1. Great Flexibility: PCI E 1X to 2 PCI E multiplier card, 1 interface can be expanded to 2 PCI E interfaces, effectively solving the problem of insufficient PCI E interfaces on the motherboard. 2. High Stability: The PCI E 1 to 2 riser card uses the PCI E interface to directly deliver power, no external power cable is required, and the main control board is free from external interference and has strong stability. 3. Powerful Chip: The PCIe splitter 1 to 2 PCIE riser card uses the ASMedia ASM1182E main control for high-speed and stable transmission. 4. Wide Compatibility: The PCI E 1X to external 2 PCI E USB 3.0 adapter is compatible with PCI E 4X, 8X, 16X; the system supports Linux, Win7, Win8, Win10, Win11, and other systems. 5. Easy Installation: Before installation, the motherboard must be turned off, then align the slot position, which can effectively reduce interface interference, ensure data reliability, and improve work efficiency.
