He flipped the heavy black brick over, squinting at the fine print. No diagrams. No legends. Just a sleek, uncaring plastic casing. 14 minutes of breathable air remained.
Understanding the precise is critical before performing any hardware modifications, as miswiring this proprietary connector can permanently damage your components or create a short circuit. Key Technical Specifications
(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 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.
compared to the standard PCIe spec, which can cause immediate hardware damage. Common Uses: This power supply is popular for eGPU setups Dell D220p 01 Power Supply Pinout 2
Isolate the and the Braided shielding , as they are not required to enable power and can cause short circuits if left exposed.
Viewed from the wire side (looking into the back of the connector where wires enter). Locking clip on top.
Whether you are reviving a vintage Optiplex, building a low-cost bench supply, or learning ATX power supply basics, this guide should serve as your definitive reference. Always observe safety: capacitor discharge, insulation, and proper fusing.
If you are converting this PSU for hobbyist use (powering LED strips, charging batteries, testing motors), here is the correct way to access all outputs: He flipped the heavy black brick over, squinting
If you are searching for , you are likely staring at the smaller 6-pin or 4-pin secondary connector and wondering:
The Dell D220P-01 utilizes an 8-pin Molex-style layout. When looking directly at the front face of the male plug (the cable end coming from the power brick) with the locking clip facing upwards, the pin positions run from Pin 1 to Pin 8.

"Proposed revision," Elias read the forum note aloud. "Rearranged sensing lines. If you jumper it wrong, you don't just get no power. You feed 12 volts into a 5-volt rail and fry the capacitators. Spectacularly."
