Welcome to the store! 1. Expands to 2 Interfaces: The PCI E 1X to 2 PCI E multiplier card allows one interface to be expanded into two PCI E interfaces, effectively solving the problem of insufficient PCI E interfaces on the motherboard. 2. Direct Power Supply: The main control board uses the PCI E interface for direct power supply, eliminating the need for external power. Both PCI E interfaces are gold-plated, and the main control board is not subject to external interference. 3. Stable Transmission: The PCI E riser card utilizes the ASMedia ASM1182E master controller, ensuring high-speed and stable data transmission. 4. Wide 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 operating systems. 5.
