Product information

Description

The StarTech PEXUSB3S4V is an internal PCI Express expansion card that adds four external SuperSpeed USB 3.0 ports to a desktop or low-profile computer. Based on the NEC uPD720201 controller, the card provides USB 3.2 Gen 1 (5 Gbit/s) performance per controller, backward compatibility with USB 2.0/1.x devices, and includes a SATA power connection to support higher-power USB devices. The card ships with a low-profile bracket to fit both standard and small form factor systems.

Advantages

This PCIe USB 3.0 controller supports UASP (USB Attached SCSI Protocol) for improved throughput and more efficient command handling compared with traditional USB Bulk-Only Transport, enabling significantly faster file transfers and reduced CPU overhead when used with UASP-capable devices and supported operating systems. The stacked, space-saving port layout exposes four external ports while allowing installation in compact systems. The integrated SATA power connector permits each USB port to supply higher current to bus-powered devices when connected to the computer’s power supply.

Suitable for

Adding multiple high-speed external USB ports to a desktop or small form factor PC
Connecting external storage enclosures, SSDs or HDDs for fast data transfer
Powering and connecting bus-powered peripherals that require up to increased USB current when SATA power is available
Upgrading older systems to USB 3.0 performance while retaining USB 2.0 compatibility

Key specifications

Interface: PCI Express (internal card)
Number of external ports: 4 SuperSpeed USB 3.0 ports (stacked layout)
Controller chipset: NEC uPD720201
Data transfer rate: up to 5 Gbit/s per controller (USB 3.2 Gen 1)
Protocol support: UASP (when used with compatible OS and devices)
Power: onboard SATA power connector to supply additional current to USB ports
Form factor: includes low-profile bracket for small form factor installations
Compatibility: supports a range of Windows desktop and server operating systems and Linux with appropriate drivers

How to use

Install the PEXUSB3S4V into an available PCI Express slot on the computer’s motherboard, using the supplied full-height or low-profile bracket as required. Connect the SATA power cable from the system power supply to the card’s SATA power connector to enable increased current output for connected USB devices. After hardware installation, boot the system and install any required drivers for your operating system; modern Windows and many Linux distributions include native support for the controller and UASP where applicable. Connect external USB devices to the stacked external ports for data transfer or device charging as supported.

Usage recommendations

For best performance with UASP, use UASP-capable external enclosures or devices and ensure your operating system supports UASP (for example, Windows 8/Server 2012 or newer, or recent Linux kernels). When connecting high-current devices, always attach the system SATA power to the card to allow each port to deliver the higher current levels safely.
