We bought a nzxt h510 case and a msi mpg x570 gaming plus motherboard. When connecting every cable, one cable which was already mounted on the case was left without a socket, the USB 3.1 cable. The motherboard has a 3.2 socket but it's a completely different shape. Is there something we're missing here or do we need some kind of adapter? Dunno if it's a dumb question, this is our first build
