This is the control pin. To turn the power supply on, this pin must be shorted to Ground (GND).
Understanding the pinout of the unique 8-pin "Y" connector is essential for safely adapting this unit for custom projects. The Dell D220P-01 Connector Overview
⚠️ While Dell usually follows standard conventions (White or Red for +12V, Black for Ground, Blue or Green for Remote), wire colors can vary by manufacturing batch. Always verify your pinout with a multimeter before connecting your expensive equipment. Dell D220p 01 Power Supply Pinout 2
The Dell D220P-01 will not output 12V power simply by plugging it into a wall outlet. It requires a "turn-on" signal, just like an internal ATX power supply. Locate (the Remote/PS-ON wire). Locate any Ground pin (Pins 5, 6, or 7).
Once the connection is made, the internal fan should spin up, and you will measure 12V across the power pins. Safety and Conversion Tips This is the control pin
The D220P-01 is a fan-cooled unit. Ensure the intake and exhaust vents are not obstructed when mounting it in a custom enclosure or under a desk.
These are the GND (Ground) pins, completing the circuit for the 12V rails. The Dell D220P-01 Connector Overview ⚠️ While Dell
This pin is typically used for "Power Good" signaling or sensing by the Dell motherboard. In most DIY scenarios, it remains unused. Technical Specifications
