⚠️ WARNING: EXPERT MODIFICATION REQUIRED The Dell DA-2 plug looks physically similar to a standard 8-pin PCI-Express (PCIe) graphics card power connector, but their PINOUTS ARE ENTIRELY DIFFERENT. Plugging this adapter directly into a standard PC component or eGPU board without a custom translation adapter will instantly ruin your hardware via reverse-voltage shorts.
If you are looking for specific replacement parts, you can check compatibility on CPUMedics .
The D220P-01 is a popular platform for modifications, primarily to convert it into a variable voltage power supply or to adjust its built-in protection limits. While the connector is mechanically similar to an
Some revisions use White instead of Gray for PW-OK. Verify with a multimeter: It should be 0V when PSU is off, ~5V after PS_ON# is pulled low and rails stabilize.
To use the unit outside a Dell system, many users cut the connector and splice the wires.
Disclaimer: Working with power supplies involves high-voltage capacitors that can hold a charge for weeks. Always discharge the PSU and disconnect AC before probing. The author assumes no responsibility for damage to property or personal injury. | | 2 | Black | Ground | Main ground return
No, the output is fixed at 12V. However, you can modify the D220P-01 to output 24V, but this is an advanced modification that requires changing multiple components and is not recommended for beginners.
Includes OVP (Over Voltage), OCP (Over Current), SCP (Short Circuit), and OTP (Over Temperature) protections. Connector: Proprietary 8-pin DIN-style plug (DA-2 style). 8-Pin Connector Pinout
When looking straight at the end of the male connector attached to the power brick cable (pins oriented in two rows of four), the standard layout functions as follows: Pin Number Pin Name / Function Physical Key Shape +12V DC Rail 1 Pin 2 +12V DC Rail 2 Pin 3 +12V DC Rail 3 Pin 4 Reserved / Sense (No load) Pin 5 Ground (GND) Pin 6 Ground (GND) Pin 7 Ground (GND) Pin 8 REMOTE / Signal (Power On)
