My Book 3 PCI card compatibility


I’m interested in a My Book 3 USB 3 external drive/s; but I’m concerned about compatibility with my ASUS P5K Deluxe Mother-board.

ASUS’s USB-3 PCI card is not listed, on their site, as being compatible with the P5K Deluxe, so I can’t help but wonder if a " third party" card will work, and offer “full” USB 3 compatibility, & performance?

I have one open PCI 16x card slot.
