Flat green PCB riser with 4x and 16x gold-edge slots linked by 15 cm flexible ribbon cable

Vszerda

Vszerda PCI-E 4X to 16X riser cable 15 cm

SKU CH-4ABQ-C0XBA

Extends a PCIe x4 slot to accept x16 cards at x4 speed with a 15 cm flexible cable and 17 cm total length

  • Extends a PCIe 4X slot to full 16X physical size
  • 15 cm flexible cable fits tight 1U and 2U chassis
  • Soft high-quality cable bends easily for clean routing
  • Gold-finger cover and dust-proof design protect contacts
  • Bolted PCB-to-cable joints prevent tearing and short circuits

PCI-E 4X to 16X riser for compact builds

This 15 cm flexible cable converts a PCIe x4 slot into a full-length x16 connector, letting a graphics card sit away from the motherboard. It operates at x4 electrical speed while accepting x1, x4, x8 or x16 cards. The design targets 1U, 2U and standard ATX or BTX chassis where space is tight.

Signal integrity and thermal profile

High-quality axial cable supports PCIe Gen3 8 Gbps with low attenuation, and the PCB is bolted to prevent solder-point stress. No active cooling is present, so the extender adds negligible heat and zero noise. The gold-finger cover keeps contacts clean during installation and service.

Sustained load behaviour

Under continuous bandwidth demand the link remains at x4 Gen3 rates; latency and throughput do not degrade beyond the electrical width limit. Builders who need x8 or x16 electrical bandwidth for compute workloads should choose a different riser. The bolted PCB and dustproof cover maintain contact reliability over long runs.

Questions about this item

How do I connect the 4X plug to the motherboard and the 16X slot to the graphics card, and what is the step people often miss?

Insert the 4X edge connector into a PCIe x4 slot on the motherboard and seat the graphics card into the 16X socket on the riser; the step often missed is removing the golden finger protection cover from the 16X slot before installing the card.

What part of this riser will need replacement first after long-term use?

The flexible 15 cm cable and its solder joints on the PCB are the components most likely to require replacement after repeated bending or thermal cycling.

What bandwidth limit appears first when the graphics card runs sustained workloads through this riser?

The riser operates at PCIe 4X electrical speed, so the 4X lane ceiling is the first bandwidth limit encountered under sustained load.
