PCI-E 4.0 x16 300 mm riser cable

This 300 mm extender connects a PCI Express 4.0 x16 graphics card to the motherboard slot. Flexible EMI shielding preserves signal quality at the longer length. A straight connector orientation suits vertical mounting brackets. The cable is new and ready for installation.

Builders routing a GPU away from the motherboard

The 300 mm reach fits most vertical-mount cases and open-bench layouts. Builds that keep the card directly in the slot do not need this extender. Systems limited to PCI Express 3.0 signalling will not gain 4.0 bandwidth from the cable alone.

300 mm length with PCI Express 4.0 x16 support

The cable maintains full 4.0 x16 throughput at 300 mm thanks to shielded construction. Shorter 200 mm runs are also covered by the same lossless design. Verify case clearance for the 300 mm route before purchase.

Questions about this item

What clearance does the 300 mm cable need for a vertical GPU mount?

The 300 mm length gives 11.80 in of routing space; allow extra room for the rigid PCB ends and standoffs so the female connector seats fully without stress on the motherboard slot.

Which orientation do the straight connectors require during installation, and what step is often missed?

Align the male end with the motherboard PCIe 4.0 x16 slot and the female end with the add-in card, then press both straight connectors in evenly — forgetting to secure the standoffs leaves the cable bearing the card weight.

When should the EMI-shielded riser be inspected or replaced?

Check the shielding and connector pins whenever the GPU is reseated or the case is moved; replace the cable if the flexible section shows creases, the PCB ends crack, or signal errors appear at PCIe 4.0 speeds.
