PCIe 4.0 x1 Male Up R/A to x4 Female Down R/A Extension Cable

The PCIe 4.0 x1 Male Up R/A to x4 Female Down R/A Extension Cable is a high-performance, dual-orientation interface extension solution designed to connect PCIe 4.0 x1 host interfaces to PCIe x4 devices. This cable features an upward right-angle (Up R/A) PCIe 4.0 x1 male connector on one end and a downward right-angle (Down R/A) PCIe x4 female connector on the other end. Engineered for complex routing scenarios in space-constrained environments, it utilizes 85? low-impedance twin-axial cable technology (e.g., 31 AWG signal wires, as utilized in premium 3M™ designs) to minimize signal degradation and ensure high-speed data transfer. It is ideal for server upgrades, compact workstations, high-density data centers, and applications requiring flexible PCIe expansion with optimized airflow management and intricate cable routing.

Compatibility Notes

This cable is designed for connecting PCIe x4 devices to PCIe 4.0 x1 host interfaces. The upward right-angle x1 male connector is typically inserted into the motherboard slot, while the downward right-angle x4 female connector receives the expansion card. Ensure the host system’s PCIe slot supports PCIe 4.0 or earlier versions (3.0/2.0) for backward compatibility. For best performance, connect the cable to the motherboard's primary PCIe x16 slot (usually closest to the CPU).
