StarTech PEXUSB3S44V 4-Port USB 3.2 Generation 1 PCI Express Expansion Card Black

The StarTech PEXUSB3S44V is an internal USB expansion card that adds four independent USB 3.2 Gen 1 ports to a desktop computer. It connects via a PCI Express 2.0 interface directly to the motherboard. The card features four dedicated 5 Gbit/s channels, providing an aggregate bandwidth of 20 Gbit/s across the host interface. Unlike standard cards that share a single controller, this architecture ensures each connected device operates on its own data path. Integrated UASP support improves transfer efficiency when using compatible storage enclosures, allowing high-throughput peripherals to operate simultaneously without performance loss.

The card features four rear-mounted USB Type-A ports. Internal power is supplied through SATA or LP4 Molex connectors to maintain stable voltage for bus-powered devices. The Renesas/NEC µPD720202 chipset manages data flow. Both full-height and low-profile brackets are included for installation in standard or slim chassis. It is compatible with Windows 10 and various Linux distributions; drivers are included for setup.
