PS-ON | | 5 | GND | 15 | GND | | 6 | 5V | 16 | 5V Standby | | 7 | GND | 17 | 5V | | 8 | 12V | 18 | 12V | | 9 | 12V | 19 | 5V | | 10 | 5V | 20 | 3.3V or PWR_OK |
These are the GND (Ground) pins, completing the circuit for the 12V rails.
