Product information

Description

The StarTech PEXUSB312C3 is a PCIe expansion card that adds two USB-C ports with USB 3.2 Gen 2 (10 Gbps) performance to a desktop or server. It installs into an available PCI-Express slot and uses the ASMedia ASM3142 chipset to provide higher data throughput and support for modern high-speed USB peripherals. The card includes full-height and low-profile brackets and provides up to 15 W per port for higher-power devices.

The card is compatible with Windows, macOS and Linux environments and is covered by a two-year manufacturer warranty.

How to use

Power off and unplug your computer, then install the card into an available PCI-Express slot and secure it with the bracket screw. If you need to supply additional power to connected devices, attach a SATA power cable to the card's optional SATA power connector. Reassemble the computer and power it on. Install any required drivers for your operating system if they do not load automatically. Connect USB-C devices using appropriate cables or adapters; the ports will operate at USB 3.2 Gen 2 speeds when used with compatible devices.

Usage recommendations

Use quality USB-C cables rated for 10 Gbps to achieve full USB 3.2 Gen 2 performance.
