PCIe 4.0 x4 to x16 Riser Cable, Speed Flexible GPU Extension for Small Form Factor PC 5cm

Product name: PCIe x4 to x16 extension cable Models: M2SM31,M2SM32,M2SM33 Size: 5cm Color: M2SM33TL Transfer speed: PCIe 4.0 x4, 64 Gbps (Max.) Wire length: 3 to 40 cm, Key benefits Flexible placement of expansion cards and GPUs by converting a motherboard PCIe x4 interface to a x16 connector, enabling layouts that standard cables or fixed slots cannot. Preserves PCIe 4.0 x4 bandwidth up to 64 Gbps for throughput tasks, reducing the risk of bottlenecks when relocating cards. cable length from 3 to 40 cm accommodates tight cases, test benches, and modular rigs while minimizing excess cable and improving airflow. Compact footprint with a 5 cm option for installations where space is limited. Color option M2SM33TL and multiple models allow selection for specific setups. Features and specifications Function: PCIe x4 to x16 extension cable for signal routing and card relocation. Performance: Supports PCIe 4.0 x4 signaling at a maximum of 64 Gbps. Size and length: Standard listed size 5 cm; cable lengths available from 3 cm to 40 cm and can be customized to match installation needs. Models: M2SM31, M2SM32, M2SM33. Color reference M2SM33TL. Use cases: desktop, server, and test bench integration where PCIe slot placement needs to be adjusted. Practical applications Small form factor PC builds where the GPU or accelerator cannot fit directly above the motherboard slot. The extension cable enables relocation without sacrificing throughput. Test benches and development environments that require frequent card swaps and flexible positioning. The cable simplifies access and reduces wear on motherboard slots. Multicard rigs or expansion enclosures that need organized cable routing and improved cooling. Custom lengths help keep installations neat and maintain signal integrity. Compatibility and installation notes Designed to work with devices that use PCIe x4 and PCIe x16 connectors, including graphics cards and expansion adapters that operate at up to PCIe 4.0 x4. Select the appropriate model and cable length for the required reach and physical layout. Proper mounting and gentle routing help preserve connector integrity and signal performance. This product provides a practical extension solution for relocating PCIe cards while maintaining speed data transmission and offering length for precise installations.
