The new case that I am buying has USB 3 support. Great. But unfortunately, it is powered through a cord that goes to the back of the case which you are supposed to plug into an external port on the motherboard. I can do this, but I really don't want to. Is there an adapter I can get which is a USB 3 to a USB 3 motherboard header?
Also, in an unrelated issue, my motherboard has three PCIe x16 slots, but one runs at x8 and one at x4, while the main one runs at x16. I am planning to Crossfire my GPUs. Will one of them run slower if it's in the x8 slot?
Yup, that there is fine, it is 19pin for future reference, they weren't readily available on my build so I bought a drivebay unit and stripped it down,
Grab one and plug your case cables into it, and your done :-)
