I ended up buying both of these items:

Fenvi T919

9pin USB Header Splitter 1 to 4 Female extension

https://www.amazon.com/Splitter-Extension-Motherboard-Converter-Multiplier/dp/B09F2M5YLF

I had to get the splitter due to only having 1 USB 2.0 header on the ASUS Rampage VI Extreme. Looking forward to a good out of the box experience. If this resolves my last issue of not having Wi-Fi, it will be worth it.
