The Corsair 2500 Series Vertical GPU Mount Kit in black is an accessory for Corsair's 2500D and 2500X cases that lets a graphics card be mounted vertically instead of in the standard horizontal expansion-slot orientation — a popular way to showcase a GPU's own cooler shroud and RGB lighting through a case's tempered-glass side panel, and a genuine option on cases built with a supporting bracket mount point. The kit includes a vertical mounting bracket, a 175mm PCIe 4.0 riser cable to physically extend the card's PCIe connection from the motherboard slot to the vertical bracket position, 4x PCI slot covers for the rear I/O opening the card now occupies vertically, and the screws and standoffs needed for a complete installation. Because the riser cable is rated for PCIe 4.0, it preserves full bandwidth and signal integrity for a modern high-bandwidth graphics card, avoiding the performance loss or instability that a cheaper, lower-spec riser cable can introduce. It is compatible specifically with the Corsair 2500D and 2500X case models, not a universal riser kit for other cases.
