When unplugging a desktop computer, from where is it best to pull the plug?

Pulling the plug from the back of the computer is considered the best practice when unplugging a desktop computer because it minimizes the risk of damaging the power supply and the motherboard. By unplugging directly from the back of the computer, you ensure that you are disconnecting the power source cleanly without putting stress on the power cord or the wall outlet. This method also helps prevent accidental contact with the live parts of the electrical system.

There are considerations with the other options; for instance, unplugging from the wall outlet might expose you to more risk if the outlet is not easily accessible or if you have to reach over other devices, potentially leading to mishaps. Additionally, pulling the power cord from the wall could put undue stress on the cord itself, risking wear or damage to both the cord and the outlet. Thus, the best approach is to unplug directly from the computer itself when possible.
