Green circuit board with one short PCIe x1 connector and four full-length PCIe x16 slots linked by four blue USB 3.0 cables

SMUGDESK

SMUGDESK PCIe X1 to 4 PCIe X16 USB3.0 Mining Riser Card

SKU CH-1B73-58PD7

A PCIe X1 slot expands to four X16 connectors via USB 3.0 links for multi-GPU mining rigs with tidy wiring

  • One PCIe X1 slot expands to four X16 GPU slots
  • USB 3.0 cabling allows flexible GPU placement in the frame
  • Circuit design tested for 24/7 continuous mining operation
  • Works in X1, X4, X8 or X16 motherboard slots
  • Compatible with Windows and Linux mining operating systems

PCIe X1 to Four X16 Slots

This riser card converts a single PCIe X1 lane into four independent PCIe X16 connectors, letting a mining motherboard host additional graphics cards for BTC mining. It is built for rig builders who need to expand GPU density beyond the native slot count.

USB 3.0 Extension for Frame Layout

The USB 3.0 extension cables allow flexible positioning of each GPU within the mining frame, supporting tidy wiring and reasonable space arrangement. Optimised circuit design targets stable 24/7 operation for continuous cryptocurrency computing tasks.

Sustained 24/7 Mining Operation

The adapter is engineered for long-term constant load rather than short bursts, maintaining signal integrity across all four slots during extended mining sessions. Compatibility with mainstream Windows and Linux mining operating systems ensures consistent software integration.

Questions about this item

How do I install the SMUGDESK PCIe X1 to 4 PCIe X16 riser card, and which step do builders often miss?

Insert the single PCIe X1 connector into any PCIe X1, X4, X8 or X16 motherboard slot, then attach each GPU to the four PCIe X16 slots using the USB3.0 extension cables; the step often missed is connecting auxiliary power to every riser board so all four GPUs receive stable current.

What maintenance or replacement will this mining riser card need during long-term use?

The USB3.0 extension cables and riser PCB sockets endure constant 24/7 operation, so plan to inspect cable connectors for wear and replace any extension cable that shows signal degradation or intermittent GPU detection.

What limit appears first when running four GPUs on this riser continuously?

The single upstream PCIe X1 link caps total bandwidth at one lane, so sustained compute workloads across all four GPUs will hit that bandwidth ceiling before any other constraint.
