SMUGDESK 4-Port PCIe USB 3.0 Expansion Card

SKU CH-S5XY-1VKFB

  • Adds four USB 3.0 ports via one PCIe X1 slot
  • Each port delivers up to 5 Gbps, ten times USB 2.0 speed
  • Built-in overcurrent protection with optional 4-pin power for demanding devices
  • Works with Windows 11, 10, 8, 7, XP and Linux; auto driver on Win 10/11
  • Low-profile bracket fits standard PCs, NAS units and industrial hosts

Four USB 3.0 ports from one PCIe slot

The SMUGDESK expansion card plugs into a single PCIe X1 slot and adds four independent USB 3.0 Type-A ports to a desktop or small-form-factor system. Each port delivers up to 5 Gbps bandwidth and remains backward compatible with USB 2.0 and 1.1 peripherals. An optional 4-pin IDE power connector supplies extra current for high-draw devices such as external SSDs or industrial cameras.

Desktop builders and industrial integrators

The card suits anyone whose motherboard lacks enough USB 3.0 ports for storage arrays, capture gear or legacy accessories. It supports Windows 11 down to XP plus mainstream Linux distributions, with automatic driver installation on Windows 10 and 11. Builders who require internal USB-C headers or more than four added ports will need a different solution.

Single PCIe X1 lane interface

The adapter operates over one PCIe lane, so it fits X1, X4, X8 or X16 slots without configuration. This lane width determines the total throughput shared across the four ports and is the key specification to verify against the host platform.

Questions about this item

Does the SMUGDESK 4-Port PCIe USB 3.0 Expansion Card generate much heat or noise when running all day?

The card is a passive expansion board with no fan, so it produces no audible noise and minimal heat during continuous operation.

What must I already own for the SMUGDESK 4-Port PCIe USB 3.0 Expansion Card to work?

You need a desktop motherboard with a free PCIe X1, X4, X8 or X16 slot and an available 4-pin IDE power connector if you plan to attach high-power devices.

Will the SMUGDESK 4-Port PCIe USB 3.0 Expansion Card work alongside my older USB 2.0 and 1.1 peripherals?

Yes, each port is backward compatible with USB 2.0 and 1.1 devices, so legacy keyboards, mice and printers will function normally.
