Product information

Description

The StarTech.com PEXUSB311AC3 is a PCIe add-on card that adds one USB-C and one USB-A port to a desktop or server via a PCI Express slot. It provides two USB 3.2 Gen 2 ports (10Gbps per port) and supports UASP for improved transfer performance. The card is powered via the PCIe slot and includes an optional SATA power connection to supply up to 5V 3A (15W) to the USB-C port and up to 5V 0.9A (4.5W) to the USB-A port when additional power is required. The card uses an ASMedia ASM3142 chipset and is compatible with Windows, macOS and Linux; it ships with both full-height and low-profile brackets for installation in different system form factors.

Advantages

This PCIe card delivers 10Gbps USB 3.2 Gen 2 connectivity for both USB-C and USB-A devices, supporting backward compatibility with older USB standards. UASP support enables significantly faster throughput and reduced CPU overhead when connected to compatible hosts. The included SATA power input provides supplemental power for high-performance external storage and other power-hungry USB devices. The package includes full-height and low-profile brackets for simple installation in standard and small form-factor PCs.

Suitable for

Adding high-speed USB-C and USB-A ports to desktops and servers
Connecting external SSDs, HDD enclosures and RAID storage
Upgrading systems to support USB 3.2 Gen 2 peripherals
Mixed environments with legacy USB-A and modern USB-C devices

How to use

Power off the computer and install the card into an available PCIe slot. If your external devices require additional power, connect the card's SATA power cable to a spare SATA power connector from the system power supply to enable supplemental power to the USB ports. Reassemble the system, power it on and allow the operating system to detect the new USB controller. Install drivers if required by your OS. Connect USB-C or USB-A devices to the exposed ports; when using UASP-capable devices on a compatible host, transfer speeds and efficiency will improve automatically.

Usage recommendations

For best performance with external storage, use high-quality USB 3.2 Gen 2 cables and enable UASP on supported operating systems (Windows 8 or later, macOS 10.8+, and modern Linux distributions). Use the SATA power connection when connecting power-hungry drives or multiple devices to ensure stable power delivery.
