Reverse 90° PCIe x16 Riser

A precision-engineered PCIe 3.0 x16 male-to-female riser card with a fixed 90-degree reverse bend, intended for 2U server architectures where expansion cards must be oriented toward the CPU. Physical size is capped at 107 mm × 61.8 mm × 13.8 mm; net weight is 23 g. Operational temperature span: 0°C to +85°C. Housing material: plastic. Includes only the riser card — no screws, cables, or adapters. The reverse configuration places the female PCIe slot directly above or beside the motherboard’s native x16 slot, enabling upright GPU or accelerator mounting without occupying valuable front-panel I/O real estate. Its low height (13.8 mm) clears most CPU retention brackets and memory heat spreaders, while the lightweight build prevents creep deformation over time. Electrical performance remains fully compliant with PCIe 3.0 base specification, supporting unthrottled bandwidth for data-intensive applications. Used by cloud infrastructure teams and HPC labs to scale GPU density in space-constrained racks, this riser prioritises interoperability, thermal headroom, and mechanical repeatability — not flashy aesthetics or unnecessary features.
