Because it outputs a single, stable 12V rail inside a silent, fanless enclosure, it serves as an ideal external power source for eGPU (External Graphics Card) setups , high-current LED displays, radio communication rigs, and RC battery chargers. However, utilizing this power brick for custom projects requires bypassing its proprietary, keyed 8-pin connector.
The output connector is a proprietary 8-pin block (two rows of 4 pins). It is crucial to verify the orientation before testing. Dell D220p 01 Power Supply Pinout 2
By default, plugging the Dell D220P-01 into a wall socket will not produce 12V across the power lines. The internal circuitry remains in a low-power standby mode until it receives an explicit turn-on signal from the host device.
Before modifying the device, review the factory input and output specifications printed on the underside of the original chassis: D220P-01 (DA-2 Series) Dell Part Numbers (DP/N): M8811, N112H, Y2515, D3860, MK394 AC Input Voltage: 100V–240V AC (50–60Hz), ~4.0A max DC Output Power: 12V DC, 18A continuous rating Total Wattage: 216 Watts (commonly rounded up to 220W)
To force the power supply to turn on and deliver its full 18-amp capacity for standalone applications, you must complete the logic loop: [ 1 ] [ 3 ] [ 5 ] [ 7 ] 4
If your D220P-01 has a 2×2 square 4-pin connector with yellow/black wires only , it is standard +12V. If it has red/orange wires, it is NOT a CPU connector – it may be for powering an IDE drive or proprietary Dell riser card.

The brick terminates into a distinctive, proprietary 8-pin rectangular plug. Looking directly into the female holes of the power brick’s output plug cable (with the locking clip facing upwards), the pins are laid out systematically.

Measure the voltage across the white (12V) and black (Ground) wires using a multimeter. It should read around 12.35V.
Fan spins, voltages appear on all rails.
