PCI-E 4.0 x16 Riser Cable 200mm

This 200mm PCI-E 4.0 x16 riser cable extends a graphics card connection inside custom or small-form-factor builds. The flexible 1.3mm black cable uses EMI shielding with conducting polymer to maintain signal integrity. It suits builders who need to reposition a GPU vertically or horizontally away from the motherboard slot.

Bandwidth limit of 16Gbps per lane

The cable supports PCI-E 4.0 speeds up to 16Gbps per lane across the full x16 interface. Shielding reduces electromagnetic interference that can degrade high-frequency signals over the 200mm run. Builds requiring PCI-E 5.0 or external cabling cannot use this internal extender.

Male-to-female x16 connector pair

One male and one female PCI Express x16 connector provide a direct pass-through for the graphics card. The terminal gender is fixed, so systems needing a different connector orientation or a x8 electrical link must select another part.

Questions about this item

How do I choose between the available lengths for this riser cable?

This model is the 200mm (8 inch) version; select a different length from the range if your case layout requires a longer or shorter reach.

What does the 16 Gbps bandwidth figure mean once the cable is installed in a system?

It supports the full PCI‑E 4.0 x16 data rate of 16 Gbps per lane, so a graphics card or other x16 device can run at its native speed without bottleneck.

What interface standard does this cable use and what does it cap in practice?

It is built to the PCI‑E 4.0 x16 specification with EMI‑shielded conductors, capping real‑world throughput at the 16 Gbps per lane limit of that standard.
