SKU CH-3P0F-G64DH

A 1 m Thunderbolt cable delivering 80 Gbps bidirectional bandwidth, 120 Gbps boost mode, 240 W Power Delivery and 8K 60 Hz video support

  • 80 Gbps bandwidth doubles Thunderbolt 4 capacity
  • 120 Gbps boost mode handles display-intensive workloads
  • 8K 60 Hz video via DisplayPort 2.1 Alt Mode with HDR
  • 240 W Power Delivery charges high-performance laptops
  • 64 Gbps PCI Express 4.0 support for GPUs and storage

Thunderbolt 5 Cable 80Gbps Bandwidth

This Thunderbolt 5 cable delivers 80Gbps bidirectional bandwidth, doubling the capacity of Thunderbolt 4. It supports 120Gbps boost mode for display-intensive applications and PCI Express 4.0 at 64Gbps for external GPUs, NICs and storage. The cable is backward compatible with Thunderbolt 4, Thunderbolt 3, USB4 and USB 3.2 devices.

Thermals and Power Delivery

The cable provides 240W Power Delivery EPR charging for high-performance laptops during sustained workloads. Passive copper construction operates without active cooling or added noise in normal use. Power draw scales with the connected host and peripheral requirements.

Build Quality and Daily Use

Certified construction ensures reliable signal integrity at 80Gbps and 120Gbps speeds over the 1m length. DisplayPort 2.1 Alt Mode enables up to 8K 60Hz or 4K 240Hz video with DSC, HDR and 10-bit colour. White jacket offers clean routing visibility on desk setups. Not for users needing longer cable runs beyond the certified 1m length.

Highlights

Questions about this item

How do I connect the StarTech Thunderbolt 5 cable to get 80 Gbps bidirectional bandwidth?

Plug each end into Thunderbolt 5 ports on host and device; the link negotiates 80 Gbps automatically. The step people miss is using a Thunderbolt 5 port — USB4 or Thunderbolt 4 ports cap at 40 Gbps.

Will the 240 W Power Delivery rating degrade over time?

The cable is rated for 240 W EPR from day one. No internal maintenance is needed; replace only if the connector housing cracks or pins bend.

At what point does sustained 8K 60 Hz video hit a bandwidth ceiling?

DisplayPort 2.1 Alt Mode with DSC fits 8K 60 Hz inside the 80 Gbps link. The first hard limit is the 80 Gbps bidirectional bandwidth; boost mode reaches 120 Gbps for lighter display loads.
