Manufacturer description
Want to show off your graphics card instead of hiding it face-down? The CORSAIR Premium PCIe 3.0 x16 Extension Cable lets you mount your GPU vertically in compatible cases, so the cooler and backplate face the side window. The riser carries the full PCIe 3.0 x16 interface from your motherboard slot to the card. At 300mm long, it has enough slack to route from the slot to a vertical mounting bracket. EMI shielding protects the signal from electromagnetic interference, which matters on a cable running past fans, power cables and the GPU's own power delivery. The cable is built as five separate…

Frequently Asked Questions
How long is the Corsair PCIe riser cable?
The cable is 300mm long, which gives you enough length to route from the motherboard's x16 slot to a vertical GPU mount in compatible cases.
Will this riser work with a PCIe 4.0 or PCIe 5.0 graphics card?
Corsair specifies this cable for PCIe 3.0 x16. The listing makes no PCIe 4.0 or 5.0 claims, so check with Corsair about compatibility and link speed before using it with a newer-generation card.
Does this cable fit any PC case?
It is designed for vertical GPU installation in compatible cases. Your case needs vertical GPU mounting support, and 300mm has to fit the distance between your x16 slot and the mount position.
Will a riser cable cause signal interference or instability?
The cable is EMI shielded to block electromagnetic interference from nearby components and to preserve PCIe 3.0 x16 performance between the slot and the GPU.
Which way does the GPU-side connector face?
The GPU end has a 90-degree female PCIe connector. It reduces cable strain and makes it easier to seat a vertically mounted graphics card. The five banded wires flex to route the cable through tight spaces.
