: When the Blue wire hits the Ground loop, the LED indicator on the brick body will change from an amber/standby color to a solid green, indicating that a clean ~12.3V–12.4V signal is active across the White wires.
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.
| | Signal Name | Wire Color | Description & Critical Usage Notes | | :--- | :--- | :--- | :--- | | 1 | +12V (Rail 1) | White | Main +12V Power Rail. | | 2 | +12V (Rail 2) | White | Main +12V Power Rail. | | 3 | COM (Ground) | Black | Ground. | | 4 | PS_ON# | Green | Power On Control: To turn on the PSU, this pin must be connected to Ground (COM). This is typically done by a switch or by the motherboard. | | 5 | +12V_SB (Standby) | Purple | Standby Power: Provides a constant +12V at low current (e.g., 2A) whenever the PSU is plugged into AC mains, even when the main outputs are off. | | 6 | COM (Ground) | Black | Ground. | | 7 | COM (Ground) | Black | Ground. | | 8 | PWR_OK (Power Good) | Grey | Power Good Signal: This pin is pulled HIGH (+5V) by the PSU to signal to the motherboard that all power rails are stable and within specification. | Dell D220p 01 Power Supply Pinout 2
Silas hacked the proprietary connector off with a pair of wire cutters, exposing a bundle of thick wires. He took a deep breath, trying to keep his hands from shaking. He powered on the brick and began probing the exposed ends.
⚠️ WARNING: EXPERT MODIFICATION REQUIRED The Dell DA-2 plug looks physically similar to a standard 8-pin PCI-Express (PCIe) graphics card power connector, but their PINOUTS ARE ENTIRELY DIFFERENT. Plugging this adapter directly into a standard PC component or eGPU board without a custom translation adapter will instantly ruin your hardware via reverse-voltage shorts. : When the Blue wire hits the Ground
What are you trying to power? (e.g., an eGPU, an LED strip, or a picoPSU)
bottom row (with clip)
Combine the white wires for the positive terminal and the black wires for the negative terminal to handle the high current.
