One PCI-E 4X slot expands to four USB 3.0 ports

This riser card turns a single PCI-E 4X slot into four external USB 3.0 connectors. It plugs directly into a 4X, 8X or 16X motherboard slot and needs no extra power cable. The board is aimed at mining rigs or multi-GPU setups that have run out of native PCI-E lanes. It will not fit a PCI-E X1 slot.

Four ports share one 4X lane for mining cards

Each USB 3.0 port carries a PCI-E signal to a riser board or GPU adapter. Bandwidth is limited to the host slot’s 4X width, so four active devices divide that throughput. The design works for cryptocurrency mining where each card runs at reduced speed. It is not suited for workloads that need full 16X bandwidth per device.

Gold-plated USB connectors cut interference

The four USB 3.0 sockets are gold-plated to lower contact resistance and signal noise. No external power adapter is required because the card draws power from the PCI-E slot itself. The direct-mount layout removes ribbon cables, reducing clutter and potential failure points. Buyers who need shielded cables or powered risers must source them separately.

Questions about this item

Will the PCI-E 4X riser card work in my older motherboard that only has a PCI-E 16X slot?

Yes, the bus interface is compatible with 4X, 8X and 16X graphics card slots, so it will fit your existing 16X slot.

How can I confirm the four USB 3.0 ports are delivering full speed after installation?

Check Device Manager or lsusb -t on Linux; each port should enumerate as a 5 Gbps SuperSpeed link with no errors reported.

Does the package include the four USB 3.0 cables needed to connect my GPUs, or must I buy them separately?

The box contains only the riser card itself; four USB 3.0 cables for the GPU connections are not included and must be purchased separately.
