Razer Core X and a gaming PC?

Hi all, I am a complete novice at this and go easy. I came across a new Core X at a bargain price. It comes with a USB-C connector. If I put my NVIDIA graphics card in the Core X and connect to my PC, well, the PC doesn't have USB-C. What's the best way of connecting? A USB-C card for the PC or something else? Thanks, Dave.
