ESTONE PCIE24A3C3.2 7‑Port USB 3.2 PCIe Expansion Card

Seven-port USB 3.2 expansion card

The ESTONE PCIE24A3C3.2 adds seven external USB 3.2 Gen 2 ports to a desktop PC or workstation through a single PCI Express slot. Four ports are USB Type-A and three are USB Type-C, providing broad peripheral connectivity for storage, input devices and accessories. The card fits PCIe x4, x8 or x16 slots and operates on Windows XP through Windows 11, Mac OS 10.8.2 and later, plus Linux Mint and Ubuntu 20.04. Driver installation is required for Windows 7 and earlier.

Sustained 10 Gbps bandwidth shared across seven

The card delivers up to 10 Gbps of aggregate bandwidth compliant with the USB 3.2 Gen 2 specification. Under continuous load the total throughput is divided among all active ports, so simultaneous transfers from multiple high-speed drives will share the available bandwidth. Actual transfer rates depend on the connected device capabilities and system PCIe lane configuration. The adapter handles data signals only and does not support video output or Thunderbolt protocol.

PCIe lane width and host controller limit total

A PCI Express 3.0 x1 link caps theoretical bandwidth at roughly 8 Gbps, which is below the card's 10 Gbps USB specification, so sustained peak rates require at least an x2 or wider link. The host controller manages all seven ports through a single upstream connection, making the PCIe slot generation and negotiated link width the practical ceiling for combined data flow. Backward compatibility with USB 3.0, 2.0 and 1.1 devices is maintained, but each device negotiates at its own maximum speed.
