Pasywny Riser Supermicro 1U RHS 2xPCI-E 3.0 x16 R1UG-2E8AR+II

The Supermicro R1UG-2E8AR+II is a passive PCI Express riser designed for 1U server platforms that require reliable expansion of GPU or add-in cards in space-constrained environments. It provides two PCI-E 3.0 x16 output slots from a PCI-E x8 input interface, optimized for right-hand-side (RHS) slot positioning in compatible 1U chassis.

This riser is intended for GPU-capable configurations where low latency and stable signal integrity are critical. Passive design means there are no active electronic components, which reduces potential failure points and simplifies maintenance. Automatic detection support facilitates correct recognition of installed cards by the host system without additional configuration.

• Form factor: Dedicated for 1U chassis installations
• Slot position: RHS (right-hand-side) configuration
• Output interface: 2x PCI-E 3.0 x16
• Input interface: PCI-E x8
• GPU support: Yes, suitable for GPU expansion in 1U servers
• NVMe support: Not supported
• M.2 support: Not supported
• Thermal sensor: Not available
• Auto-detection: Supported for installed add-in cards

Key benefits

• Optimized for 1U servers: Enables installation of PCI-E add-in cards in very low-profile chassis without mechanical interference.
• GPU-ready design: Supports GPU deployment in dense environments, improving compute density per rack unit.
• Passive architecture: No additional power draw or active components, contributing to higher reliability and simplified servicing.
• Clean integration: RHS layout helps maintain structured internal cabling and airflow paths in compatible 1U enclosures.

This riser is dedicated to environments where deterministic behavior and mechanical compatibility are more important than feature overload. It does not provide NVMe, M.2 or thermal monitoring functions, focusing instead on robust PCI-E expansion for GPU and other compatible cards within 1U systems.
