Usb3 headers on Gigabyte 970A ud3p

Sun Sep 04, 2016 2:58 am

Hi all,
I just got one of those front panel Multi io things from eBay. It has 6 usb2 and 2 usb3.0 outputs. The usb2 stuff is going well, but the (alleged) USB 3 headers on the motherboard are 9-pin about a cm apart, while the plug is the now-standard 20-pin.

I looked for an adapter with two usb3 nine-pins going into a usb 19/20 pin header. There are a lot of cables that will reduce 20 to 9 for you, but that also reduces the port to usb2 operation, if I understand it aright.

The 19/20 port plug from the new panel looks like it is just two parallel 9pins joined together. There are separate cables to the front panel. I am seriously considering cutting very carefully through the plug to split it into two. Should I? Or are the pinouts assigned all over the place? How can I increase my chances of success?

I don't think you should go for it. Low chance of success!

The only way I would attempt cutting them apart would be if you compare the pinouts first and verify that they match up. I'd say the odds of a match are low, and the odds of damaging the plug while cutting it are high.

If you can't find a suitable adapter, your best bet is an aftermarket PCIe-based USB 3.0 adapater card with an internal 20-pin connector.

I have a very similar board and I ended up getting a PCIe card with extra USB3 type A and type C ports on it for expansion. Really happy I did it that way as they are rock solid with Windows 10.
The on-board USB3 ports were always giving me  issues under Windows 7/8/8.1 but seem to be 100% rock solid with Windows 10 since they have their standard USB3 drivers in that system.

Thanks for the input and talking me down from a high risk approach. I should have a pcie port to spare, but it may be blocked by my sound card's daughterboard (and the other one already blocked by double-width cooler on GPU). I might follow up with the seller. If I cut, I will post pics and results. Thanks again.

If you do decide to cut, at least verify the pinout first. If the pinouts don't match, it isn't high-risk... it is guaranteed to fail.

Depending on the connector design, you may be able to move pins around to match up the pinouts... can you post a pic?
