Pasywny Riser Supermicro 1U RHS 1xPCI-E 3.0 x16 R1UG-E16AR+II

The Supermicro R1UG-E16AR+II is a passive 1U RHS riser designed for high-density server environments that require reliable PCI Express expansion without adding active components or complexity. It enables installation of a single PCI-E 3.0 x16 expansion card, such as a GPU, in compatible 1U chassis.

By using a passive riser, the PCI-E signal path remains transparent to the system, minimizing potential points of failure and simplifying maintenance. The right-hand-side (RHS) slot position is optimized for 1U layouts where vertical clearance is limited and expansion cards must be installed parallel to the motherboard.

• Form factor: Dedicated for 1U chassis with RHS slot orientation
• Interface input: PCI-E x16 (to motherboard)
• Interface output: PCI-E 3.0 x16 (to expansion card)
• GPU support: Yes – suitable for compatible GPU accelerators
• NVMe support: No – not intended for NVMe add-in cards
• M.2 support: No – no integrated M.2 interfaces
• Thermal sensor: Not included – no onboard thermal monitoring
• Automatic detection: Supported – transparent to the host system

Key benefits

• Optimized for 1U servers: Allows horizontal installation of a full PCI-E x16 card in low-profile 1U chassis.
• Passive design: No additional active components, firmware or drivers required, simplifying integration and reducing potential failure points.
• Clean signal routing: Direct PCI-E 3.0 x16 connectivity for bandwidth-demanding devices such as GPUs.
• Infrastructure-friendly: Automatic detection ensures that the riser is effectively transparent to the system configuration.

This riser is intended for use in compatible 1U Supermicro-based platforms where a right-hand-side PCI-E x16 expansion slot is required. Check chassis and motherboard compatibility before deployment.
