Supermicro Riser Card RSC-W-68G5 - 1U LHS WIO Card, 2x PCIe 3.0 Slots (x16/x8)

In a dense 1U server deployment, every PCIe slot counts. The Supermicro RSC-W-68G5 riser card lets you add two expansion cards to your Supermicro WIO-series motherboard, turning a compact chassis into a versatile workhorse for networking, storage, or compute acceleration. It mounts directly onto the left-hand side riser connector, providing a x16 and an x8 PCIe 3.0 slot without consuming additional rack space.

Key specifications

• Form factor: 1U left-hand side (LHS) riser card for WIO chassis
• PCIe generation: PCIe 3.0
• Total slots: 2 (one x16 electrical, one x8 electrical; both physical x16)
• Connector: proprietary Supermicro riser connector
• Compatible motherboards: Supermicro X10DRW, X11DRW (WIO series)
• Application: server, workstation

Why choose it

This riser card is engineered specifically for Supermicro WIO motherboards, ensuring a perfect fit and reliable signal integrity. The mix of x16 and x8 slots lets you balance high-bandwidth cards like GPUs or NVMe adapters with lower-bandwidth networking or storage controllers. Its 1U LHS design maximizes expansion capability in space-constrained environments.

Ideal use cases

• Adding a GPU for edge AI inference in a 1U server
• Installing an additional network interface card (NIC) for increased throughput
• Expanding storage with an HBA or RAID controller
• Building a compact virtualization host with multiple I/O options

Good to know

The riser card is a direct-fit component for Supermicro 1U WIO chassis. It does not include any cables or brackets; installation is tool-less and requires only a compatible motherboard with an available LHS riser slot. Verify your chassis model supports left-hand side riser placement before purchase.
