Connect the to one of the Black wires (Ground) .

: Because it provides 18A, it is recommended to join all three +12V (White) wires and all three Ground (Black) wires together if you are using it for high-current applications like eGPUs or LED strips to prevent individual wires from overheating. When the blue signal wire is grounded, the

Unlike a standard computer power supply that requires a motherboard, the D220p-01 can be turned on externally for bench testing or custom projects.

The 8-pin connector on the D220p-01 does not follow standard ATX conventions. Instead, it utilizes a proprietary configuration that provides a single, high-amperage Pinout Configuration (Standard 8-Pin Cable) Dell D220P 01 Power Supply Wiring | Pin

PW-OK only goes high after the main rails (+3.3, +5, +12) stabilize (100–500ms). If PW-OK remains low, the PSU has a fault (bad capacitor or overload). Recap: The D220P-01 is notorious for bulging 1000µF, 16V capacitors on the secondary side after 10+ years.

To bypass this safety feature and jump-start the power supply for standalone use, you must interconnect the remote logic wires:

Includes Over Voltage (OVP), Over Current (OCP), and Short Circuit Protection (SCP). Modification & Usage Tips

On the ATX side, you have no dedicated sense pin. You must solder a jumper on the adapter board between the Dell’s Pin 11 (Brown) and any +3.3V line (e.g., Dell Pin 12 Purple). Failure to do this results in 3.3V drifting to 3.8V or higher, frying chipsets and RAM.
