I upgraded my hard drive to a SATA II 3.0 GB per second hard drive, and I don't have a cable that connects the SATA port on the mobo to the port on the hard drive. However, there's also a SATA cable coming out of the power supply that will connect to the hard drive.
My question is: which one do I need or do I need both of these?
Power supply -> Hard Drive
Motherboard -> Hard Drive
Much thanks for your help.
