StarTech.com USB C SuperSpeed PCIe Card PEXUSB321C Red 20Gbps 4 Lane

Description

Product Overview

The StarTech.com USB C PCIe card is engineered to bring the latest USB‑C connectivity to desktop computers that lack native support. Built around the high‑performance ASMedia ASM3242 controller, the card utilizes a PCIe 3.0 x4 interface to achieve true 20 Gbps SuperSpeed data rates, matching the specifications of USB 3.2 Gen 2×2. The card measures a compact 2 × 3.1 × 0.9 inches, fits easily into a standard or low‑profile slot, and is finished in a striking red chassis that stands out in any system build.

Beyond raw speed, the card supplies up to 15 W (5 V @ 3 A) of power through its USB‑C port, enabling rapid charging of smartphones, tablets, and other peripherals without the need for an external charger. Compatibility spans Windows 8 and newer, Linux distributions, and macOS, with drivers automatically installed on most modern operating systems. The card also supports legacy USB 3.1/3.0/2.0 devices, ensuring seamless integration with a wide range of accessories.

Usage

Designed for power users, content creators, and gamers, this expansion card excels in environments where high‑bandwidth data transfer and fast device charging are essential. Connect external NVMe SSD enclosures, high‑resolution docking stations, or 4K video capture devices to take full advantage of the 20 Gbps pipe. The card’s robust power delivery makes it ideal for charging laptops or powering bus‑powered peripherals such as external hard drives and audio interfaces.

In professional studios, the card can serve as a reliable backbone for audio‑video workflows, allowing editors to move large media files between storage arrays with minimal latency. In home offices, it provides a clean, single‑cable solution for connecting monitors, peripherals, and power to a laptop dock, reducing cable clutter and simplifying workstation setups. The low‑profile bracket ensures the card fits in compact cases, making it suitable for both full‑tower and mini‑ITX builds.
