Asus just announced its latest ThunderboltEX 4 Add-on card for any PC builder looking to add Thunderbolt 4 connectivity to your PC. The add-on card can deliver up to 100 watts of power and features two Thunderbolt 4 ports.

The card’s speciality is that it allows for USB-C monitors without connecting a power adapter, while the Thunderbolt 4 ports can also support DisplayPort 1.4 passthrough. The card will give your PC full Thunderbolt 4 connectivity and uses the USB Type-C format. The only catch is that the connected PC needs to use an ASUS motherboard that features a Thunderbolt Readiness header.

The header will provide timing and other low-level system commands to the card. The motherboard will also need to have a USB 2.0 slot, a PCIe 3.0 x 4 host interface, and an extra 6-pin PCIe power input.
