Wiring UBS3.0

Wylis · 29 Nov 2010 at 21:57

My new case (Lian Li PC-A77F) comes with 4 x native USB 3 ports on the front.
The motherboard, Crosshair IV Formula, only has two headers for USB 3.

So my question is, how do I wire up the final 2 ports?
Do I need to get a PCI-e USB 3 card and connect some outputs to the front of the case?

Any assistance gratefully received.

Anyone?
My Google-fu is apparently too weak to assist me with this one...
Any pointers/links/anything will be appreciated.

There's only a header for two ports, so an additional card is the only option.

Do you really need four front-mounted USB3? Or is it just a case of "they're there, so I want 'em connected"?

(I'm a bit like that, to be honest ^_^)

yeah, mate- it has 4, so I want to use all 4...

That board has 5 internal USB connectors. Each set of pins does 2 USB ports apart from one which doesnt have as many pins in it. None of the internal pins are USB 3 though

^^^^^^Done from memory as I was looking at that board a week or two ago.

Do you know how I can work around this then, please, mate, as I am really struggling, and google doesn't seem to be my friend on this issue...

There is no workaround. If you want to use them at USB 3.0 speed's you need to buy a add on card.

This is it really, that or just use them as USB 2.

I've also got this problem.
I saw this a few days ago and am trying to hound a couple down for my PC-A77F as well:
