Dell D220p 01 Power Supply Pinout 2 Instant

The is an exceptionally popular AC-to-DC power brick used by electronics hobbyists, DIY makers, and Small Form Factor (SFF) PC builders . Originally designed as the DA-2 Series external brick for legacy ultra-compact Dell desktops—such as the OptiPlex SX280, GX620, 745, and 760 series —it delivers a massive 12V DC output at up to 18 Amps (216 Watts / 220W total power) .

Note: Inside the factory cable jacket, you will also find a thick braided metal shield. This acts as chassis ground and EMI shielding; it can be cut back and safely insulated if you are building a custom bench supply. How to Turn On the D220P-01 Without a Dell Motherboard When you plug the Dell D220P-01

Measure the voltage across the white (12V) and black (Ground) wires using a multimeter. It should read around 12.35V.

Most D220P-01 units include a small 4-pin square connector (often labeled "P4") for the CPU VRM. This matches the standard ATX12V connector electrically , but check the colors.

For further technical specifications, you can refer to detailed guides on Scribd or community discussions on eGPU.io for modification tips. Dell D220P 01 Power Supply Wiring Dell D220p 01 Power Supply Pinout 2

Power Supply Units (PSUs) are a critical component of any computer system, converting Alternating Current (AC) power from a wall outlet into Direct Current (DC) power that the system's components can use. The PSU connects to the motherboard via a specific connector, and the configuration of this connector, or pinout, varies by PSU model and manufacturer. The Dell D220p 01, like other PSUs, has a specific pinout that dictates how power is distributed to various components.

Dell D220P-01, often referred to as the DA-2, is a 12V DC power supply that originally powered OptiPlex USFF (Ultra Small Form Factor) PCs like the SX280, GX620, and 745 series. This 220W unit is highly valued by the DIY and eGPU (external Graphics Processing Unit) communities for its compact, fanless design and high current output. However, its 8-pin Mini-Fit Jr. connector has a pinout that is both mechanically and electrically . A standard EPS12V or PCIe power cable will not work and will cause damage if inserted . This guide provides the definitive pinout information for the D220P-01 along with essential usage and safety details.

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:

Because it uses a proprietary 8-pin connector rather than a standard ATX layout, understanding the exact is critical to safely jump-starting and converting this unit without causing a short circuit. Key Technical Specifications The is an exceptionally popular AC-to-DC power brick

Due to its high amperage (18A at 12V), the D220P-01 is frequently used for hobbyist projects, such as LED lighting, 3D printers, or radio equipment. Cut the 8-pin connector off the cable.

to power external desktop graphics cards via PCIe risers. Custom adapter kits allow you to map the DA-2 connector directly over to standard 6-pin or 8-pin PCIe graphics power plugs. When doing this, ensure your PCIe splitters strictly map the yellow 12V lines to pins 6, 7, and 8, and the black ground lines to pins 2, 3, and 4. Keep the remote lines isolated to prevent frying the graphics card logic board. 3. Custom LED and Display Drivers
