PCIe 3.0 x16 Male to x1 Female Up R/A Extension Cable

The PCIe 3.0 x16 Male to x1 Female Up R/A Extension Cable is a specialized passive interconnect solution engineered for space-constrained systems requiring adaptive connectivity between different PCIe slot sizes while maintaining PCIe 3.0 compliance. This cable converts a larger PCIe x16 slot interface into a smaller PCIe x1 interface, supporting a data transfer rate of 8.0 GT/s per lane and delivering a bandwidth of approximately 985 MB/s for the x1 interface, with backward compatibility to PCIe 2.0/1.0 devices . The design incorporates an Up Right-Angle (Up R/A) female connector that optimizes vertical clearance by directing the cable upward relative to the motherboard plane, reducing mechanical obstruction in dense configurations such as compact workstations or servers requiring vertical GPU installation . Constructed with impedance-controlled wiring (targeting 85-ohm differential) and multi-layer shielding (e.g., foil and braid as used in industry designs ), this cable minimizes signal degradation while addressing mechanical routing challenges. The passive design addresses both form-factor adaptation and cable routing needs, making it ideal for test benches, custom PCs, and specialized computing setups where flexible card placement is critical.

Features

• Form Factor Adaptation: Enables physical and electrical compatibility between PCIe x16 and x1 interfaces, allowing x1 devices (e.g., NICs or capture cards) to be installed in x16 slots while operating at x1 lane speeds .
• Up Right-Angle Connector Optimization: The Up R/A female connector (as defined in  interface terminology ) directs the cable upward relative to the motherboard plane, minimizing interference with adjacent components and improving airflow management in cramped enclosures .
• PCIe 3.0 Compliance: Supports PCIe 3.0 specifications with a data transfer rate of 8.0 GT/s per lane, providing approximately 985 MB/s bandwidth for the x1 interface .
• Enhanced Signal Integrity: Utilizes multi-layer shielding (e.g., EMI protection as referenced in ROG Strix Riser Cable ) to minimize insertion loss, crosstalk, and electromagnetic interference (EMI), ensuring stable performance in high-frequency environments .
• Passive Design: Requires no external power or active components, relying on high-quality copper conductors (e.g., imported copper wire as seen in industry designs ) and precise impedance control for reliable operation .
• Durable Construction: Incorporates robust materials such as reinforced connector housings and strain relief (e.g., similar to TT Premium's design ) to withstand mechanical stress in commercial or development environments.
