Power Supply Units (PSUs) are a critical component of any computer system, converting Alternating Current (AC) power from a wall outlet into Direct Current (DC) power that the system's components can use. The PSU connects to the motherboard via a specific connector, and the configuration of this connector, or pinout, varies by PSU model and manufacturer. The Dell D220p 01, like other PSUs, has a specific pinout that dictates how power is distributed to various components.

The (DA-2 Series) power supply uses a proprietary 8-pin connector to deliver 12V DC at 18A (220W/216W). 8-Pin Connector Pinout Dell D220p 01 Power Supply Pinout 2
Below is the , 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.
Before altering the wiring, confirm your hardware aligns with these baseline specifications of the DA-2 brick: D220P-01 / ADP-220AB B Dell Part Numbers (DP/N): M8811, N112H, Y2515, D3860, MK394 Input Voltage: 100–240V AC ~ 4A (50–60 Hz) Output Voltage: 12V DC Current Rating: 18A Continuous
Some D220P-01 units omit pins 4 and 6, leaving a 4-pin connector (positions 1,2,3,5 only). In that case: Pin1=Purple, Pin2=Black, Pin3=Green, Pin5=Gray. : You must interface with the Blue wire
