4-Port PCIe USB 3.0 Expansion Card

The ESTONE PCIE24ABK adds four USB 3.0 Type-A ports to a desktop computer through a single PCI Express x1 slot. It targets users who need more front-panel connections for peripherals such as keyboards, mice, external drives, webcams, printers, scanners, game controllers, VR headsets and digital cameras.

Driver CD and Smart Power Control

A driver CD is included for Windows XP, Vista, 7, Server 2008 and Linux systems that require manual installation. Windows 10, 11 and Mac OS 10.8.2 or later work without extra drivers. The card draws power directly from the PCIe slot and uses built-in voltage transformers, fuses and solid capacitors to deliver up to 5V/2A per port without an external power cable.

PCIe 2.0 x1 Bandwidth Limit

The adapter complies with the PCI Express 2.0 specification and fits x1, x4, x8 or x16 slots. Total throughput is shared across the four ports and capped at 5 Gbps by the PCIe 2.0 x1 link, so simultaneous high-speed transfers on multiple devices will not reach the nominal USB 3.0 rate for each port. Actual speed also depends on the connected device.

Questions about this item

Will the solid capacitors or fuses on this card need replacement after extended use?

The card uses four solid capacitors and eight fuses for stable power delivery, but no maintenance schedule or user-replaceable parts are specified for these components.

What limits total throughput when all four USB 3.0 ports are active at once?

The PCIe 2.0 x1 link provides a shared 5 Gbps maximum bandwidth across all four ports, so simultaneous transfers are capped by that single-lane connection.

How much heat or power draw should I expect when the card runs continuously with devices attached?

The card draws power from the PCIe slot and supplies up to 5 V/2 A per port, with built-in fuse protection; no active cooling or external power connector is required.
