White Thunderbolt 5 cable, 1.5ft length, USB-C connectors on both ends

STARTECH

STARTECH 1.5ft 50cm Thunderbolt 5 Cable 80Gbps/120Gbps 240W PD 8K 60Hz White

SKU CH-BA2G-QF9BA

A 1.5 ft Thunderbolt cable delivers 80 Gbps bidirectional bandwidth and up to 120 Gbps boost mode for 8K 60 Hz video, 240 W power delivery, and backward compatibility with Thunderbolt 4.

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

What this cable does

This StarTech Thunderbolt 5 cable delivers 80 Gbps bidirectional bandwidth, doubling the capacity of Thunderbolt 4. A 120 Gbps boost mode handles display-intensive applications. It supports DisplayPort 2.1 Alt Mode for up to 8K 60Hz or 4K 240Hz video with DSC, HDR and 10-bit color.

Build and daily use

The 1.5ft length suits tight desk setups and short rack runs. Connectors carry PCI Express 4.0 at 64 Gbps for external GPUs, NICs and storage enclosures. 240W Power Delivery EPR charges high-performance laptops through the same link. Backward compatibility covers Thunderbolt 4, Thunderbolt 3, USB4 at 40 Gbps and USB 3.2 at 10 Gbps.

Upgrade path and limits

Replaces Thunderbolt 4 or USB4 cables when 80 Gbps sustained throughput or 120 Gbps boost bandwidth is required for PCIe devices or 8K displays. The jump is worth it for workloads that saturate 40 Gbps links. Not for buyers who need longer reach than 1.5ft or who only run 10 Gbps peripherals.

Highlights

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

Questions about this item

What bandwidth does the Thunderbolt 5 cable provide and what does that cap in practice?

The cable delivers 80 Gbps bidirectional bandwidth and a 120 Gbps boost mode for display-intensive workloads, doubling Thunderbolt 4 capacity.

What physical length and connector type does this Thunderbolt 5 cable use?

It is a 1.5 ft (50 cm) white cable with USB-C connectors on both ends for direct device-to-device or device-to-dock connections.

How do I install the Thunderbolt 5 cable and what step do people often miss?

Plug each USB-C end firmly into the Thunderbolt 5 ports on both devices; the common mistake is not seating the connectors fully, which prevents the 80 Gbps link from negotiating.
