Sure, I'm here to assist! What seems to be the issue you're facing?
The ASUS Prime Z590-P supports all front I/O ports from Corsair iCUE 4000X RGB Mid-Tower ATX cases. Yes, it works with USB Type C.
The board is compatible with USB 3.2 Gen 1 Type C. Check the manual for the header position.
Great job! Let me know if you need anything else.
