I need to know if I buy all of the parts for my computer will the parts come with cablle or wires to connect them to the motherboard or do i need to buy some wire?
When you buy components they will come with all the nessacary additional cables you may need. Expansion cards slot into the expansion slots on the motherboard and thus don't need any cables.
Things like graphics cards will require auxillary power (6 or 8pin) and these will be attached to your PSU. If not graphics cards usually come with molex to 6/8pin adapters.
Everything tends to just slot together (except power connectors) and thus you will not need any additional connectors.
THANKS!!!
