Thunderbolt 5 cable StarTech 80 cm, 80 Gbps (up to 120 Gbps), 240W PD, 8K@60Hz, Thunderbolt/USB-C male–male — white

Certified StarTech Thunderbolt 5 cable, 0.8 m length with male-to-male USB-C connectors, provides ultra high-performance connectivity for Thunderbolt 5-enabled devices. It supports up to 80 Gbps bidirectional bandwidth with a Boost Mode that reallocates lanes to deliver up to 120 Gbps transmit and 40 Gbps receive when display-intensive throughput is required. The cable carries video up to 8K at 60 Hz (DisplayPort 2.1 Alt Mode with DSC and HDR), supports PCIe 4.0 data paths for external GPUs and storage, and delivers up to 240W Power Delivery for high-performance laptops. It is backward compatible with Thunderbolt 4/3, USB4 (40 Gbps) and USB 3.2 (10 Gbps).

Advantages

The cable doubles Thunderbolt 4 bandwidth with 80 Gbps bidirectional throughput and offers an asymmetric Boost Mode (120 Gbps transmit / 40 Gbps receive) for display-heavy workflows. Certified for Thunderbolt 5 performance, it ensures compatibility across mixed hardware environments. The construction includes braided alloy shielding and shielded coaxial conductors to minimize EMI, a halogen-free TPE outer jacket tested for repeated bending, robust strain reliefs, and nickel-plated connectors rated for high insertion counts, supporting reliable long-term use.

Suitable for

• Connecting high-performance laptops (for example 16-inch MacBook Pro with M4 Pro/Max) to docks, displays, or external storage
• Driving one or two 8K 60Hz displays or high-refresh 4K displays for video editing and color-accurate workflows
• High-bandwidth external GPU, NIC, or PCIe storage chassis connections
• Charging power-hungry laptops and devices up to 240W via USB Power Delivery

How to use

Connect the male USB-C connector on each cable end to the USB-C/Thunderbolt ports on your devices such as a laptop and a dock, display, or external enclosure. For maximum performance, use Thunderbolt 5 ports on both ends; the cable will negotiate lower speeds when connected to Thunderbolt 4, USB4, or USB-C hosts. Enable DisplayPort Alt Mode on compatible devices to deliver video over the cable and ensure your host and display support the targeted resolution and refresh rate. When using Boost Mode for high display bandwidth, confirm host and peripheral support for Thunderbolt 5 asymmetric lane allocation.

Usage recommendations

Route the cable without sharp bends and avoid tight kinks; allow strain reliefs to reduce stress near connectors. For sustained high-bandwidth video workflows or high-power charging, verify that both connected devices support Thunderbolt 5 features and 240W USB Power Delivery to achieve expected performance.
