The StarTech.com PEXUSB312A1C1H is a PCIe USB expansion card for desktop users who need more high-speed connections: it adds two 10Gbps USB-A ports, one 10Gbps USB-C port, and a 5Gbps internal two-port USB header. It suits external-storage users and builds with a compatible PCIe 3.0 x4 slot.
Recommended For
- Desktop users who regularly move backups or video-editing files on external USB SSDs and need to add 10Gbps USB-A and USB-C ports through a PCIe slot.
- PC builders or upgraders who need an internal USB header for a front-panel hub or card reader, especially when the motherboard’s existing headers are occupied.
- Desktop owners with a compatible PCIe slot who want to add external USB ports to an older system without replacing the motherboard.
- Users connecting a mix of newer USB-C and USB-A accessories alongside older USB devices, who want those connections on one expansion card.
