SMUGDESK
SMUGDESK PCIe 1 to 4 USB3.0 Port Multiplier Expansion Adapter
A PCIe 1-to-4 port multiplier using USB 3.0 extends one motherboard slot into four interfaces for multi-GPU mining rigs and desktop PCIe expansion
- Expands one PCIe slot into four ports
- PCIe switch chip with solid capacitors protects against surges
- Fits X1, X4, X8 and X16 motherboard slots
- Runs on Windows 11, 10, 8, 7, Linux, HiveOS, RaveOS
- Heatsink keeps chip cool during continuous mining
Expansion Capability
This PCIe 1-to-4 multiplier uses USB3.0 signal transmission to turn a single motherboard PCIe X1 slot into four independent PCIe X1 ports, allowing up to four graphics cards to be mounted via standard risers for multi-GPU computing or mining rigs.
Target Builders
It suits builders who need cost-effective PCIe lane expansion on boards with limited slots and who run Windows 11, 10, 8, 7, Linux, HiveOS or RaveOS; it is not for systems that require native PCIe bandwidth per device or that cannot accommodate USB3.0 cable routing.
Key Specification
The adapter employs a professional PCIe switch controller with solid-capacitor power circuitry and an integrated heatsink to deliver stable signal output with anti-surge and overcurrent protection during continuous operation.
Highlights
- Expands one PCIe slot into four ports
- PCIe switch chip with solid capacitors protects against surges
- Fits X1, X4, X8 and X16 motherboard slots
- Runs on Windows 11, 10, 8, 7, Linux, HiveOS, RaveOS
- Heatsink keeps chip cool during continuous mining

Questions about this item
How do I verify the four PCIe slots are active after installing the SMUGDESK multiplier card?
Boot the mining OS — Windows 11, 10, 8, 7, Linux, HiveOS or RaveOS — and confirm each GPU appears in device manager or the mining dashboard with a stable hash rate.
What ships with the card and what must I source separately?
The box contains the PCIe 1-to-4 multiplier board with integrated heatsink and a USB 3.0 data cable; you still need four PCIe 1X-to-16X risers and the GPUs themselves.
Which version of this multiplier should I choose for a four-GPU mining rig?
This single model turns one PCIe X1, X4, X8 or X16 slot into four independent PCIe X1 ports, so one unit covers a four-GPU build.
