Pasywny Riser Supermicro 1U RHS 1xPCI-E x8 R1UU-E8R+

The Supermicro 1U RHS 1xPCI-E x8 R1UU-E8R+ is a passive riser card designed for high-density 1U server platforms. It provides a single PCI Express x8 expansion slot while maintaining strict mechanical and airflow constraints of 1U rackmount chassis.

As a passive riser, it relies on the server motherboard for signal integrity and power delivery, without additional active components or controllers. This makes it a robust, low-failure-point solution for enterprise environments.

• Form factor: Dedicated to 1U rackmount systems, optimized for horizontal card installation in limited vertical space.
• Slot position: RHS (Right Hand Side), enabling precise integration in compatible UIO chassis layouts.
• Interface: PCI Express x8 input and PCI Express x8 output, suitable for low-profile PCIe x8 expansion cards (depending on chassis and motherboard support).
• Category: UIO – dedicated to specific server platforms using Universal I/O layout.
• Passive design: No additional electronics, firmware, or management functions, reducing potential points of failure.
• No GPU/NVMe/M.2 support: Intended for standard PCIe expansion only, not for GPU, NVMe, or M.2 devices.
• No thermal sensor or auto-detection: The riser does not provide temperature monitoring or automatic card detection features.

This riser card is suitable for system integrators and administrators who need a reliable PCIe x8 expansion path in 1U servers, while maintaining predictable thermal behavior and mechanical compatibility with UIO-based chassis. Before deployment, verify compatibility with the target motherboard and enclosure, including slot orientation, mechanical clearance, and supported PCIe devices.
