These kinds of boards always require proprietary connectors directly to a supporting motherboard and the image shows some extra pins next the power connector. So I suspect this card isn't any different
There was some hope that someone would make a USB4 expansion card that didn't support PCIe tunneling, which wouldn't need those extra pins. If this card isn't it, then literally the only interesting thing about it is that it doesn't use an Intel controller. Which really is a negative.
