Description

StarTech P5Q4A-USB-CARD 4-Port USB 3.2 PCIe Card

Overview

The StarTech P5Q4A-USB-CARD provides four independent USB 3.2 Gen 1 ports, each capable of 5Gbps data transfer rates. This PCI Express expansion card is designed to add high-speed connectivity to workstations, servers, and industrial PCs, enabling the simultaneous operation of multiple demanding peripherals like external SSDs, high-resolution webcams, or specialized data acquisition devices without performance bottlenecks. The inclusion of four independent controllers ensures each port operates at its maximum potential, preventing shared bandwidth limitations common in other multi-port solutions. This card requires a PCIe 2.0 x4 slot or larger for full performance.

Compatibility

This card is compatible with Windows 7 and later, as well as Linux kernel 2.6.31 and later. It supports standard USB 3.0/3.1 Gen 1 devices and is backward compatible with USB 2.0 and USB 1.1 devices. It requires a motherboard with an available PCI Express x4 slot (or x8/x16 slot).

Installation Notes

Installation requires opening the computer chassis and connecting the card to an available PCIe slot. For optimal performance and to ensure full power delivery to all ports, an external SATA power connector (15-pin) or LP4 power connector (4-pin) from the system's power supply is required. The operating temperature range is 0°C to 50°C (32°F to 122°F), and storage temperature is -10°C to 70°C (14°F to 158°F). Relative humidity should be between 5% and 90% RH (non-condensing).
