  • Backward compatible with PCIe 3.0, 2.0 and 1.0 slots
  • 180° reverse ports enable vertical GPU mounting in tight cases
  • Slim, flat 40 cm cable folds easily for clean cable routing
  • Plug-and-play installation requires no drivers or extra power connectors

40 cm PCIe 4.0 x16 riser cable

This 40 cm riser cable carries a PCIe 4.0 x16 link between motherboard and graphics card. It supports RTX 4000 series cards such as the 4090, 4080, 4070 and 4060, plus RX 7000 series GPUs including the 7900, 7800, 7700, 7600 and 7500. The slim, foldable construction suits vertical mounting and tight chassis layouts.

Upgrade from PCIe 3.0 or older risers

Builders moving from a PCIe 3.0, 2.0 or 1.0 extender gain the 128 Gbps bandwidth of the 4.0 standard. The jump matters when the graphics card can saturate the wider pipe, especially with high-resolution textures and compute workloads. If the current riser already runs at 4.0 speeds, this cable adds length and flexibility rather than throughput.

Limited by 40 cm length and x16 slot spacing

The 40 cm reach restricts placement to nearby vertical brackets or adjacent slots. The 180 degree shielded connectors demand clearance for the reverse orientation, so very compact cases may not accommodate the bend radius. Systems that need longer runs or multiple risers cannot use this single cable.

Questions about this item

How much clearance does the 40cm riser cable need for a 180-degree reverse mount?

The 40cm length and slim flat design let you fold or twist the cable to fit tight cases while keeping the x16 link at 128Gbps.

Which PCIe slot version on the motherboard is required for the x16 interface to work at full speed?

Plug the riser into any PCIe 4.0 x16 slot; it is backward compatible with 3.0, 2.0 and 1.0 slots but will run at the slot's native rate.

When should the riser cable be inspected or replaced after installation?

Check the cable if you reroute it, hear intermittent link drops, or upgrade to a newer GPU; the flexible PCB tolerates repeated bending but fatigue can appear over time.
