PCIe 4.0 x4 Male to x16 Female Down R/A Extension Cable, 85-ohm Low Impedance

The PCIe 4.0 x4 Male to x16 Female Down R/A Extension Cable is a high-performance interconnect solution designed for professional computing environments requiring reliable PCIe signal extension with specific mechanical orientation. This cable features a standard x4 male connector that interfaces with the motherboard slot, extending to an x16 female connector in a Down Right-Angle configuration. The down-angled design facilitates optimal cable routing in space-constrained chassis and server racks where clearance above the connector is limited. Engineered with precise 85-ohm low impedance characteristics, this cable maintains superior signal integrity at PCIe 4.0 data rates, making it ideal for extending graphics cards, storage controllers, and other PCIe 4.0 adapters in demanding applications.
