Thunderbolt 3 add-in card

This ASUS ThunderboltEX 3-TR expansion card adds two Thunderbolt 3 USB Type-C ports and two Mini DisplayPort inputs to compatible ASUS Z490 motherboards via a PCIe 3.0 x4 slot. It delivers up to 40 Gbps transfer speed and supports 8K Ultra HD output. The bundle includes a 14-1 pin Thunderbolt header cable and a USB 2.0 cable for internal motherboard connections.

Builders with compatible Z490 boards

The card suits owners of ASUS Z490 motherboards that provide a PCIe 3.0 x4 slot and the required Thunderbolt header. It is not for users whose boards lack that specific header or the necessary PCIe lane allocation. Buyers needing Thunderbolt on other chipsets or platforms should look elsewhere.

PCIe 3.0 x4 interface requirement

The single specification that decides fit is the motherboard's PCIe 3.0 x4 interface paired with a 14-1 pin Thunderbolt header. Without both, the card cannot function. Verify your Z490 board provides these exact connections before purchase.
