Pci-e 4x 1 to 4 Ports Usb 3.0 Pci-e Adapter for Btc Bitcoin Miner

1. The bus interface is PCI-E X4, the bus speed can be up to 20Gbps, compatible with X4, X8, X16 graphics interfaces, 1 interface can be expanded to 4 USB3.0 interfaces, effectively solving the problem of insufficient PCIe interface on the motherboard. Note: Adapter cards cannot be connected to USB devices because the 4 USB ports carry PCI-E signals, not USB signals.2. The oversized metal heat sink effectively dissipates excess heat, so that the riser card is always at a normal temperature and operates more stably.3. The PCI-E adapter card adopts a plug-in design and is directly connected to the motherboard interface for power supply. It can be fixed on the chassis without extension cables, reducing the number of adapters and jumpers, effectively reducing interface interference and line loss, ensuring data reliability and stability, and improving work efficiency.4. Strong stability, the main control board uses the PCI-E interface to directly supply power, no external power cord is required, so that the main control board is free from external interference. 4 USB 3.0 ports work at the same time, backward compatible with USB 2.0 and USB 1.0, with higher stability.5. Wide compatibility, all interfaces support PCIE X1/X4/X8/X16 graphics card interface. The interface supports USB3.0 and is backward compatible with USB 2.0/1.0.
