Motherboard does not support usb 3.0

MrMitchMan04 · Apr 18, 2017

Hello,

I have a usb 3.0 connector that will not attach to my motherboard because my motherboard doesn't have a spot for the usb 3.0 connector to go in. I already plugged in a usb 1 cable thing and I don't know if that will do that job or not.

Also, the usb 3.0 cable came with the case. I have a feeling it just connects the CASE'S usbs to the motherboard. BUT there are already usb ports ON my motherboard, so cant I just use those?

Thanks so much!

No, MB side of connectors is different for USB2 and USB3. What you could use is an adapter. https://www.amazon.com/Silverstone-Internal-19-Pin-Adapter-G11303050-RT/dp/B00B1RM5YU
Small part goes to USB2 port on the MB and in the larger side you can connect that case USB3 connector.

^And yes, you can use USB ports that you have on back panel of motherboard.

Another alternative would be a pcie usb 3.0 card with an internal usb3 header on it. It would be closer to usb3 speeds (and would add a couple ports on the back), but you would probably need a usb3 header extension cable to go with it so it's a more expensive option than the 2.0 to 3.0 adapter above

which motherboard do you have make and model, odd that it has uSB 3 but not a header for a cable to be connected, in any case if that is true, you could get a USB2 header converter to USB3, but that USB port on the case (assuming front of pc) would only act like a USb2

DRagor :

Wait so I CAN use the back usb ports on the motherboard without an adapter? Just reassuring this because there are a few conflicting answers to that question.

MrMitchMan04 :

Yes, adapter is only necessary if you want to use front ports on your case. Back ports on mobo will work either way.

the back ports in blue showing thru the back plate are directly connected to your PC and will function as usb3 ports
the header is for the front usb 3 ports.

Yes, of course, your memory stick has to be USB3 too or it will not run at that speed.
