Surprisingly, Thunderbolt 4 is getting more and more popular among content creators and high-end users … so much so, manufacturers are producing Thunderbolt 4 add-on/expansion cards, including this new one from Asus, the ThunderboltEX 4
Taken from TPU … ASUS today rolled out the ThunderboltEX 4, an add-on card designed to give your PC full Thunderbolt 4 connectivity. The only catch here is that you’ll need an ASUS motherboard with a Thunderbolt readiness header (which provides timing and other low-level system commands to the card). Also needed a USB 2.0 header, of which you’re likely to have plenty. The card features a PCI-Express 3.0 x4 host interface, and can be installed on any PCIe slot, x4 or larger. A 6-pin PCIe power input is also needed, as Thunderbolt 4 is capable of up to 100 W of power delivery per port, enabling single-cable RAID enclosures and monitors.
The ASUS ThunderboltEX 4 card puts out two Thunderbolt 4 ports in the USB type-C physical format, each with 40 Gbps of bi-directional bandwidth. The card provides DisplayPort passthrough for each port. You connect your graphics card to the ThunderboltEX 4 using the included DisplayPort to mini-DisplayPort cables. The card supports DisplayPort 1.4 passthrough, so you can scale all the way up to 8K resolution on the connected monitors, if your graphics card is game. Under the hood, the card features an Intel JHL8540 “Maple Ridge” Thunderbolt 4 controller. The company didn’t reveal pricing.
