1. This PCI-E to USB adapter board is designed with 4 USB ports supporting USB 3.0, which can provide fast data transmission. PCI-E1X can be expanded to 16X. The newly launched circuit board PCIe adapter cable is , more efficient and more practical! The 2.4 port PCI-E to USB 3.0 adopts the PCI-E X1 bus interface design and is powered by the PCI-E interface, so the power supply is stable and reliable. The graphics card power supply uses 8 solid capacitors to make the graphics card power supply more stable and safe. 3. The 6PIN interface of the adapter card enhances the power supply, making it more powerful and flexible. The SATA port is converted to a 6PIN line, so the power of the graphics card is of the motherboard, thus reducing the burden on the motherboard when connecting multiple graphics cards. 4. PCI-E devices can be flexibly placed using a 60 cm USB 3.0 data cable. The PCI-E connector uses a multi-layer shielded cable and can be connected to 3 Meter without signal attenuation. 5. The PCI-E to USB adapter has 4 USB ports, allowing you to PCI-E adapter boards, enhanced PCI-E 1X slot, with better connectivity and longer service life. Specially used for mining by miners.
