Most guides mention "Pinout 2" referring to the secondary 4-pin connector near the 20-pin. On standard ATX, this is a P4 12V CPU connector. On the D220P-01:
| Pin | Dell D220P-01 | Standard P4 | |-----|---------------|--------------| | 1 | GND | GND | | 2 | GND | GND | | 3 | +12V1 | +12V | | 4 | +12V2 | +12V | Dell D220p 01 Power Supply Pinout 2
However, the D220P-01 sometimes routes +3.3V or +5V instead of +12V on certain revisions (especially in small form factor models). Always verify with a multimeter. Most guides mention "Pinout 2" referring to the
"Pinout 2" warning: If your D220P-01 has a 2×2 square 4-pin connector with yellow/black wires only, it is standard +12V. If it has red/orange wires, it is NOT a CPU connector – it may be for powering an IDE drive or proprietary Dell riser card. "Pinout 2" warning: If your D220P-01 has a
| Pin | Wire Color | Signal | ATX Equivalent? | |-----|------------|--------|------------------| | 1 | Grey | +5V SB | Yes (same) | | 2 | Black | GND | Yes | | 3 | Black | GND | Yes | | 4 | Orange | +3.3V | Yes | | 5 | Red | +5V | Yes | | 6 | Red | +5V | Yes | | 7 | Blue | -12V | Yes | | 8 | Yellow | +12V1 | Yes | | 9 | Yellow | +12V1 | Yes | | 10 | Brown | +12V2 | No – Secondary 12V | | 11 | Black | GND | Yes | | 12 | Orange | +3.3V | Yes | | 13 | Orange | +3.3V | Yes | | 14 | White | -5V | Obsolete – rarely used now | | 15 | Black | GND | Yes | | 16 | Green | PS_ON | Yes (active low) | | 17 | Black | GND | Yes | | 18 | Grey | PWR_OK | Yes | | 19 | Red | +5V | Yes | | 20 | Purple | +5V SB | Yes |
Critical difference: Pin 10 is Brown (+12V2), not the typical -5V or empty.
Missing: No +12V on Pin 10 in ATX; do not plug into a standard motherboard without an adapter.
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.
