Expand to 2 Interfaces: The PCI E 1X to 2 PCI E multiplier card effectively solves the problem of insufficient PCI E interfaces on the motherboard by expanding 1 interface into 2. Direct Power Supply: The main control board uses the PCI E interface for direct power supply, eliminating the need for an external power cable. The two PCI E interfaces are gold-plated, and the main control board is protected from external interference. Stable Transmission: The PCI E riser card utilizes the ASMedia ASM1182E main controller, ensuring high-speed and stable transmission. Broad Compatibility: The PCI E expansion card is compatible with PCI E 4X, 8X, and 16X. The system supports DOS, Linux, Win7, Win8, Win10, Win11, and other systems. Easy Installation: Before installation, the motherboard must be powered off. Then, align the card slot to effectively reduce interface interference, ensure data reliability, and improve work efficiency.
