Thunderbolt 3 support is available on the Supermicro X11SPA-TF model.
The documentation doesn't mention Thunderbolt support for this motherboard. Other sellers claim it does, but ASUS.com lists it as unavailable. Using third-party add-in cards isn't ideal and may cause issues. Productivity could decline if you go this route. For more details on Thunderbolt and audio topics, egpu.io and AVIdiscussion are helpful resources.
Thanks for your message. It seems you were confident about the Thunderbolt header but later realized it wasn't there on the data sheet or visible in the photos. You mentioned uncertainty about the issues you faced, possibly related to a delay in Supermicro's TB3 add-in card release. Let me know if you'd like help clarifying further.
