SMUGDESK

SMUGDESK 5-Port USB3.2 Gen2 10Gbps PCIe X4 USB Converter

SKU CH-YQ0A-HCZTE

Adds five 10 Gbps USB ports via a PCIe x4 slot for fast external drives and peripherals

  • Five ports deliver 10 Gbps each via PCIe X4 bandwidth
  • UASP acceleration and per-port protection prevent drop-outs under full load
  • Fits X4, X8 or X16 slots on Intel and AMD motherboards
  • Standard full-height bracket works in ATX, mATX and ITX cases
  • Plug-and-play on Windows 11/10/8/7 and mainstream Linux systems

PCIe X4 10Gbps expansion card

This PCIe X4 expansion card adds five USB3.2 Gen2 ports to a desktop computer. Each port delivers up to 10Gbps bandwidth for external SSD enclosures and large file backup. The design suits DIY PC assembly, content creation workstations and NAS upgrades.

Bus-powered with protection circuits

The card draws power directly from the PCIe slot so no external power cable is required. A dedicated controller chip provides UASP acceleration and independent overcurrent and ESD protection circuits to prevent device drop-out under full load.

Standard bracket fits ATX ITX mATX

A full-height metal bracket allows installation in ATX, mATX and ITX chassis. The card is compatible with Intel and AMD motherboards using PCIe X4, X8 or X16 slots. Plug-and-play support covers Windows 11, 10, 8, 7 and mainstream Linux systems.

Questions about this item

How do I install this PCIe X4 card and which step causes the most issues?

Insert the card into any PCIe X4, X8 or X16 slot, secure the full-height metal bracket to the chassis, and connect the internal USB header cable to the motherboard header — missing that header connection is the step that leaves ports dead.

What maintenance or replacement will this 5-port expansion card need later?

The on-board overcurrent and ESD protection circuits are non-replaceable; if a port fails under full-load use the whole card must be swapped, and dust should be cleared from the bracket vents periodically.

What limit appears first when all five ports run sustained 10Gbps transfers?

The PCIe X4 bus caps total throughput at the Gen2 lane rate, so aggregate bandwidth across all ports hits that ceiling before any single port reaches its 10Gbps maximum.
