White Thunderbolt 5 cable 2.6ft 80cm with Thunderbolt connectors

STARTECH

STARTECH Thunderbolt 5 Cable 2.6ft 80cm 80Gbps 120Gbps 240W PD 8K 60Hz White

SKU CH-CAH7-RCKJ3

Thunderbolt 5 cable delivers 80 Gbps bidirectional bandwidth and up to 120 Gbps boost mode with 240W Power Delivery and 8K 60Hz video support

  • 80 Gbps bidirectional bandwidth for high-speed data transfers
  • 120 Gbps boost mode for display-intensive applications
  • 240W Power Delivery EPR for charging high-performance laptops
  • 8K 60Hz video with DisplayPort 2.1 Alt Mode
  • Backward compatible with Thunderbolt 4/3, USB4 (40 Gbps), and USB 3.2 (10 Gbps)

Thunderbolt 5 Cable 80 Gbps

The StarTech Thunderbolt 5 cable delivers 80 Gbps bidirectional bandwidth and up to 120 Gbps boost mode for display-heavy workflows. It suits creators and developers connecting high-performance laptops to docks, eGPU enclosures or 8K displays. The 2.6 ft length keeps desktop setups tidy without excess slack. It is not for users needing longer runs across a room or between racks.

Bandwidth Headroom and Display Limits

Certified bandwidth handles PCIe 4.0 at 64 Gbps for external GPUs, NICs and storage arrays. DisplayPort 2.1 Alt Mode drives one 8K 60 Hz or 4K 240 Hz stream with DSC, HDR and 10-bit colour. The 120 Gbps boost reserves extra headroom for demanding video pipelines. It cannot drive dual 8K panels or exceed the single-stream video ceiling defined by the spec.

Build Quality and Daily Use

The white jacket and certified construction meet CE and FC marks for regulatory compliance. 240 W Power Delivery EPR charges high-performance laptops while data and video run simultaneously. Backward compatibility drops to Thunderbolt 4, USB4 at 40 Gbps and USB 3.2 at 10 Gbps on older hosts. The fixed length limits repositioning; buyers needing flexible routing should consider longer or active alternatives.

Questions about this item

Will this Thunderbolt 5 cable work with my existing Thunderbolt 4 dock and USB4 devices?

Yes, the cable is backward compatible with Thunderbolt 4, Thunderbolt 3, USB4 at 40 Gbps, and USB 3.2 at 10 Gbps, so older docks and peripherals will connect and function at their rated speeds.

How can I verify the cable is delivering the full 80 Gbps bandwidth and 240W charging after I plug it in?

Check your laptop or dock firmware utility for a Thunderbolt 5 link at 80 Gbps and confirm the power contract shows 240W; the cable carries the certified Thunderbolt 5 markings required for that negotiation.

Does the 2.6ft white cable include any adapters or do I need to buy a separate DisplayPort 2.1 cable for 8K 60Hz video?

The box contains only the Thunderbolt 5 cable itself; no adapters are included, but DisplayPort 2.1 Alt Mode runs natively over the same connector so a separate DP cable is not needed for 8K 60Hz output.
