PCIe X4 to 4 PCIe Slot Multiplier Riser Card, 4-Port USB 3.0 PCI-E Signal Splitter Expansion Adapter for GPU Bitcoin Crypto Mining Rig

This PCIe X4 to 4-port PCIe multiplier riser card is a dedicated expansion accessory for Bitcoin, Ethereum and other cryptocurrency mining rigs. It converts one motherboard PCIe X4 slot into four PCIe signal transmission ports via USB 3.0 interfaces, allowing you to connect four GPU PCIe risers simultaneously and greatly expand the number of graphics cards your mining host can carry.

Equipped with a thick aluminum heat sink on the main control chip, this card delivers excellent thermal performance to avoid overheating failures during 24/7 continuous mining. All USB connectors adopt gold-plated contacts to lower signal attenuation and anti-interference ability, eliminating frequent GPU drop-off, unrecognition and hash rate loss caused by poor signal transmission.

Note: The four USB 3.0 ports output pure PCIe signals only and cannot be used for regular USB peripherals like flash drives or keyboards. It is backward compatible with PCIe X8 and X16 motherboard slots, fitting ATX mining motherboards from mainstream brands. Installation is straightforward without complicated driver setup, compatible with Windows 7/10/11 and all mainstream Linux mining systems.

It effectively reduces the quantity of host motherboards required for large-scale mining farms, optimizes rig layout and improves internal airflow. Ideal for home small mining rigs and commercial large crypto mining workstation upgrades.
