PCIe 4.0 x1 Male to x16 Female Extension Cable with Lock
The PCIe 4.0 x1 Male to x16 Female Extension Cable with Lock is a high-performance interface extension solution designed to connect PCIe 4.0 x1 host interfaces to PCIe x16 devices. This cable features a PCIe 4.0 x1 male connector on one end and a PCIe x16 female connector with a locking mechanism on the other end, enabling secure integration of x16 devices (e.g., GPUs, expansion cards) into systems with limited PCIe slot availability or space constraints. Engineered for reliability and signal integrity, this cable utilizes 85? low-impedance twin-axial cable technology (e.g., 31 AWG signal wires) to minimize signal degradation and ensure high-speed data transfer. It is ideal for gaming rigs, compact workstations, server upgrades, and applications requiring flexible PCIe expansion with secure connections and optimal airflow management.

Compatibility Notes
This cable is designed for connecting PCIe x16 devices to PCIe 4.0 x1 host interfaces. The locking mechanism ensures secure connections in high-vibration environments. Ensure the host system’s PCIe slot supports PCIe 4.0 or earlier versions (3.0/2.0) for backward compatibility. Note that while the cable provides mechanical x16 compatibility, the electrical bandwidth is limited to PCIe x1 (e.g., PCIe 4.0 x1 theoretical bandwidth is ~2 GB/s, while a native x16 slot can reach ~32 GB/s). Verify device power requirements, as some x16 devices (e.g., high-end GPUs) may require additional power connectors not provided by the cable. This solution is not suitable for devices requiring full x16 electrical bandwidth for optimal performance.
Note: All specifications adhere to PCI-SIG PCIe 4.0 standards and low-impedance design principles (85?), ensuring interoperability with PCIe-based systems. For optimal performance, use high-quality cables with proper shielding to minimize signal degradation. The locking mechanism enhances reliability in environments where vibration or movement may occur.
