Description

StarTech PEXUSB3S44V 4-Port USB 3.0 PCIe Expansion Card

Overview

The StarTech PEXUSB3S44V provides a robust solution for expanding system connectivity by adding four independent USB 3.0 (5Gbps) ports via a single PCI Express x4 slot. This card is essential for workstations or servers requiring multiple high-speed USB devices, such as external storage, high-resolution webcams, or specialized data acquisition hardware. Its independent channel design ensures each port operates at its maximum 5Gbps throughput without contention, making it suitable for demanding data transfer scenarios. The inclusion of both SATA and LP4 power connectors allows for direct system power integration, ensuring stable operation for power-hungry peripherals.

Compatibility

This PCIe card is compatible with systems featuring a PCI Express x4 slot (or larger, such as x8 or x16). It supports USB Battery Charging 1.2, enabling faster charging for compatible mobile devices. The chipset ID is Renesas/NEC PD720202, a well-established controller for USB 3.0 performance. It is designed for standard profile installations but includes a low-profile bracket for small form factor (SFF) chassis.

Installation Notes

Installation requires opening the computer chassis and inserting the card into an available PCI Express x4 or larger slot. For optimal performance and to power connected USB devices, it is recommended to connect either a SATA power connector or an LP4 power connector from the system's power supply to the card. The operating temperature range is 0°C to 50°C (32°F to 122°F), and storage temperature is -20°C to 60°C (-4°F to 140°F). Humidity should be kept between 5% and 85% RH.
