Avantalk PCIe 3.0 x4 Extension Cable 180° 20/24cm Black

SKU CH-TQ09-FSS68

A PCIe 3.0 x4 extension cable with a 180-degree connector, 20 cm flexible length and 24 cm total reach for tight 1U or 2U chassis

  • Flexible 20 cm cable fits tight 1U and 2U chassis
  • 180° connector angle allows routing in any direction inside the case
  • Gold-plated contacts deliver stable PCIe 3.0 x4 8 Gbps signalling
  • Bolted PCB reinforcement prevents solder-point tears and short circuits
  • Dust-proof caps protect unused connectors during installation

PCIe 3.0 x4 Extension Cable

This Avantalk PCIe 3.0 x4 extension cable routes a graphics card or expansion board away from the motherboard slot. The 180-degree connector lets the cable fold back on itself for tight 1U or 2U chassis where a straight riser will not fit. It is built for indoor workstations and servers that need flexible placement of a single PCIe 4x device. The gold-plated contacts and bolted PCB reinforce the solder joints against vibration.

Thermals Noise and Power

The cable itself draws no power and adds no active cooling, so it creates no noise and generates no measurable heat. Its high-quality axial construction keeps signal attenuation low, preserving the PCIe Gen 3 8 Gbps link without throttling. Because the assembly is entirely passive, system thermals and fan curves remain unchanged. The dust-proof caps protect the connectors during installation and service.

Build Integration

The 20 cm flexible tail and 24 cm total length give enough reach to route around drive cages or power supplies in shallow rackmount cases. The extremely soft, compact cable bends in any direction without kinking, freeing up the motherboard slot area for airflow or additional cards. Bolts and nuts secure the PCB to the bracket, preventing the cable from tearing loose under vibration. Buyers who need longer runs or multiple risers should look elsewhere.

Questions about this item

How do I route the 20 cm flexible cable into a 1U or 2U chassis without stressing the 180° connector?

Bend the soft cable gently along the chassis floor, keep the gold-plated connector flat against the motherboard slot, and tighten the bolts and nuts that secure the PCB to prevent the solder points from tearing.

What upkeep does the gold-plated PCIe 3.0 x4 connector need over time?

Keep the dustproof cap on when the cable is not seated, and reseat the connector if intermittent contact appears after many insertions.

At what sustained throughput does signal integrity become the limiting factor?

The cable is rated for stable PCIe Gen 3 8 Gbps operation, so sustained transfers at that rate are the practical ceiling.
