SMUGDESK PCIe 4X to 4×USB 3.0 Multiplier Riser Card
Expands one PCIe 4X slot into four USB 3.0 ports for connecting multiple GPU risers in mining rigs
- One PCIe 4X slot expands to four USB 3.0 ports for multi-GPU mining rigs
- Dedicated multiplier control chip maintains stable signal transmission during 24-hour continuous operation
- USB wired connections improve internal chassis layout and heat dissipation for mining equipment
- Standard metal mounting bracket fits mainstream mining motherboards and PCIe X4/X8/X16 slots
- Works with Windows and Linux mining operating systems after simple driver installation
Multi-GPU Mining Expansion
This PCIe 4X multiplier card splits a single slot into four USB 3.0 signal ports, letting builders attach four PCIe 16X GPU risers for a dense mining rig. It is designed for operators who need more GPU positions than the motherboard provides and want a cost-effective way to scale hash rate. A dedicated control chip keeps signals stable during 24-hour continuous operation.
Builders with limited slots; not for general I/O
The card suits miners running Windows or Linux mining OSes on boards with spare PCIe X4, X8 or X16 slots and a standard metal bracket mounting point. It is not for users who need extra USB ports for peripherals, storage drives or other non-GPU devices, nor for systems that lack the physical space or power delivery for four additional graphics cards.
One PCIe 4X to four USB 3.0 ports
The single specification that decides fit is the 1-to-4 lane split: one PCIe 4X input becomes four USB 3.0 outputs wired for PCIe 16X risers. If the motherboard cannot spare a compatible PCIe slot or the chassis cannot accommodate four riser cables and GPUs, this adapter will not solve the expansion problem.

Questions about this item
Does the card ship with the four USB 3.0 riser cables or do they need to be bought separately?
The package contains only the multiplier card and its metal mounting bracket; four PCIe 16X riser cables must be purchased separately.
Which PCIe slot widths on my motherboard will accept this multiplier card?
The standard bracket fits PCIe X4, X8 and X16 slots, so any of those widths will work.
What does the 1-to-4 expansion mean for GPU density inside a single chassis?
One PCIe 4X lane is divided into four USB 3.0 signal ports, letting you install four graphics cards where only one slot was available.
