Dell D220p 01 Power Supply Pinout 2 |work| -

The (commonly known as the Dell DA-2 adapter ) is a highly popular, robust 220W external power brick . It delivers a massive 12V at 18 Amps , making it a prime choice for DIY projects, eGPUs, ham radio gear, and LED displays. However, because it uses a proprietary 8-pin connector and requires a remote turn-on sequence, understanding its exact pinout and wire color coding is essential to avoid destroying your hardware.

Once the , the internal logic tells the power supply to boot up. The LED indicator on the brick will turn solid green , and a steady ~12.3V DC will become accessible on the white wires. Practical Applications and DIY Tips 1. Distributing the Current Load

The secondary 6-pin connector (Pinout 2) is the master control center. Its Purple (5VSB), Green (PS_ON#), and Gray (PW-OK) wires are non-negotiable for proper operation. The main 20-pin connector only carries power rails. Dell D220p 01 Power Supply Pinout 2

The connector is a Molex-style, dual-row 8-pin interface. Understanding the difference between the (viewed looking directly at the face of the plug pins) vs the internal wire colors is crucial to safely operating the unit. Pin Mapping and Wire Specifications

The brick utilizes a custom 8-pin connector. Looking directly at the (or the wire-side orientation mapping), the official Dell D220P-01 Power Supply Pinout Guide on Scribd establishes the following specifications: Pin Number Internal Wire Color Pin Function / Signal Assignment Description Pin 1 Remote + (Sense Line) Used by the system to detect the power supply. Pin 2 Ground (GND / -) Negative power return channel. Pin 3 Ground (GND / -) Negative power return channel. Pin 4 Ground (GND / -) Negative power return channel. Pin 5 Remote Ground / PS_ON The control line used to toggle power delivery. Pin 6 +12V DC Output Positive 12V power rail. Pin 7 +12V DC Output Positive 12V power rail. Pin 8 +12V DC Output Positive 12V power rail. The (commonly known as the Dell DA-2 adapter

The is a 200-watt ATX-style power supply unit (PSU) that shipped predominantly with Dell Optiplex GX270, GX280, and Dimension 3000/4600 series desktops in the mid-2000s. While modest by today’s standards (12A on the 12V rail), this unit has found a second life among electronics hobbyists, retro PC builders, and bench-top power supply converters due to its compact size, reliable Delta Electronics construction, and—most importantly—its unique two-connector pinout.

Makers frequently reuse this power supply to run custom eGPUs, picoPSUs , 3D printers, LED strip lighting, radio equipment, or benchtop lab power systems. However, because it utilizes a proprietary, non-standard , you must understand its exact wiring pinout and remote turn-on configuration to use it safely. The Dell D220P-01 8-Pin Wiring Diagram
