(also known as the series) power supply uses an 8-pin connector that delivers 12V at 18A. This connector is physically similar to a standard 8-pin PCIe power plug but is wired differently and is not directly compatible with standard PC components. Pinout Configuration

The 8 pins are typically arranged in two rows of four. Looking at the connector (clip side up), the standard wiring specification is as follows: Description Used for signaling; short to ground to power on Ground (-) Common ground Ground (-) Common ground Ground (-) Common ground Remote Ground (-) Signal ground Main power output Main power output Main power output Key Modification Notes Switching It On: The power supply remains in "standby" mode until Pin 1 (Remote) is connected to a ground pin (such as Pin 4 or 5). Safety Warning:

plug this directly into a standard 8-pin PCIe slot on a graphics card. The physical keying may be similar, but the pin positions for 12V and Ground are often

compared to the standard PCIe spec, which can cause immediate hardware damage. Common Uses: This power supply is popular for eGPU setups

or powering RC battery chargers due to its high amperage and reliable 12V output.

Dell D220P-01 Power Supply Pinout Guide | Electrical Connector

The Dell D220P-01 is a highly sought-after external power brick, originally designed for the Dell OptiPlex SX280 and GX620 ultra-small form factor PCs. Because it delivers a substantial 220 watts of power at 12V, it has become a staple for hobbyists looking to power radio equipment, LED strips, or DIY electronics.

Understanding the pinout of the unique 8-pin "Y" connector is essential for safely adapting this unit for custom projects. The Dell D220P-01 Connector Overview

The power supply uses a proprietary 8-pin connector. Looking at the face of the plug (the side that connects to the computer), the pins are arranged in two rows of four. The physical layout often features a notch or a specific orientation to ensure it only fits into compatible Dell hardware. Detailed Pinout Configuration

To identify the pins, orient the plug so the locking clip or guide notch is facing upward. We will number them 1 through 4 on the top row (left to right) and 5 through 8 on the bottom row (left to right).

Pins 1, 2, and 3: These are the +12V DC output rails. They provide the main power to your device.

Pins 5, 6, and 7: These are the GND (Ground) pins, completing the circuit for the 12V rails.

Pin 4 (Remote/PS-ON): This is the control pin. To turn the power supply on, this pin must be shorted to Ground (GND).

Pin 8 (Status/Signal): This pin is typically used for "Power Good" signaling or sensing by the Dell motherboard. In most DIY scenarios, it remains unused. Technical Specifications

Before beginning a conversion, keep these electrical ratings in mind to avoid overloading the unit: Input Voltage: 100-240V AC (Auto-switching) Output Voltage: 12V DC Max Current: 18.0 Amps Total Power: 216 Watts (Nominal 220W) Efficiency: High-efficiency switching design How to Power On Without a PC Dell D220p 01 Power Supply Pinout 2

The Dell D220P-01 will not output 12V power simply by plugging it into a wall outlet. It requires a "turn-on" signal, just like an internal ATX power supply. Locate Pin 4 (the Remote/PS-ON wire). Locate any Ground pin (Pins 5, 6, or 7).

Connect a jumper wire or a toggle switch between Pin 4 and Ground.

Once the connection is made, the internal fan should spin up, and you will measure 12V across the power pins. Safety and Conversion Tips

🚀 Join Multiple WiresSince 18 amps is a high current load, do not rely on a single +12V wire. Solder all three +12V wires together and all three Ground wires together to distribute the load and prevent the wires from overheating.

⚠️ Check the ColorsWhile Dell usually follows standard conventions (White or Red for +12V, Black for Ground, Blue or Green for Remote), wire colors can vary by manufacturing batch. Always verify your pinout with a multimeter before connecting your expensive equipment.

Ventilation MattersThe D220P-01 is a fan-cooled unit. Ensure the intake and exhaust vents are not obstructed when mounting it in a custom enclosure or under a desk.

If you need help identifying the wire colors for your specific revision or want a wiring diagram for a 12V conversion, let me know!

I assume you mean the Dell D220p‑01 laptop power adapter (barrel plug) — here’s the pinout for its 7.4×5.0 mm DC barrel with center pin (typical for Dell laptops):

• Center pin (male, inner contact): +19.5 V DC (V+)
• Barrel outer sleeve: Ground (V– / chassis)
• No data/ID pin on the barrel itself — identification for Dell chargers is done inside the adapter connector or via a separate 3‑pin smart plug on some models; the D220p‑01 is a simple two‑contact output.

If you meant a different D220p‑01 part (e.g., an internal PSU board or multi‑pin connector), tell me which connector (photo or part label) and I’ll give the detailed pinout.

Troubleshooting Your D220P-01

If your Dell D220P-01 refuses to power on, use this checklist:

1. Check Pin 11 (Brown sense wire): Is it connected to a +3.3V source? If it’s broken or loose, the PSU will either shut down or overvolt.
2. Test PS_ON# voltage: With the PSU plugged in but off, measure voltage between Pin 18 (Green) and ground. You should see ~3.5V to 5V. If it’s 0V, the PSU’s standby regulator is dead.
3. Measure +5VSB on Pin 7 (Red/Black): Should be steady 5V ±5%. If it’s missing, replace the small electrolytic capacitor on the primary side (5VSB filter cap).
4. The "Click of Death": A single relay click followed by silence indicates a short on the +12VA or +3.3V rail. Test continuity to ground on Pins 9/10 and Pins 12-14.
