SMUGDESK

SMUGDESK PCIe 1x to 16x Riser Card 1-to-2 USB 3.0 Multiplier Hub Data Adapter

SKU CH-KHPX-8TDR1

Converts one PCIe x1 slot into two x16 slots using shielded USB 3.0 links for mining rigs

  • Doubles GPU capacity by splitting one PCIe x1 slot into two x16 slots
  • Stable high-speed data via shielded USB 3.0 cable between interfaces
  • Powers both slots directly from PCIe bus with gold-plated contacts
  • Plug-and-play installation fits open-air mining frames without extra cables
  • Runs Windows, Linux and DOS with mainstream BTC/ETH mining software

Dual GPU Expansion

This PCIe 1x to 16x riser card converts a single motherboard x1 slot into two independent x16 slots. It uses a shielded USB 3.0 cable for data transmission between the interfaces. The adapter is powered directly from the PCIe slot without an external PSU connection. It targets cryptocurrency mining rigs that need to scale GPU density on open-air frames.

Mining Rigs Only

Builders expanding a Bitcoin or Ethereum mining operation will find the 1-to-2 multiplier useful for adding a second GPU per slot. The plug-and-play design suits Windows, Linux and DOS environments running mainstream mining software. Gamers or workstation users needing full x16 bandwidth per card should look elsewhere, as the x1 host link limits throughput. Anyone requiring auxiliary power connectors for high-TDP cards cannot use this unit.

No Extra Cables Needed

The bundle relies on the motherboard slot for all power delivery, so no separate PSU cables are included or required. Gold-plated contacts on the x16 slots aim to maintain reliable connectivity over extended mining sessions. The USB 3.0 link cable is the only data path provided; no additional adapters, drivers or configuration utilities ship with the product.

Questions about this item

What motherboard slot is required for the PCIe x1 to x16 riser card?

The adapter plugs into a single PCIe x1 slot on the motherboard to provide two x16 connections.

Will the USB 3.0 link work with GPUs installed in the two multiplied x16 slots?

Yes, the shielded USB 3.0 cable carries data between the x1 host slot and each x16 GPU slot for mining workloads.

How can I confirm both multiplied x16 slots are active after plugging in two GPUs?

Both GPUs should appear in the OS device manager or mining software, showing two separate devices on one x1 root port.
