M.2 M Key to 4 PCIe X16 Mining Multiplier HUB, 1 to 4 Port PCI Express Switch Riser Card with 6Pin SATA & USB Power Interface, Multi-GPU Expansion Adapter for BTC ETH Ethereum Mining Rig

This PCIe multiplier hub converts a single M.2 M Key NVME slot or PCI-E X1 slot into four full PCIe X16 expansion slots, perfectly solving the problem of insufficient motherboard PCIe slots for multi-GPU mining rigs. Equipped with dual power supply ports (6Pin SATA + USB power) to supply stable power to each connected graphics card, avoiding insufficient power failure during high-load mining. It adopts multi-layer anti-interference PCB and independent cooling heatsink to guarantee stable signal transmission under 24/7 continuous running. The matched high-speed shielded USB3.0 connecting cable supports flexible layout inside mining chassis, compatible with all mainstream AMD and NVIDIA mining GPUs. No driver installation required, supports all common mining operating systems, a necessary expansion adapter for building 4-GPU crypto mining rigs.
