BONAEVER PCIe 3.0 16x Flexible Riser Cable 20cm 180°

Product identity

The BONAEVER PCIe 3.0 16x flexible riser cable extends a graphics card slot by 20 centimetres with a 180-degree connector orientation. It serves builders who need to reposition a GPU in a custom loop, a small-form-factor case or a vertical-mount bracket. The black EMI-shielded cable suits new system builds or upgrades where the standard slot location is impractical.

Decisive specification

The cable carries a PCIe 3.0 16-lane signal across a 20 cm length with 180-degree ends, so the lane count and generation must match the host slot and the graphics card exactly. A PCIe 4.0 or 5.0 platform will negotiate down to 3.0 speeds, while a x8 or x4 slot will limit bandwidth accordingly. Builders who require full 4.0 or 5.0 throughput cannot use this riser.

Build integration

The flexible shielded ribbon routes around drive cages, radiators or power-supply shrouds without sharp bends, freeing the primary PCIe slot for other expansion cards. Gold-plated contacts and high-quality solder points maintain signal integrity over the 20 cm run. The 180-degree connector clears low-profile rear brackets, but the fixed length means the GPU must sit within 20 cm of the motherboard slot.
