Pasywny Riser Supermicro 1U LHS 1xPCI-E 3.0 x16 R1UG-E16-UP

The Supermicro R1UG-E16-UP is a passive 1U riser card designed to provide reliable PCI Express expansion in high-density server platforms. With a single PCI-E 3.0 x16 slot in LHS (left-hand side) position, it enables installation of GPU or other high-bandwidth PCIe adapters in compatible 1U chassis.

This riser uses a PCI-E x16 input and exposes a PCI-E x16 output, ensuring a direct, non-active signal path without additional processing components. The design is optimized for environments where signal integrity, mechanical stability and predictable performance are critical.

• Form factor: Dedicated for 1U chassis (LHS slot position)
• Interface input: PCI Express x16
• Interface output: PCI Express x16
• PCIe generation: PCI-E 3.0 x16
• GPU support: Yes – suitable for GPU-capable configurations
• NVMe support: No – not intended for PCIe NVMe backplanes
• M.2 support: No – no M.2 interfaces provided
• Thermal sensor: Not available
• Automatic detection: Yes – supports automatic detection in compatible platforms

As a passive riser, the R1UG-E16-UP does not include active signal conditioning or additional management logic. This reduces complexity and potential points of failure, making it suitable for data center and enterprise deployments where uptime and consistent behavior are essential.

The riser is intended for use in compatible 1U server chassis that require left-hand side PCIe expansion, particularly for GPU, accelerator or other high-bandwidth PCIe cards. Before deployment, it is recommended to verify mechanical and electrical compatibility with the target chassis and motherboard.
