5-Port USB 3.0 Expansion Card

This ESTONE PCIE23A2C card adds five USB 3.0 ports to a desktop computer through a PCI Express x1 slot. It provides two USB-C and three USB-A connectors for connecting additional peripherals. The card supports Windows 7 through 11 and Mac OS 10.8.2 or later with a driver installation.

PCI Express x1 Interface

The card installs into any available PCI Express x1 slot and is backward compatible with PCIe 2.0 and 3.0 motherboards. This single-lane connection determines the maximum aggregate bandwidth available to all five ports combined. No external power cable is required as the card draws power directly from the slot.

Sustained Transfer Behaviour

Each port can reach up to 5.0 Gbps when used individually, though actual speeds depend on the connected device. Under sustained load across multiple ports, the shared PCIe x1 lane and controller limit total throughput. The card includes over-current and short-circuit protection on each port for stable operation.

Questions about this item

Does the 5 Gbps figure apply to each port or the whole card?

The 5 Gbps rate is the total bandwidth shared across all five ports; a single port can reach 5 Gbps only when the others are idle.

What PCI Express generation does the x1 slot use?

The card complies with PCIe 2.0 and 3.0 motherboards and operates over a single PCIe 2.0 lane.

Will the card fit in a low-profile bracket?

The board measures 4.92 by 4.06 by 1.06 inches and includes standard-height mounting screws, so it requires a full-height slot.
