Product information

Description

The StarTech.com PEXUSB312C3 is a PCIe expansion card that adds two USB-C (10Gbps) ports to a desktop or server by occupying a PCI-Express slot (PCIe Gen3 x4). Powered by the ASMedia ASM3142 chipset, the card supports USB 3.2 Gen 2 (also known as USB 3.1 Gen 2) and is backward compatible with USB 3.2 Gen 1 (5Gbps) and USB 2.0 (480Mbps). It includes an optional SATA power connector for high-power devices and ships with both standard-profile and low-profile brackets for different system form factors.

Advantages

This PCIe USB-C card delivers up to 10Gbps per port for faster transfers with external SSDs and other high-speed peripherals, while maintaining compatibility with older USB devices through adapters or cables. The use of the ASMedia ASM3142 chipset ensures USB 3.2 Gen 2 performance, and the included SATA power option allows support for devices that require additional power. Cross-platform driver support covers Windows, macOS and Linux systems.

Suitable for (tasks / use cases)

Adding high-speed USB-C ports to a desktop or server
Connecting external NVMe/SATA SSDs and high-performance storage enclosures
Using modern USB-C peripherals while retaining compatibility with existing USB-A devices via adapters
Upgrading small form-factor systems using the low-profile bracket

How to use

Power down the computer and unplug it from the mains. Install the PEXUSB312C3 into an available PCIe Gen3 x4 (or larger) slot, secure the card with the bracket screw and attach the appropriate profile bracket for your case. If connecting high-power devices, attach a SATA power cable from the power supply to the card's optional SATA power connector. Reconnect power, start the system, and install any required drivers if the operating system does not automatically recognize the card. Connect USB-C devices using compatible cables or adapters.

Usage recommendations

For optimal performance, connect high-speed storage devices using USB 3.2 Gen 2-compatible cables and ensure the card is installed in a PCIe x4 or higher slot.
