I wonder if this would only work on MSI cards. Would love to use this for my G1 980ti.

It sound like a generic kit to me. By the description it would work with any graphics card with a HDMI output and a motherboard with a USB 3 header. I always hated those drive bay USB ports that are simply extension cables from the rear ports - it's cleaner looking to connect to internal header. If you can deal with an HDMI cable coming out the back of your case and looping right back inside and being run to the front, then this is for you.
