Taichi X399 PCIe3 not detcting inserted card.

Hi all, my first post.
I have just built this machine to up grade from  my i7 2600 Asrock H77 Pro4 that has served me many years, my problem is moving the Blackmagic Intensity Pro https://www.cnet.com/products/blackmagic-intensity-pro-video-input-adapter-pcie-series/specs/ it is not detecting it in PCIe3, or any other cards for that matter, has anyone else had this issue?
