Product information

Description

The StarTech.com PEXUSB3S42V PCI Express Card Adapter adds four USB 3.2 Gen 1 (USB 3.0) ports to a PCIe x4-enabled desktop, using two independent 5 Gbps channels. The card supports UASP for improved transfer efficiency, includes optional SATA or LP4 power input to supply higher current to connected devices, and is backwards compatible with USB 2.0/1.1. It ships with a full-height bracket and a low-profile bracket for small form-factor systems and is backed by a 2-year StarTech.com warranty.

Advantages

Two dedicated host controller channels split the four ports into two independent 5 Gbps links, reducing bandwidth contention compared with single-bus designs and effectively providing up to 10 Gbps aggregate throughput. UASP support accelerates transfers and reduces CPU overhead when used with a UASP-capable enclosure and compatible OS. Optional SATA or LP4 power input delivers up to 900 mA per USB 3.2 Gen 1 port for bus-powered devices and the card supports USB Battery Charging 1.2 (Apple Mode) for faster charging of compatible Apple devices. The adapter provides backward compatibility with USB 2.0/1.1 and includes both standard and low-profile brackets for versatile installation.

Suitable for (tasks / use cases)

  • Adding multiple high-speed USB ports to a desktop PC
  • Improving transfer speeds for external SSDs or RAID enclosures with UASP support
  • Connecting and charging high-power USB devices that require additional power input
  • Upgrading small form-factor systems using the included low-profile bracket

Key specifications

  • Interface: PCI Express (PCIe x4)
  • Output: 4 × USB 3.2 Gen 1 ports (5 Gbps each, arranged as two independent channels)
  • UASP: Supported (requires compatible OS and enclosure)
  • Power input: Optional SATA or LP4 (Molex) connector; up to 900 mA per USB 3.2 Gen 1 port
  • Backward compatibility: USB 2.0 / 1.1
  • Form factor: Full-height bracket included; low-profile bracket included
  • Manufacturer: StarTech.com, MPN: PEXUSB3S42V, EAN: 0065030854597

How to use

Install the card into an available PCIe x4 (or larger) slot on a powered-off desktop motherboard, secure it with the bracket screw, and replace the case cover. If additional power is required for high-current devices, connect the system power supply to the card using the provided SATA or LP4 power connector. Install any necessary drivers provided by the operating system or StarTech.com. For UASP performance, connect the card to a UASP-capable enclosure and ensure the operating system supports UASP.

Usage recommendations

For best performance, use quality USB 3.2 Gen 1 cables (maximum recommended length 3 m), connect UASP-capable enclosures when possible, and provide the optional SATA/LP4 power connection for bus-powered high-current devices. Verify OS compatibility for UASP to realize the full performance benefits.
