Pasywny Riser Supermicro 1U LHS 1x PCI-E x8

The passive Supermicro 1U LHS 1x PCI-E x8 riser is designed to provide a reliable horizontal expansion slot in 1U rackmount systems. It routes a PCI Express x8 signal from the motherboard to a single PCI-E x8 slot positioned on the left-hand side (LHS), enabling the installation of compatible low-profile expansion cards in space-constrained server environments.

This riser uses a PCI-E x8 + HT connector input and exposes one PCI-E x8 output. As a passive design, it does not include active components or signal conditioning, relying entirely on the host platform's electrical characteristics. It is intended for use in 1U chassis that explicitly support this riser configuration.

Benefits in 1U environments

• Enables horizontal installation of a single PCI-E x8 expansion card in ultra-low 1U chassis.
• Optimizes use of limited internal space while maintaining standard PCI Express connectivity.
• Passive construction minimizes potential failure points associated with active electronics.
• Suitable for applications where a single add-in card (e.g. controller or adapter) is required without GPU, NVMe or M.2 functionality.

Before deployment, verify mechanical and electrical compatibility with the target Supermicro motherboard and 1U chassis, including LHS slot orientation and connector type.
