Hallo Das Mainboard verfügt über eine interne Schnittstelle um eine Thunderbolt Karte von AsRock zu verbinden. "1 x Thunderbolt™ AIC Connector (5-pin) (Supports ASRock Thunderbolt™ 3 AIC Card R2.0 only)" Beschreibung: "Thunderbolt 3 is no longer limited to certain chipset, ASRock is the first motherboard manufacturer to skillfully implement the Thunderbolt 3 technology onto AMD X570 motherboards. All you need is a Thunderbolt 3 AIC R2.0 card! *1: Only three TB3 devices can be detected. *2 : Some USB 3.2 Type-C devices will cause system reboot after wake up from S3/S4. *3 : Cannot light up the TB3 monitor after wake up from S3/S4, re-plug the cable is needed. *4 : Does not support Thunderbolt 3 PCIe graphics card box." Das wäre dann die Karte: https://www.asrock.com/mb/spec/product.asp?Model=Thunderbolt%203%20AIC%20R2.0 Grüsse
