Building my first PC with the Helios case and the Z390-e Motherboard.


The USB wiring from the CPU takes up one nine pin socket on bottom edge of motherboard.
The wiring loom has two 20 pin USB plugs but there is only one 20 pin socket on motherboard.

Only two out of the four front top USB sockets work.
Changing the position of the nine pin to the other side of the 20 pin makes the opposite pair at the top front work.

Where, if anywhere, do I plug the spare 20 pin USB or do I need a 20 pin to nine pin adapter?

Bottom line is how do I get four working USB ports on the front top of case?
