I recently build a PC using Asus rog strix b550-f motherboard with 5900x. I haven't noticed before build this system is this board doesn't have a usb-c front panel header while my case have the connector. Now I looked this Cablecc USB 3.1 Front Panel Socket & USB 2.0 to PCI-E Express Card Adapter for Motherboard on amazon. In the review mentioned this card working on 3.0x2 mode. my current board already have a wifi 6 card and a video capture card on two pcie x1 slot. Not sure the spare pcie x16_2 slot can run on 3.0x2? or only run 3.0x1. Any help? Thanks.
