Adds five USB 3.0 ports through one PCIe x1 slot with no extra power cable required
This PCIe x1 add-in card multiplies a single lane into five USB 3.0 ports. It targets miners and builders who need many risers or peripherals from one motherboard slot. The board draws power directly from the PCIe slot, so no external cable is required. Supported operating systems include Windows 7 through 11, Linux and DOS.
Each port runs at USB 3.0 signalling rates, and the onboard controller maintains bandwidth when all five links are active. The integrated IC heatsink dissipates heat during continuous mining or bulk-transfer workloads. Because the card uses only slot power, the motherboard supply remains isolated from external fluctuations. Stability is preserved over long sessions without thermal throttling.
The card plugs straight into a PCIe x1, x4, x8 or x16 slot and can be screwed to the chassis. A single floppy-style power connector must be attached before the system is powered on. The custom wiring harness is keyed; reversing or forcing it can burn components. Identify the connector direction, seat the card firmly, then attach the power lead.
