Vszerda PCIe 4.0 x16 Extender Riser Cable 20 cm

SKU CH-EE6M-AA9YS

PCIe 4.0 x16 riser cable extends a graphics card up to 20 cm with 128 Gbps bandwidth and 180-degree shielded connectors

  • Compatible with RTX 4090 4080 4070 4060 and RX 7900 7800 7700 7600 7500 GPUs
  • Backward compatible with PCIE 3.0 2.0 1.0 for broad motherboard support
  • 128Gbps bandwidth enables full PCIE 4.0 x16 performance
  • 180 degree shielded slots eliminate interference for vertical GPU mounting
  • Slim flat foldable 20 cm cable simplifies routing in tight cases

PCIe 4.0 x16 GPU riser cable

This PCIe 4.0 x16 extender connects a graphics card to a motherboard at a distance of 20 cm. It supports RTX 40 series and RX 7000 series GPUs while remaining backward compatible with PCIe 3.0, 2.0 and 1.0. The cable suits builders who need flexible routing for vertical or custom GPU mounting.

Dual-sided 180-degree ports and EMI shielding

The dual-sided reverse 180-degree ports allow the connector to be flipped for tight clearances. An electromagnetic interference shield on the slots reduces signal degradation when the cable is folded or twisted. These features let the link maintain 128 Gbps throughput in compact cases where straight connectors would not fit.

PCIe 4.0 bandwidth ceiling and length limit

The cable operates at the PCIe 4.0 x16 rate of 128 Gbps, so any platform limited to PCIe 3.0 will not reach that ceiling. The fixed 20 cm length restricts how far the GPU can sit from the slot, and the x16 interface cannot serve storage or networking add-in cards that require a different lane configuration.

Questions about this item

Will the PCIe 4.0 x16 connector or the 180-degree shielded slots need replacement after repeated GPU swaps?

The cable uses a standard PCIe 4.0 x16 interface rated for normal insertion cycles; the 180-degree shielded slots are built into the riser and do not have a separate replacement schedule.

What limits sustained throughput on this 20 cm riser when running at the full 128 Gbps rate?

The 128 Gbps ceiling is set by the PCIe 4.0 x16 specification; signal integrity over the 20 cm flexible PCB and any motherboard or GPU lane-quality margins become the practical limit.

Does the flat foldable cable add noticeable heat or power draw when the GPU runs all day at PCIe 4.0 speeds?

The riser is a passive PCB assembly with no active components, so it adds negligible heat and no measurable power draw beyond the normal PCIe slot allocation.
