Product Introduction: AI Server GPU Riser – PCIe 4.0 x8 to x16 Extension Cable

Unlock flexible and high-performance GPU deployment in dense AI server and computing racks with our dedicated PCIe 4.0 GPU Riser Cable. This specialized extension cable is engineered to overcome physical space constraints by allowing a critical PCIe x8 signal from the server motherboard to be efficiently adapted and extended to a full-length PCIe x16 slot, perfectly accommodating modern double-wide GPUs and accelerators.

Key Features & Benefits:

• AI & HPC Server Optimized: Specifically designed for the rigorous demands of AI training, inference, and high-performance computing servers where optimal GPU placement and cooling are paramount.

• PCIe 4.0 High-Speed Signal Integrity: Built with precise impedance control and premium shielding to maintain signal integrity at up to 16 GT/s data rates, ensuring minimal performance loss for data-intensive GPU workloads.

• x8 to x16 Smart Adaptation: Intelligently routes the available PCIe x8 lanes from your host to the standard x16 connector on the GPU. This provides full mechanical compatibility and electrical functionality for GPUs that do not require a full x16 electrical link (common in many multi-GPU configurations).

• Enhanced System Design Flexibility: Enables horizontal, vertical, or offset GPU mounting. This is crucial for improving airflow in 1U/2U servers, building custom GPU clusters, or fitting accelerators into space-limited chassis.

• Robust & Reliable Construction: Features industrial-grade, low-loss coaxial cables, gold-plated contacts, and sturdy metal brackets to ensure secure mounting and long-term reliability in 24/7 operating environments.

Primary Applications:

• Dense AI Server Racks: Installing multiple GPUs (NVIDIA H100/A100, RTX 4090, etc.) in standardized server chassis.

• Custom Computing Nodes: Building specialized workstations or compute nodes for deep learning and scientific research.

• Cryptocurrency Mining Rigs: (Where applicable) Organizing and spacing out GPUs for improved thermal management.

• High-Density Storage or Accelerator Arrays: Connecting other PCIe 4.0-based accelerators or storage cards.

Typical Specifications:

• Interface Standard: PCI Express 4.0

• Host Side Connector: PCIe x8 Plug (for motherboard or backplane)

• Device Side Connector: PCIe x16 Socket (for GPU/Accelerator)

• Cable Length: Common options from 15cm to 50cm

• Key Consideration: Performance is ultimately constrained by the host's available PCIe lanes (x8). Ensure your system's PCIe slot configuration and airflow design align with this solution.
