The Supermicro RSC-W2-66 Riser Card is an enterprise-grade 2U WIO (Workstation I/O) left-side passive riser module designed for Supermicro rack server chassis. It provides PCIe expansion capability by routing motherboard PCIe lanes to external add-in cards such as NICs, RAID controllers, and GPU/accelerator cards.

This riser is specifically engineered for compatible Supermicro 2U WIO server platforms, where space-efficient and high-density PCIe expansion is required. It is a passive riser, meaning it does not contain active electronics—just signal routing for stable PCIe connectivity in enterprise environments.
