PCIe 4.0 x16 Male to x16 Female Down R/A Extension Cable

The PCIe 4.0 x16 Male to x16 Female Down R/A Extension Cable is a high-performance interconnect solution engineered for space-constrained computing systems . This cable features a Down Right-Angle (Down R/A) female connector that directs the extension downward relative to the motherboard plane, optimizing space utilization in dense server racks and compact chassis . Supporting the complete PCIe 4.0 specification with full x16 lane preservation, it delivers a maximum theoretical bandwidth of up to 16 GT/s per lane while maintaining superior signal integrity through precision impedance control . The robust construction ensures reliable performance in demanding environments, making it ideal for high-density configurations where both form factor and data integrity are critical .
