Description

StarTech PEXUSB3S42V 4-Port USB 3.0 PCIe Expansion Card

Overview

The StarTech PEXUSB3S42V provides a robust solution for expanding your system's connectivity by adding four independent USB 3.0 ports. This PCIe expansion card is designed for workstations and servers requiring additional high-speed USB interfaces for peripherals, external storage, or specialized devices. The PEXUSB3S42V leverages a SATA or LP4 power connector to ensure stable power delivery to connected devices, crucial for demanding applications. It supports the USB Battery Charging specification for Apple devices, enabling faster charging of iPhones and iPads. This card is ideal for environments where multiple USB devices need to operate simultaneously without performance degradation, such as in video editing suites, data acquisition systems, or industrial control setups.

Compatibility

This PCIe expansion card is compatible with any motherboard featuring a PCI Express slot. It supports PCIe 2.0 specifications, ensuring broad compatibility with most modern desktop computers and servers. The card is designed to work with standard USB 3.0 (also known as USB 3.2 Gen 1) devices, offering backward compatibility with USB 2.0 and USB 1.1 peripherals. It is compatible with Windows operating systems, including Windows 11, 10, 8.1, 8, 7, and Server versions. For surveillance systems, this card can be used to connect multiple external hard drives for NVR storage expansion or to interface with specialized USB-based capture devices.

Installation Notes

Installation requires opening the computer chassis and inserting the card into an available PCIe slot. A SATA or LP4 power connector from the system's power supply unit must be connected to the card for optimal performance and USB Battery Charging functionality. 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). Relative humidity should be maintained between 5% and 85% RH (non-condensing).
