StarTech P5Q4A-USB-CARD 4-Port USB A PCIe Card, 5Gbps

Add four external USB Type-A ports to a desktop or server without sacrificing throughput. The StarTech P5Q4A-USB-CARD uses a PCI Express 2.0 x4 interface and four independent controllers, allowing each port to operate at up to 5 Gbps simultaneously. That architecture matters when multiple peripherals, storage devices, or test tools need consistent bandwidth at the same time. The card includes internal SATA and LP4 power connections and delivers 5 V, 2 A per port for 10 W per port. That gives IT teams a more capable expansion path than basic USB add-in cards, especially in environments where power delivery and port concurrency affect user experience or test reliability. It is compatible with Windows, macOS, and Linux, and supports hardware platforms including Intel, AMD, and Apple Silicon. With a standard profile bracket pre-installed, this card is ready for straightforward deployment in systems that need dependable external USB-A expansion. It is a practical choice when the goal is to add capacity, preserve performance, and avoid the compromises of external hubs.
