The PCIe 4.0 x16 GPU Riser Cable from TLD Electronic, a China manufacturer and factory, is built for high-performance internal interconnects in servers, workstations, and custom computing platforms. It addresses the core issue of remotely connecting oversized high-end GPUs or compute accelerators that cannot fit directly into standard motherboard PCIe slots. This solution allows flexible deployment in superior cooling locations or separate expansion bays while ensuring full PCIe 5.0 x16 bandwidth performance.
32 GT/s Transfer Rate: The PCIe 4.0 x16 GPU Riser Cable design and electrical performance meet the PCIe 5.0 specification, with a data transfer rate of 32 Gbps per lane. In a full x16 lane configuration, it provides up to 64 GB/s unidirectional bandwidth (128 GB/s bidirectional), perfectly matching the bandwidth requirements of contemporary high-end graphics cards (such as NVIDIA RTX 40 series, AMD Radeon RX 7000 series, and compute cards).
Backward Compatible: Fully backward compatible with PCIe 4.0 (16 GT/s) and PCIe 3.0 (8 GT/s) standards, allowing connection to older graphics cards or motherboards.
High-Frequency Copper Material: The cable uses high-quality high-frequency copper as the conductor, ensuring extremely low attenuation characteristics under high-frequency signals.
Precise Impedance Control: Differential impedance is precisely controlled at 85 ± 5Ω (strictly following the PCIe specification), effectively reducing signal reflection and ensuring eye diagram opening during long-distance transmission.
Shielding Design: A multi-layer shielding structure (such as aluminum foil Mylar + metal braided mesh) effectively resists complex electromagnetic interference (EMI) inside the chassis, ensuring stable and error-free data transmission.
Standard Slot Specification: Both ends of the cable integrate PCIe x16 male plugs, which can be directly inserted into the motherboard's PCIe x16 slot and the graphics card's gold finger interface. The plug housings usually feature ejectors or retaining clips and provide locking screws to ensure secure connection in high-vibration environments.
Multiple Options and Compactness: For different chassis layouts, straight-exit and 90-degree right-angle exit versions are available; the connector housings are low-profile, facilitating routing in areas dense with heatsinks or cables.
Multiple Custom Lengths: Cable lengths support OEM customization (common range 0.3 m to 1.0 m), allowing flexible selection based on server chassis, mining rig frames, or workstation internal space to avoid cable redundancy or excessive tension.
Compatible Devices: Designed specifically for graphics cards, while also compatible with various PCIe x16 interface accelerator cards (such as AI inference cards, FPGA accelerator cards, and video capture cards).
Latch Structure: Connectors are equipped with a robust locking mechanism to prevent accidental disconnection, ensuring connection reliability in 24/7 uninterrupted operating environments.
Connector Type: Both ends are PCIe x16 male plugs (compliant with PCIe CEM specification)

The PCIe x16 graphics card extension cable is mainly used in the following scenarios:
AI Training and Inference Servers: In 4U or tower servers, multiple GPUs are extended from motherboard slots and arranged on independent air-cooled or liquid-cooled cooling modules, avoiding thermal stacking problems caused by GPU thickness and heat generation.
GPU Cluster Mining Platforms: On open frames, multiple graphics cards are separated from the motherboard to achieve better airflow and cooling efficiency, while also facilitating centralized cable management.
High-Performance Workstations: In compact or irregular chassis (such as vertically mounted motherboards with horizontally placed graphics cards), physical separation of the graphics card from the motherboard is achieved, facilitating display or meeting special industrial design aesthetics.
Edge Computing Devices: In industrial environments with vibration resistance and high temperatures, compute cards are fixed to the chassis structure to enhance reliability, then connected to the core processing board via short-distance cables.
Testing and Development Platforms: When engineers debug motherboards or graphics cards, they lead devices out to a test bench via extension cables, making it easy to connect oscilloscopes, logic analyzers, and other instruments.
RoHS 2.0: Compliant
China RoHS: Yes
REACH SVHC: Yes
