the mother gets turned on
Check the power cable and the PSU.
if the motherboard is designed for the case fan you are using its best to plug it into the motherboard, this will free up a spot on the power supply. Otherwise as long as the voltage and amps are the same it doesn't really matter. If you try to plug it into both you will double the power of the fan and very likely fry the fan.
The power switch.
What happens is that when you press the power button it sends an electronic signal to the motherboard, the motherboard is designed to start the power-up routine when this signal is received so first it activates, then the BIOS becomes active and starts the various components of your computer. Once everything is started is displays the BIOS screen and then the Hard Drive is spun up and windows starts loading.
it powers up the computer which then lets all the functions in the computer work i.e motherboard
Without the mainboard, also called motherboard, your computer would not work... at all. Everything is hooked up to it from RAM to hard drive to CPU. The only hardware component it doesn't control is the power supply, but the power supply is also hooked up to the motherboard.

The older format, AT, will power up without a motherboard. ATX form factor needs motherboard connection to power up. However, for about $15 you can purchase a PSU tester that plugs onto the psu to allow it to power up without the motherboard. Try: dalco.com, or FRY's etc. Actually, ATX will start without a motherboard, or a 'PSU tester'. The ATX motherboard power connector will have 1 green wire, and several wires of other colours. Find a bit of lose wire, it doesnt need to be very long. Make sure both ends of the wire are stripped. Push one end of the lose wire into the 'hole' that the green wire connects to, then push the other end into any 'hole' that has a black wire leading to it . The PSU should start, and stop when you remove the lose wire. == ==
