Flat 200mm PCIe 4.0 x4 riser cable with right-angle female connector

BUCIER

BUCIER PCIe 4.0 X4 Riser Cable 200mm

SKU CH-50F1-84P19

A 200 mm PCIe 4.0 x4 riser cable with 64-pin full-function support for x1, x4, x8 and x16 cards, 180-degree female slot, 30 AWG silver-plated copper conductors wrapped in Teflon and aluminium foil.

  • PCIe 4.0 x4 bandwidth up to 8 GB/s for fast add-in cards
  • 200 mm length with 180-degree connector for flexible routing in tight cases
  • 30 AWG silver-plated copper with Teflon and foil shielding resists EMI and heat
  • 64-pin full-function slot accepts x1, x4, x8 and x16 cards
  • Backward compatible with PCIe 3.0, 2.0 and 1.0 devices

PCIe 4.0 x4 Riser Cable for Expansion Cards

This 200 mm riser cable carries a PCIe 4.0 x4 link with up to 8 GB/s theoretical bandwidth and remains compatible with 3.0, 2.0 and 1.0 devices. It targets builders who need to relocate M.2, Wi-Fi, FireWire, USB or sound cards away from the motherboard slot. The 64-pin connector accepts x1, x4, x8 or x16 add-in cards.

Shielded 30 AWG Construction Limits Interference

Each differential pair is wrapped in Teflon and aluminium foil around a silver-plated copper core rated for 30 AWG. The shielding provides electrical insulation and resists electromagnetic interference during normal operation. A 180-degree female socket orientation lets the installed card sit parallel to the motherboard for cleaner routing.

Plug-and-Play Connection With Anti-Static Handling

The cable requires no drivers or configuration beyond seating the card in the female slot and the male end in the board. It is not designed for hot-swapping, so power down before changes. An anti-static bag protects the gold fingers; avoid touching them to prevent contamination that could degrade signal quality.

Questions about this item

How do I install the 200 mm PCIe 4.0 x4 riser cable and what step is often missed?

Connect the male end to the motherboard slot and the PCIe card to the 180-degree female socket; the step often missed is avoiding contact with the gold fingers, as handprints degrade signal quality.

What maintenance or replacement will this 64-pin riser cable need over time?

No scheduled maintenance is required; replace the cable only if physical damage occurs to the 30 AWG silver-plated copper conductors or the Teflon and aluminium foil shielding.

What limit appears first when the cable runs at PCIe 4.0 x4 speeds under sustained load?

The 8 GB/s theoretical bandwidth ceiling of the PCIe 4.0 x4 link is the first limit reached during sustained high-throughput transfers.
