PCIe X2 USB 3.2 Gen2 10Gbps Adapter

This PCIe X2 expansion card adds one external USB-C port and one internal Type-E header to a desktop PC. It uses the ASMedia ASM3142 controller to deliver up to 10Gbps bandwidth on both connectors. The card fits standard ATX cases with its included full-height bracket and requires no extra SATA power cable.

Front-panel upgrade for desktop builders

It suits anyone adding a modern front-panel USB-C connector or a high-speed rear port for external SSDs and docks. Buyers whose motherboard lacks a free PCIe slot or who need more than two added ports should look elsewhere. The board is backward compatible with USB 3.2 Gen1 and USB 2.0 devices.

Drops into x4, x8 or x16 slots

The physical X2 connector works in larger PCIe 3.0 slots without configuration. No auxiliary power means one less cable to route inside the chassis. Gold-plated contacts and built-in overcurrent protection help maintain reliable operation for connected storage and peripherals.
