A green circuit board with one PCIe x1 slot and four PCIe x16 slots plus USB 3.0 connectors

SMUGDESK

SMUGDESK PCIe X1 to 4 X16 USB 3.0 Mining Riser Card

SKU CH-HHQ9-WNJMJ

One PCIe X1 slot expands to four PCIe X16 slots via USB 3.0 cables for multi-GPU mining rigs

  • Splits one PCIe X1 slot into four X16 outputs
  • Gold-plated contacts cut signal loss for stable 24-hour mining
  • USB 3.0 cable lets you space cards flexibly inside the frame
  • Works in X1/X4/X8/X16 motherboard slots under Windows or Linux
  • Circuit design built for continuous 24-hour cryptocurrency mining operation

Four GPU expansion from one slot

This PCIe multiplier turns a single X1 motherboard slot into four independent X16 connectors so multiple graphics cards can run in one mining rig. It targets builders who need more GPU density than the board provides without adding extra motherboards or risers. The adapter works with standard Windows and Linux mining operating systems and accepts X1, X4, X8 or X16 slot sizes.

Gold-plated contacts and USB 3.0 links

Gold-plated terminals cut signal loss and keep connections stable during 24-hour continuous mining sessions. Each X16 output connects through a standard USB 3.0 data cable, letting you space cards flexibly inside the rig frame for better airflow or cable routing. The circuit layout is optimised for non-stop cryptocurrency calculation workloads.

Rig-frame mounting implied by flexible cabling

Because the four outputs reach the motherboard via separate USB 3.0 cables, cards can be secured anywhere the frame allows rather than directly over the slot. This removes the clearance limits of rigid risers and suits open-air mining chassis. Builders who need more than four GPUs per board or who require X16 electrical bandwidth per card cannot use this multiplier.

Questions about this item

Will the gold-plated contacts on the PCIe X1 to 4 X16 riser need replacement over time?

The gold-plated terminals are designed to resist oxidation and maintain stable signal quality for long-hour mining sessions, so they do not require scheduled replacement under normal use.

What limits the number of GPUs I can run simultaneously on the four PCIe X16 outputs?

The single PCIe X1 upstream link provides the total bandwidth shared across all four slots, so that upstream width is the first bottleneck when multiple GPUs are active.

How much heat does the multiplier board generate during 24-hour continuous mining?

The board itself draws minimal power and produces little heat; thermal load comes almost entirely from the attached GPUs and the USB 3.0 cables carrying data between them.
