What connections will let you know if it is the motherboard or the fan or even the power button?

We are building a computer. I would like to know if the power supplies fan will work if it is plugged into to motherboard and the front on button.

What connections will let you know if it is the motherboard or the fan or even the power button.

Every system board has one or a pair of connections to provide electrical power from the power supply to the system board and to other components that receive their power ports and expansion slots coming off the system board Electricity travels over the system board on the buses, each bus has wires, or lines designated to carry voltage This explanation should describe the power connection to the motherboard Try the power supply on another board and check the results.
