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.

If the fan twitches and stops, you have a short or the PSU is in "latch-off" mode. Unplug AC, wait 30 seconds, and try again. Before hacking or rewiring the power adapter, it
