Dell D220p 01 Power Supply Pinout 2 -

The Dell D220P-01 is a versatile power supply that offers reliable 12V output for a variety of projects. By following the pinout described above and applying the power-on signal, you can unlock its full 220W potential.

You must identify Pin 5 (Ground) and Pin 8 (Signal/Remote).

The (often referred to as the DA-2 series) is a popular 220W power supply brick originally designed for ultra-small form factor (USFF) Dell Optiplex systems like the Optiplex 745, 755, and SX280 . Because it provides a substantial 12V at 18A in a compact, fanless package, it is widely used by hobbyists for eGPU setups, LED strips, and bench power supplies .

Dell D220P-01 (part of the DA-2 Series ) is a 220W external power supply used primarily for Ultra Small Form Factor (USFF) Dell Optiplex systems like the SX280, GX620, and 700-series. Technical Specifications 100–240V AC, ~4A, 50–60Hz. 12V DC at 18A (Total ~216–220W). Connector: Proprietary 8-pin Molex-style plug (4.20mm pitch). 8-Pin Connector Pinout The following pinout describes the female receptacle Dell D220p 01 Power Supply Pinout 2

: Modifying any power supply involves working with potentially lethal voltages, even when unplugged (capacitors can hold a charge for a long time). If you are not experienced and comfortable working with high-voltage electronics, do not attempt these modifications. Always:

To turn on the power supply without plugging it into an official Dell motherboard:

(typically Pin 6). When successfully jumpered, the LED on the brick will change from orange (standby) to green (active). Compatibility: This unit was originally designed for Dell Optiplex Ultra Small Form Factor (USFF) The Dell D220P-01 is a versatile power supply

Most power supplies were standard. ATX. AT. Easy. But Dell, in their infinite wisdom in the early 2000s, had decided to rewire the universe. The first pinout he found was for the D220P-00. It didn't match. The colors were different. The gray 'Power Good' wire was in the wrong house.

Unlike standard desktop power supplies that use an ATX 24-pin shorting method, the Dell DA-2 will not output any voltage on its main rails until its internal logic circuit is closed.

Some D220P-01 units omit pins 4 and 6, leaving a 4-pin connector (positions 1,2,3,5 only). In that case: Pin1=Purple, Pin2=Black, Pin3=Green, Pin5=Gray. The (often referred to as the DA-2 series)

Here is the for revision 2 of the D220P-01. (Revision 1 had slight differences in the sense wire – this is specifically for the D220P-01 REV:02).

Depending on your project, you will approach the pinout in one of two ways: mapping the physical female plug looking directly at the connector face, or identifying the internal wire colors after slicing open the insulated cable. 1. Front-Facing Connector Map (Looking at the Plug)

This is often a sign of overcurrent protection or missing +5VSB load. Ensure your jumper is secure. Also check if any output rail is shorted. The D220P-01 uses "latching" overvoltage/overcurrent protection – you must unplug AC for 30 seconds to reset.

Even with the correct pinout, you may encounter issues:
