Pasywny Riser Supermicro 1U LHS 2xPCI-E 3.0 x8

The passive Supermicro 1U LHS 2xPCI-E 3.0 x8 riser is designed for 1U WIO server platforms that require reliable horizontal expansion of PCI Express cards. It enables installation of two PCIe 3.0 x8 cards on the left-hand side (LHS) slot position without adding active electronic components.

The riser is dedicated to environments where predictable signal integrity, thermal monitoring and controlled configuration are critical, such as data centers, virtualization hosts and network appliances.

• Form factor: Compatible with 1U chassis, WIO category, LHS slot position
• Output type: 2x PCI Express 3.0 x8 for expansion cards
• Input type: (8) PCI-E x8 interface on the motherboard side
• Design: Passive riser – no active signal conditioning components
• Thermal sensor: Integrated sensor for temperature monitoring
• Automatic detection: Support for automatic detection to simplify platform configuration
• GPU support: Not supported
• NVMe support: Not supported
• M.2 support: Not supported

Key technical benefits:

• Optimized for 1U systems: Horizontal card orientation allows effective use of limited height in 1U racks.
• Predictable integration: Dedicated to WIO platforms with LHS slot, reducing mechanical and electrical compatibility risks.
• Thermal control: Built-in thermal sensor provides accurate temperature feedback for system monitoring and fan control strategies.
• Simplified deployment: Automatic detection helps the platform correctly recognize the riser presence and configuration, reducing manual intervention.
• Focused use case: Intended for PCIe expansion cards other than GPU, NVMe or M.2, for example controllers or adapter cards where supported by the host platform.

This riser is suitable for system integrators and administrators building dense 1U infrastructures that require additional PCIe connectivity while maintaining strict control over thermals and system behavior. Before deployment, verify mechanical and electrical compatibility with the specific Supermicro motherboard and chassis model.
