Connect Case Cable to Mainboard

STEP 11: Connect Case Cables to Motherboard 

With the motherboard installed, it is time to connect the internal cables that run from the case.

Connect the Cables from the Case

It is difficult to give detailed instructions for this, because every motherboard and case is different. In general, you should have twisted cables for the speaker, case fan, hard drive light, power light, power switch and reset buttons. You may also have cables for USB ports if your case has them built in.

Your motherboard manual will have a detailed diagram on where to attach these. Follow the directions on where these go for a smooth installation. Make sure to attach the wires in the correct orientation, usually each set of wires has a ground so it is pretty easy to figure out which way they go.

If you are not using onboard video via the motherboard, then the next step is to install the video card into the proper slot.
