Powered riser adapter — the USB cable is designed for easy routing, allowing the graphics card to be placed flexibly. Computer adapter — enables connecting multiple graphics cards to a single motherboard simultaneously. PCI Express extension adapter — features a 6pin interface and a 12V enhanced DCDC power supply, making the graphics power supply independent from the motherboard and reducing the load on the motherboard when multiple graphics cards are connected. PCIe 1x to 16x adapter — when plugging or unplugging the PCIe extension cable, the computer must be powered off and then plugged in. Key benefits Independent GPU power supply reduces burden on the motherboard in multiGPU setups. Flexible GPU placement and routing with the powered riser design for cleaner builds. Simplified multiGPU connectivity from a single motherboard. Specifications and usage notes Power interface: 6pin PCIe power input with a 12V enhanced DCDC supply for GPU power isolation from the motherboard. PCIe extension: provides 1x to 16x PCIe adapter capability to support multiple GPUs. Safety note: always power off the computer before plugging or unplugging the PCIe extension cable. Use scenarios Cryptocurrency mining rig: run multiple graphics cards from one motherboard while keeping GPU power independent to improve system stability. MultiGPU workstation: a single host board drives several GPUs for rendering, video processing, or parallel compute tasks without overloading the motherboard power rails. GPU compute server or AI/ML setup: enables scalable GPU deployment in a compact form factor by distributing power delivery directly to GPUs. Compatibility and limitations Designed to connect multiple GPUs to one motherboard using PCIe 1x to 16x configuration. Requires a 6pin PCIe power connection and the 12V DCDC power supply included with the extension setup. For safety and reliability, ensure the system is powered off before connecting or disconnecting PCIe extension components.
