What kinds of PCI express USB 3.0 cards would be compatible with my EVGA Z87 Classified motherboard? What specs should I be looking for?

Sorry for the delay
Had to release your post from filter

Sorry- my needs would be to add some additional USB 3.0 capacity. When adding using powered USB hubs I now get error messages with certain connections (XQD Card reader) that there isn't enough capacity (or something to that effect). I thought that adding capacity via PCIe card would work. Just want to check out compatability
