Dell D220p 01 Power Supply Pinout 2 < SIMPLE × PLAYBOOK >

The pinout of the Dell D220p 01 PSU typically includes several key connectors:

The specific pinout for the Dell D220p 01 includes:

However, without the exact Dell D220p 01 documentation, these specifics can vary. It's essential to consult the manufacturer's documentation or a reliable source for the precise pinout.

| 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. Dell D220p 01 Power Supply Pinout 2


Before we list the pins, understanding why the pinout is unique is crucial. A standard ATX connector has distinct colors (Orange 3.3V, Red 5V, Yellow 12V, Black Ground, and a Green PS-ON). The Dell D220P-01 abandons the color code entirely.

Key Differences:

If you plug a standard ATX connector into a Dell motherboard that expects this pinout, you will likely short 12V to ground. Conversely, if you adapt this PSU for a standard PC, you must re-pin the connector.

The Dell D220P-01 is a 200-watt ATX-style power supply unit (PSU) that shipped predominantly with Dell Optiplex GX270, GX280, and Dimension 3000/4600 series desktops in the mid-2000s. While modest by today’s standards (12A on the 12V rail), this unit has found a second life among electronics hobbyists, retro PC builders, and bench-top power supply converters due to its compact size, reliable Delta Electronics construction, and—most importantly—its unique two-connector pinout.

If you are searching for "Dell D220p 01 power supply pinout 2", you are likely staring at the smaller 6-pin or 4-pin secondary connector and wondering:

This article provides the complete, verified pinout for both connectors, wiring color codes, voltage readings, and step-by-step instructions for converting this unit into a standalone 12V/5V/3.3V bench supply.


The Dell D220p 01 PSU is a 220-watt power supply designed for efficiency and reliability. It features an 80 PLUS certification, indicating that it meets certain standards for efficiency. The PSU has multiple connectors for powering different components of a computer system, including the motherboard, hard drives, and graphics cards.

Below is the verified Dell D220P-01 pinout, as seen from the back of the connector (wires entering). This is not standard ATX. Connecting this to a standard motherboard will destroy both units. The specific pinout for the Dell D220p 01 includes:

| Pin | Signal | Wire Color | Standard ATX Equivalent | Function | |-----|--------|------------|-------------------------|-----------| | 1 | +5V SB | Purple | +5VSB | Standby voltage (always on) | | 2 | GND | Black | GND | Ground | | 3 | +5V | Red | +5V | +5V DC | | 4 | +5V | Red | +5V | +5V DC | | 5 | GND | Black | GND | Ground | | 6 | +5V | Red | +5V | +5V DC | | 7 | GND | Black | GND | Ground | | 8 | PS_ON | Green | Gray (PW-OK) | Power On (active low)this is the critical difference | | 9 | -12V | Blue | -12V | -12V DC | | 10 | GND | Black | GND | Ground | | 11 | PW-OK | Gray | Green (PS_ON) | Power Good signal – swapped with pin 8 | | 12 | +3.3V | Orange | +3.3V | +3.3V DC | | 13 | +3.3V | Orange | +3.3V | +3.3V DC | | 14 | +3.3V | Orange | +3.3V | +3.3V DC | | 15 | GND | Black | GND | Ground | | 16 | GND | Black | GND | Ground | | 17 | GND | Black | GND | Ground | | 18 | +3.3V sense | Brown | N/C or -5V | Remote sense for 3.3V regulation | | 19 | +5V | Red | +5V | +5V DC | | 20 | +5V | Red | +5V | +5V DC |

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 |

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.

"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.
