PCIe 4x USB 3.2 Gen 2 Card

This ARCTIC expansion card adds a single USB Type-C port running at up to 20 Gbps through a PCI Express 4x slot. It uses the ASMedia ASM3242 controller and supports the USB 3.2 Gen 2x2 standard while remaining backward compatible with USB 3.0 and USB 2.0 devices. The card works with Windows 10, Windows 11 (32-bit and 64-bit), macOS and Linux without extra drivers.

Desktop builders needing one 20 Gbps Type-C port

Suits anyone adding a single high-speed USB-C connection to a desktop that has a free PCIe 3.0 4x slot. Not for buyers who need multiple ports, internal front-panel headers or a different bracket style, because the card provides only one external Type-C connector.

Requires PCIe 3.0 4x slot for full speed

The motherboard must provide a PCI Express 3.0 4x slot to reach the advertised 20 Gbps throughput; slower slots will reduce performance. A 20 Gbps Type-E cable and a matching 20 Gbps drive enclosure are also needed to realise the maximum transfer rate.

Questions about this item

How do I confirm the ASM3242 card is delivering 20Gbps after installing it in a PCIe 3.0 4X slot?

Connect a 20Gbps USB 3.2 Gen 2x2 device using a 20G Type E cable and verify the link speed reaches 20Gbps in the OS device manager or benchmark tool.

What comes with the expansion card and what must I purchase separately to reach full speed?

The card itself is included; a 20G Type E cable and a 20Gbps HDD enclosure are required separately to achieve maximum performance.

Should I choose this card for a Windows 10 64-bit desktop or a Linux system to get 20Gbps Type C connectivity?

Both Windows 10 64-bit and Linux are supported; ensure the motherboard has a PCIe 3.0 4X slot to enable the full 20Gbps rate.
