The CORSAIR Premium PCIe 3.0 x16 Extension Cable is a 300mm riser built with a five-wire banded design and a 90-degree female PCIe connector. It carries full-speed PCIe 3.0, so a graphics card runs at its full potential instead of being throttled by the link. EMI shielding cuts electromagnetic interference between components, and the angled connector makes it easier to route in compact builds.

The cable supports the full capabilities of PCIe 3.0 across all sixteen lanes, so nothing is given up by moving the card off the motherboard slot. A riser that cannot carry full bandwidth costs frame rate, which defeats the point of mounting the card differently. Here the GPU gets the same link it would have plugged in directly.

Because the card no longer has to sit hard against the motherboard, the cable helps keep a compact setup organised and improves airflow through the chassis. A tidier interior looks better through a glass panel and gives the fans a clearer path. Both matter in small cases where every centimetre of clearance counts.

At 300mm the cable gives enough length to reach a vertical mounting position, and the 90-degree female PCIe connector turns the card into place without forcing a bend. That angle minimises cable strain at the connector, which is where a riser is most likely to fail. Vertical GPU installations in compatible cases become straightforward rather than a fight.

The five-wire banded construction makes the cable fully flexible, so it can be threaded through the tightest gaps in a chassis. Flat banding also lies neatly against a panel instead of bulging like a round bundle. That flexibility is what makes routing possible in cases where a stiff riser simply would not fit.

The cable is EMI shielded, which keeps electromagnetic interference from degrading the link even in a dense, high-demand build. Interference is a real concern when a PCIe signal runs alongside power cables and spinning fans inside a metal box. Shielding is what lets the connection hold maximum performance in that environment.

The cable is aimed at gamers and PC builders who want a durable connection between the graphics card and the motherboard rather than a generic riser. It fits an upgrade to a system already running as easily as a build starting from an empty chassis. This is CORSAIR part CC-8900419.

Everything you need to know about this product
The cable is 300mm long, which is enough to reach a vertical mounting position in a compatible case.
It supports full-speed PCIe 3.0 across a x16 connection, so the graphics card is not bandwidth limited.
It has a 90-degree female PCIe connector, which is angled to reduce cable strain during installation.
Yes, it uses EMI shielding to reduce electromagnetic interference between components in a dense build.
Its five-wire banded construction is fully flexible, letting it route through the tightest gaps in a chassis.
Yes. The 300mm length and 90-degree connector are designed to simplify vertical GPU installations in compatible cases.
No. The cable is built for full-speed PCIe 3.0, so the card operates at its peak potential without performance slowdowns.
Moving the card off the motherboard slot opens up the interior, which improves airflow and keeps the build tidier.
