Flat black 20 cm PCIe 4.0 riser cable with 180 degree gold connectors and shielded ribbon design

Vszerda

Vszerda PCIe 4.0 riser cable 20cm 180 degree

SKU CH-DR27-B6V33

Extends a graphics card 20 cm with a 180-degree turn, using shielded PCIe 4.0 wires that deliver 64 GB/s bi-directional bandwidth and 85 ohm impedance for lossless signal quality

  • PCIe 4.0 support delivers 64 GB/s bandwidth for modern GPUs
  • Hand-soldered gold-plated contacts ensure signal integrity and low attenuation
  • Individual lane shielding blocks EMI and crosstalk between channels
  • Sectional design promotes airflow to reduce operating temperatures
  • 20 cm length with 180-degree connector enables flexible routing in tight cases

Flexible PCIe 4.0 Riser Cable 20 cm 180°

This 20 cm extender moves a graphics card away from the motherboard slot using a 180-degree connector orientation. Hand-soldered gold-plated contacts and pure copper tinned cores maintain signal integrity across the link. The cable supports PCIe 4.0, 3.0, 2.0 and 1.0 speeds for broad compatibility. A sectional layout improves airflow around the routing path.

Builders routing GPUs in tight or custom chassis

The flexible sheath and removable buckle let the cable bend sharply and stay hidden during installation. No BIOS changes are required — just plug in and power on. Individual lane shielding reduces EMI and crosstalk for stable 64 GB/s bi-directional throughput. Buyers who need a longer reach or a straight connector should look at other options.

85 ohm impedance tuning for PCIe 4.0 signalling

The conductors and connectors are re-engineered to an 85 ohm target that matches the 4.0 specification. This controlled impedance keeps the link error-free at full 4.0 speeds without BSOD or WHEA faults. If your platform only runs at 3.0 or below the cable still works, but the 85 ohm design is what guarantees 4.0 performance.

Questions about this item

What clearance does the 20 cm cable with 180 degree connector need inside the case?

The 20 cm length and 180 degree connector let the cable fold flat against the motherboard, so it fits in tight small-form-factor builds without blocking airflow.

Which step do builders often miss when seating the gold-plated contacts on this riser?

Push the connector until the removable buckle clicks; a partial seat causes signal errors even though the cable supports PCIe 4.0 85 ohm signalling.

When should the cable be inspected or replaced to keep 64 GB/s throughput?

Check the shielding and solder joints if you move the GPU or change cases; repeated sharp bends can degrade the individual laneway shielding over time.
