Green printed circuit board with a gold PCIe x1 edge connector and five blue USB 3.0 ports along the edge

SMUGDESK

SMUGDESK PCIe X1 to 5-Port USB 3.0 Multiplier Riser Card

SKU CH-FMHZ-76Y2M

Converts a single PCIe X1 slot into five USB 3.0 ports for stable multi-GPU mining rig expansion

  • Single PCIe X1 slot becomes five USB 3.0 ports for multi-GPU mining rigs
  • Upgraded circuit layout cuts signal interference and device dropouts under heavy load
  • Standard PCIe X1 form factor fits ATX boards and open-air mining frames
  • Works with Windows, Linux and Mac OS for broad system compatibility
  • Plug-and-play design needs no extra drivers for fast rig assembly

Single PCIe X1 to five USB 3.0 ports

This adapter converts one motherboard PCIe X1 slot into five independent USB 3.0 ports for connecting multiple GPU riser cables. It targets builders assembling cryptocurrency mining rigs who need to maximise slot utilisation on a single board. The card suits DIY home mining setups and small farm deployments running Windows, Linux or Mac OS.

PCIe X1 bandwidth shared across five ports

All five USB 3.0 interfaces share the throughput of a single PCIe X1 lane, so aggregate data rate is limited by that upstream connection. Continuous high-load mining traffic on several GPUs simultaneously may saturate the link and cause contention. The design focuses on signal stability rather than multiplying raw bandwidth.

Five USB 3.0 ports from one PCIe X1 slot

The decisive specification is the 1-to-5 port expansion ratio, which determines how many riser cables can attach to a single motherboard slot. Buyers who need more than five connections per slot or who require dedicated bandwidth per GPU will find this multiplier insufficient.

Questions about this item

How many USB 3.0 ports does the PCIe X1 to 5-Port multiplier provide?

The card converts a single PCIe X1 slot into five independent USB 3.0 ports for connecting multiple GPU riser cables.

Will the five USB 3.0 ports maintain stable connections during continuous mining loads?

An upgraded circuit layout reduces signal interference and unexpected device dropout under sustained high-load operation.

Does the PCIe X1 interface limit the bandwidth available to each USB 3.0 port?

The single PCIe X1 lane shares its throughput across all five ports, so simultaneous high-speed transfers will be constrained by that link.
