PCIe 1X Extension Cable with IC Radiator and 4 Slot Extendability Key benefits Easy installation: a single locking cable provides secure and straightforward setup without special tools. Efficient heat management: built in IC radiator helps dissipate heat for stable operation. Flexible expandability: 4 slot configuration allows expanded PCIe 1X connectivity for add on cards or devices. Durable wiring: designed for precise fit and reliable connections. Compatibility and requirements Compatible with motherboard PCIe 1X slots. Requires the floppy power connector to supply power to the extension. After installing the PCIe extension, reconnect the PC power wires as required. Important usage notes The wire set is custom shaped; never force a plug into a socket. The wiring has a defined orientation; do not insert reversed or offset connections to avoid damage. When connecting, plug into the device socket first, then connect to the motherboard socket to prevent excessive pin force and possible damage. What you receive PCIe 1X extension cable with IC radiator and 4 slot extendability Wire set designed for reliable connections and secure fit Locking cable assembly for easy, stable installation Use scenarios Upgrading an older desktop with PCIe 1X slots to add network, sound, or USB expansion cards while maintaining good thermal performance. Building a compact or space constrained system where routing PCIe 1X extensions with integrated cooling helps manage heat and airflow. Server or workstation maintenance requiring additional PCIe 1X expansion with improved heat dissipation and organized cable management.
