StarTech PEXUSB312C3 Internal PCI Express USB Expansion Card - 2x USB-C - 10Gbps - ASMedia ASM3142 - Red

The StarTech PEXUSB312C3 is a 2-port PCIe USB-C expansion card (USB 3.2 Gen 2, 10Gbps) featuring the ASMedia ASM3142 chipset. It adds two USB-C ports to desktop computers using a PCIe 3.0 interface to handle data transfers up to 10 Gbit/s. The card supports UASP, which improves performance with compatible storage devices by reducing CPU overhead. It functions in any desktop system with an available PCIe x2 slot or larger.

The board features a red PCB and measures 80 mm × 122 mm × 18 mm. To ensure it fits various cases, the package includes both full-height and low-profile mounting brackets. The card is compatible with Windows (versions 7 through 11), Linux (kernel 3.5 or later), and macOS (10.15 Catalina through 14.0 Sonoma). Most modern operating systems recognise the card automatically without requiring manual driver installation.

• ASMedia ASM3142 chipset: Manages dual-port data flow to maintain stable throughput during simultaneous transfers.
• Windows Server compatibility: Supports versions 2008 R2, 2012 R2, 2016, and 2019.
• macOS support: Compatible with versions 10.15 (Catalina) through 14.0 (Sonoma).
• PCIe 3.0 x2 host interface: Provides sufficient bandwidth to support the 10 Gbit/s speed of the USB ports.
• Two 10 Gbit/s USB-C ports: Adds two external connections to the rear I/O panel.
• 45 g unit weight: Lightweight design minimises physical strain on the motherboard expansion slot.
