This is sufficient for mining, AI inference, and most rendering tasks. Gaming on these GPUs is possible but not optimal. Motherboard BIOS: Some motherboards may need “Above 4G Decoding” or “Resizable BAR” enabled in BIOS for multiple GPUs. Riser Cables Required: This card provides USB ports only – you must use USB 3.0 PCIe riser cables to connect GPUs. Power: Each GPU needs separate 6-pin/8-pin power from your PSU. The multiplier card draws minimal power from the PCIe slot.
