Seven-port USB 3.1 expansion card

The EN-Labs PCIEU34ACS20 adds one USB-C and four USB-A external ports plus an internal 20-pin header for two front-panel ports, all running at up to 5.0 Gbps. It targets desktop builders who need more high-speed connections for drives, peripherals or front-panel upgrades.

Single PCIe slot with SATA power

The card occupies one PCIe slot and draws auxiliary power from a 15-pin SATA connector, so no extra power supply cables are required. A full-profile bracket secures it in standard rear I/O openings, freeing motherboard headers for other devices.

Dual-chipset design with UASP support

Dual controllers handle the seven ports and enable UASP for faster bulk transfers with compatible enclosures. The 5.0 Gbps ceiling suits external SSDs and hard drives, while the internal header serves front-panel USB 3.0 needs; bandwidth saturates when multiple high-throughput devices run simultaneously.
