PCIe 4.0 x1 Male to x8 Female Up R/A Extension Cable, 85-ohm Low Impedance

The PCIe 4.0 x1 Male to x8 Female Up R/A Extension Cable is a high-performance interface extension solution designed to connect PCIe 4.0 x1 host interfaces to PCIe x8 devices using an upward right-angle (Up R/A) female connector. This cable features a PCIe 4.0 x1 male connector on one end and an upward right-angle PCIe x8 female connector on the other end, enabling seamless integration of x8 devices (e.g., expansion cards, NICs) 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, as seen in premium designs like 3M™ Twin Axial Cable) 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 optimal airflow management and cable routing in dense configurations.

Compatibility Notes

This cable is designed for connecting PCIe x8 devices to PCIe 4.0 x1 host interfaces. The upward right-angle x8 connector is ideal for environments where vertical space is limited and cable routing must avoid obstruction (e.g., above PCB trays). 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).
