Optiplex 3080 AC Adapter
I didn't encounter a power adapter with three pins before. What kind of power supply are you connecting it to? I own a PC backup battery that uses regular outlets.
Power adapters like that are quite common. From this selection, you'll see this adapter matches the same input as the one listed;
https://www.dell.com/en-us/shop/adapters/ar/7683. It's known as an IEC C5 connector. I think you're dealing with the micro version of the Dell Optiplex 3080? One side connects to the wall, the cable from the wall goes into the adapter, and the other end of the power brick fits into the back of your prebuilt's power input—specifically the port on the far left corner shown in the picture. Moved the discussion from the Systems section to the Power Supplies section.
Yes, Dell. The PC doesn't include a cord that connects to the wall, only one that exits from the computer. I plan to look for one tomorrow at a location.
Are you certain you're referring to the Dell Optiplex 3080 Micro? If so, the PC lacks a standard cord for wall plug-in. You might want to check options like the IEC C5 power cord to match your outlet type.
