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. == ==

A very useless motherboard
Not all - although most 'modern' computers do. Modern computers tend to be supplied with either an 'on-board' network adaptor or network card plugged into one of the slots on the motherboard. Older computers came without a network card, and needed additional hardware to connect to a network.
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.
motherboard is dere or not??

If you want computers just to communicate with each other. The answer for question would be yes.: Via Cat Cables :D
A wireless router is used, mainly, to transmit an internet connection to several computers in a household or business without wires.
The component that must be compatible with every other component of the computer is the motherboard. Your computer will not function properly without them being compatible.
