This is the Gigabyte Maple Ridge Thunderbolt 4 add-on card for PCI Express. It will add Thunderbolt 4 to compatible Gigabyte motherboards.

Like new condition - includes the installation guide, and all of the cables (some of which are still in their original packaging):

-2x Mini-DisplayPort cable

-1x Thunderbolt Header cable (5-pin)

-1x Thunderbolt Header cable (3-pin)

-1x USB 2.0/1.1 Header cable

Gigabyte uses proprietary headers to connect Thunderbolt to their motherboards, so this is one of the few officially supported Thunderbolt add-on cards for Gigabyte motherboards.
