4slot PCIe 1X extension for greater extendability Singlecable installation for simple setup A compact design uses one cable to connect to the motherboard, enabling quick installation and reducing cable clutter. Compatibility and power Designed for PCIe 1X slots on motherboards. This extension provides a PCIe slot power solution and does not require an extra power cable. Safe handling and installation notes The wire harness is customshaped to ensure proper alignment and to prevent wrong connections. When wiring, identify the correct orientation and avoid reversing or offsetting connections to prevent damage. Plug the motherboard socket first, then attach the extension cable. Do not apply excessive force to connectors or pins. Important usage guidance If your system requires it, reconnect any required power wiring after installing the extension. Ensure all connections are secure before use, and verify that no pins are bent or stressed. Applications and use scenarios Desktops or small servers with limited PCIe 1X slots: add multiple PCIe devices (network cards, USB expansion, capture cards, etc.) without needing additional power cables. Test benches or development workstations: quickly swap PCIe devices for testing and validation. Compact builds where maximizing PCIe expansion from a single 1X slot is desirable, without introducing extra power cabling.
