Question JUSB2 and USB 3.0

[Amphora]

I've just recently built a computer and my MOBO only has a jusb 2.0 and I only have a USB 3.0. They don't fit so do I need to get a converter to make them fit? I'm also guessing this is the reason to why none of my USB ports will work.

Do you mean case has only USB3 ports ? If so, only way to have real USB3 is to ad PCI/PCIe USB3 card. Something like this https://www.amazon.com/StarTech-com-Port-SuperSpeed-Adapter-Power/dp/B00AWP9LMG
To use them as USB 2 you could get something like this https://www.amazon.co.uk/Akasa-AK-CBUB19-10BK-USB-Adapter-Cable/dp/B00BQ8A6N6

That model will not provide internal USB 3.0 ports.

I have a new case with USB 3 ports and USB2 ports. I bought this card to connect my USB 3 ports on the front case and some on the back also. https://www.newegg.com/model-orico-pvu3-5o2i-pci-express-to-usb-3-0-card/p/14G-0001-00017
