TAA-compliant.

## Long description

The StarTech PCIe 3.0 USB 3.2 Gen 2 4-Port USB-A Expansion Card (P10Q4A-USB-CARD) adds four external USB-A ports to a desktop or workstation through a PCI Express slot. Each port is driven by an independent controller based on ASMedia ASM3142/ASM2812X chipsets and supports USB 3.2 Gen 2 (10 Gbps) transfer rates. The card installs into PCIe 3.0 x4, x8, or x16 slots and includes a pre-installed full-profile bracket. A built-in SATA power connector provides auxiliary power when motherboard supply is insufficient. The card is TAA-compliant and available in red, weighing 0.094 kg with compact dimensions suitable for most tower systems.
Advantages
This internal PCIe USB expansion card delivers dedicated, per-port bandwidth so each USB-A connection can achieve up to 10 Gbps without sharing a single controller. The presence of four independent controllers reduces bottlenecks when multiple high-speed devices are connected simultaneously. Auxiliary SATA power support stabilises performance for bus-powered devices by supplying up to 5V 2A (10W) per port. The plug-and-play compatibility with Windows, macOS and Linux simplifies installation and integration into existing systems.
Suitable for
Transferring large files to and from external SSDs and HDDs
Real-time editing of high-resolution photos and video from external storage
Connecting high-speed USB video capture devices and tethered cameras
Using USB-based network adapters for high-throughput networking
Charging and syncing smartphones, tablets and portable devices

How to use
Power down the computer, open the case and insert the card into an available PCIe 3.0 x4 (or larger) slot. Secure the bracket, connect the optional SATA power cable if your devices require additional power, and close the case. Boot the system; the card is recognised by most modern operating systems without additional drivers. Connect USB-A devices to the external ports. For maximum throughput, connect each high-speed device to a dedicated port and ensure the host system supports PCIe 3.0 bandwidth.
Usage recommendations
For sustained high-speed transfers, use USB 3.2 Gen 2 compatible cables and devices, keep the SATA auxiliary power connected when powering bus-powered peripherals, and install the card in a PCIe slot that provides sufficient lanes (x4 or higher). If multiple high-throughput devices are used simultaneously, verify the host platform provides adequate PCIe bandwidth and cooling to maintain consistent performance.
