M.2 M Key / PCI-E X1 to 4 PCI-E X16 Mining Expansion Card, 1 to 4 Port PCIe Switch Multiplier Hub with 6Pin SATA Power & USB Riser Cable, Multi-GPU Adapter for BTC ETH Cryptocurrency Mining

This PCIe multiplier expansion card is tailor-made for cryptocurrency mining rigs. It offers two optional input interfaces: M.2 M Key slot and regular PCIe X1 slot, which greatly solves the problem of limited PCIe lanes and insufficient expansion ports on low-cost mining motherboards.

One single input channel can be split into four independent PCI-E X16 output ports. Cooperated with universal PCI-E 1X to 16X riser cards, users can install four graphics cards for hash calculation at the same time to boost overall mining computing power.

Equipped with a dedicated 6Pin SATA power supply interface, it supplements extra electric power for multiple GPUs. It effectively avoids unstable operation, hash rate reduction or sudden shutdown risks caused by insufficient motherboard PCIe slot power output under heavy mining load.

Supporting USB signal transmission connection, the card maintains clean and low-loss PCIe data transmission, reducing signal delay and packet loss during continuous 24-hour mining work. The whole structure adopts reinforced circuit layout with overcurrent protection to extend service life.

Mainly applicable to Bitcoin, Ethereum and other digital currency mining equipment assembly. Compact size saves chassis space, easy to install and wire without complicated driver configuration, an essential expansion accessory for home and small-scale mining rig builders.
