Pasywny Riser Supermicro 1U RHS 1xPCI-E 3.0 x8 R1UFF-E8R

The Supermicro R1UFF-E8R is a passive 1U riser card designed for high-density rack systems in the FatTwin family. It provides a single PCI Express 3.0 x8 slot on the right-hand side (RHS) position, enabling reliable expansion of PCIe devices in 1U chassis.

This riser focuses on signal integrity and mechanical compatibility with selected Supermicro 1U FatTwin enclosures. Automatic detection support simplifies system configuration and helps ensure correct identification of the installed expansion card by the platform firmware and operating system.

• Form factor: 1U riser card for FatTwin platforms
• Slot position: RHS (right-hand side)
• Input interface: PCI Express 3.0 x8
• Output interface: PCI Express 3.0 x8
• Operation type: Passive riser (no active signal conditioning)
• Automatic detection: Yes
• GPU support: No
• NVMe support: No
• M.2 support: No
• Thermal sensor: No
• Compatible enclosures: Selected 1U FatTwin chassis (RHS position)

Key benefits

• Optimized for 1U FatTwin – mechanical layout and connector orientation are tailored for the RHS slot in compatible Supermicro chassis, supporting clean cable routing and proper airflow.
• Stable PCIe 3.0 x8 connection – provides a direct passive link between the motherboard PCIe slot and the expansion card, suitable for controllers and adapters designed for PCIe 3.0 x8.
• Simplified integration – automatic detection support helps platforms correctly recognize the riser configuration, reducing manual setup effort.
• Focused design – no GPU, NVMe or M.2 support, and no thermal sensor, making it a straightforward choice where a single PCIe x8 slot is required without additional onboard functions.

This riser is intended for system integrators and administrators building or maintaining Supermicro FatTwin 1U servers that require a single PCIe 3.0 x8 expansion slot on the RHS, while keeping the platform layout compact and electrically robust.
