Product identity

The ESTONE PCIE24ABK adds four USB 3.0 Type-A ports to a desktop computer through a PCI Express x1 slot. It is aimed at users who need more SuperSpeed connections for external drives, VR sensors, webcams or other peripherals without fitting an extra power cable.

Installation and common issues

Shut down the PC, unplug the mains, open the case and seat the card in any x1, x4, x8 or x16 socket before securing the bracket screw. Windows 10, 11 and Mac OS 10.8.2 or later load the driver automatically; Windows 7, 8, Vista, XP and Server 2008 require the supplied CD or a downloaded driver. The card draws all power from the slot, so no auxiliary connector is needed.

Practical limits of the interface

The PCIe 2.0 x1 link caps total throughput at 5.0 Gbps shared across the four ports, so simultaneous transfers from multiple high-speed drives will not reach the per-port maximum. Each port can supply up to 5 V at 3 A, yet the specification notes that Battery Charging 1.2 is not supported, so phones or tablets may charge more slowly than with a dedicated charger.

Questions about this item

How can I verify the card is running at 5.0 Gbps after installing it?

Open Device Manager, expand Universal Serial Bus controllers, confirm the controller shows USB 3.0 and the port speed reads 5.0 Gbps, then copy a large file to a USB 3.0 drive and check that the transfer rate approaches the rated speed.

What comes in the package and what must I source separately?

The box contains the PCIe USB 3.0 card, a driver CD, mounting screws and a user manual; no extra power cable is required because the card draws up to 5V/3000mA from the slot.

Which PCI Express slot should I use for this x1 card?

The card fits any PCIe x1, x4, x8 or x16 socket and is compliant with PCI Express 2.0, so choose any free slot that matches your motherboard layout.
