ive just put all my components into my case and just about to boot it up when i realize that there is nothing connected into my usb ports on my motherboard i check my power supply for the cable but i cant seem to see one that looks like it. i check my cases cables and there isnt any as well. does this mean i wont be able to use my usb ports at the front of the case? or even my usb Ports as there wont be any power running to it? My case is Corsair Carbide spec-03 and my motherboard is a gigabyte 990-fx
