Note: Some technical guides indicate that Pin 5 is the "Remote" pin and must be shorted to Ground to turn the unit on. Technical Specifications Input: 100–240V AC, 50–60Hz Output: 12V DC at 18A (216W–220W total)
Protection: Includes Over Voltage (OVP), Over Current (OCP), and Short Circuit Protection (SCP). Modification & Usage Tips
Turning it On: To enable the 12V output without a Dell system, you typically need to jumper Pin 5 (Remote) to Ground. Users often report the LED turning from orange (standby) to green (active) once properly shorted.
Wire Identification: If cutting the cable for a custom project, you will typically find three white wires (+12V), three black wires (Ground), a blue wire (Signal), and a red wire.
Compatibility: This unit is the standard replacement for Dell Optiplex models SX280, GX620, 745, 755, and 760.

7. Final Verdict
The Dell D220P-01 is a robust 220W unit but is dangerous for standard builds without modification. Its "Pinout 2" often refers to the swapped PS_ON/PW-OK lines or the secondary connector’s non-standard pin assignment. Always verify voltages with a multimeter before connecting to any device.
Best use cases:
- Replacement in original Dell OptiPlex.
- Bench power supply for 5V/12V projects (with added load).
- Parts donor (heatsinks, caps, fan).
Worst use case: Direct plug into an off-the-shelf ATX motherboard.
Disclaimer: Modifying power supplies involves risk of electric shock or fire. Only proceed if you understand mains voltage safety and discharge bulk capacitors.

The Dell D220P-01 (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 8-Pin Connector Pinout
The D220P-01 uses a proprietary 8-pin connector that is mechanically similar to an 8-pin EPS12V motherboard connector but uses a completely different electrical layout.
Important: Never plug this directly into a standard motherboard 8-pin header without modification, as it will likely cause a short circuit or permanent damage. Connector Pin Mapping (Female Receptacle View)
When looking at the female receptacle (on the device side) with the clip/fastener at the bottom, the pins are typically numbered and assigned as follows: Pin Number Description Typical Wire Color 1 +12V 12V DC Output (Rail 1) White / Red 2 +12V 12V DC Output (Rail 2) 3 +12V 12V DC Output (Rail 3) 4 Reserved Logic/Sense (Not usually used) Red / Black 5 Remote (PS_ON) Connect to Ground to Turn On 6 GND Ground / Negative (-) 7 GND Ground / Negative (-) 8 GND Ground / Negative (-) Source: Scribd Wiring Spec, Pinouts.ru. How to Power On the Unit
Unlike standard ATX power supplies that use a green wire for "Power On," the D220P-01 requires a specific signal connection to activate its 12V rails.
Identify the Signal Pin: In many variants, Pin 5 (Remote/Blue) must be shorted to any of the Ground pins (6, 7, or 8) to switch the unit from standby to active mode.
LED Indicator: When the power supply is plugged in but not "on," the LED on the brick is typically Orange (Standby). Once Pin 5 and Pin 6 are shorted, the LED should turn Green, indicating that 12V is now present on Pins 1, 2, and 3.
Alternative Wiring: Some users report that twisting the blue wire with a black ground wire is the simplest way to enable output for DIY projects. Technical Specifications Dell D220P 01 Power Supply Wiring
The Dell D220P-01 (DA-2 Series) is a robust, high-output 216W external power brick originally designed for ultra-small form factor (USFF) desktops like the Dell OptiPlex SX280.
