Dell D220p 01 Power Supply Pinout 2

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.

Step-by-Step:

Disconnect the PSU from AC power.
Identify the secondary connector (smaller of the two).
Locate the Green wire (Pin 3) and any Black wire (Pin 2 or 4).
Insert a jumper wire (paper clip or wire with dupont connector) between Green and Black.
Apply AC power. The PSU should start immediately (fan spins, main outputs active).

Warning: The D220P-01 does not require a load on +5V or +12V to start, unlike some older ATX supplies. However, for stable voltage regulation, a minimum load of 1-2A on +5V is recommended (use a 2.5Ω, 10W resistor or an automotive bulb on the red/black wires of the main connector).

1. ATX (Main Power) Connector

The ATX connector is usually a 20-pin or 24-pin connector that supplies power to the motherboard. Dell D220p 01 Power Supply Pinout 2

For a 20-pin ATX connector, pins 21-24 are usually reserved or used for different functions. This guide is intended for electronics hobbyists, repair

The Auxiliary 4-Pin "P4" Connector

Most D220P-01 units include a small 4-pin square connector (often labeled "P4") for the CPU VRM. This matches the standard ATX12V connector electrically, but check the colors.

Pin 1 & 2: Black (Ground)
Pin 3 & 4: Yellow/White (+12VA)

Wiring caution: This 4-pin connector is keyed identically to standard P4 connectors. It is safe to use on any standard motherboard that requires a 4-pin CPU power. Step-by-Step:

The PSU has multiple connectors for powering different components of a computer system, including the motherboard, hard drives, and graphics cards.

Safety and Compatibility Considerations

Voltage Compatibility: Ensure that the voltage supplied by the PSU matches the requirements of the connected devices.
Grounding: Proper grounding is crucial to prevent electrical shocks or damage to components.
Wattage: Make sure the PSU can supply enough power for all components.

Common Adapters and Conversion Issues

Q: What does "Pinout 2" refer to specifically?

A: In Dell service manuals and forum discussions, "Pinout 1" usually refers to the main 20-pin power connector. "Pinout 2" unambiguously refers to the secondary 6-pin control connector covered in Section 2 of this article.
