ASRock launches their Thunderbolt 4 Add-on Card for supported motherboards

This accessory supports ASRock motherboards with a “TBT Header” and includes two DisplayPort 1.4 headers to enable DisplayPort to Thunderbolt pass-through for compatible Thunderbolt monitors. The add-on card offers users two Thunderbolt 4 connections (with 40Gbps bandwidth) and USB PD 2.0 charging at up to 9V@3A (27W). 

With Thunderbolt 4, users can connect to their PCs using the PCIe, USB and DisplayPort protocols, with this AIC supporting daisy-chaining for up to five Thunderbolt devices. This add-on card uses Intel’s JHL8540 Thunderbolt 4 Controller and ships in a thin 3.3-inch by 4.1-inch form factor with a single-slot PCIe slot width. 

Sadly, ASRock did not reveal the pricing of this AIC. That said, this AIC should help Thunderbolt 4 become more commonly used within the mainstream PC market and be a popular add-on for custom PC building companies, especially those who create workstations.
