Thunderbolt 5 cable StarTech 0.5 m (50 cm), 80 Gbps (up to 120 Gbps), 240W PD, 8K@60Hz, certified, USB-C male–male, white

StarTech Thunderbolt 5 cable, 0.5 m length, provides ultra-high performance connectivity between Thunderbolt 5-enabled devices. The certified cable delivers up to 80 Gbps bidirectional bandwidth with an optional Boost Mode that reallocates lanes to provide 120 Gbps transmit and 40 Gbps receive when display-intensive bandwidth is required. It supports DisplayPort 2.1 Alt Mode for up to 8K@60Hz (or 4K@240Hz with DSC), PCIe 4.0 connectivity for external GPUs and storage, and 240W USB Power Delivery for charging high-performance laptops. The compact, white USB-C male-to-male cable is backward compatible with Thunderbolt 4/3, USB4 and USB 3.2 hosts.

Advantages

The Thunderbolt 5 cable offers significantly increased bandwidth compared with Thunderbolt 4, enabling high-resolution video, fast data transfers and high-power charging over a single connection. Intel-certified performance ensures compatibility and predictable operation across supported devices. A durable halogen-free TPE outer jacket, braided shielding and nickel-plated connectors provide resistance to daily wear, reduced EMI and long insertion life.

Suitable for

• Connecting high-performance laptops (for example 16in MacBook Pro with M4 Pro/Max) to docks or monitors
• Driving one or two high-resolution displays up to 8K@60Hz for video editing and color-critical work
• External GPU enclosures, PCIe chassis, and high-speed external storage requiring PCIe 4.0 throughput
• Fast charging of compatible laptops and devices using 240W Power Delivery

• Color: White

How to use

Connect one USB-C end of the cable to a Thunderbolt 5 or compatible port on your laptop or host device and the other end to a Thunderbolt 5-enabled peripheral, dock, monitor or chassis. For display-intensive workflows, enable Boost Mode on supported hosts or devices if required to allocate asymmetric bandwidth for higher transmit throughput. Ensure both connected devices support the desired features (for example 240W PD, DisplayPort 2.1, or PCIe passthrough) to achieve full functionality.

Usage recommendations

Use the cable in environments where minimal EMI is required and avoid sharp bends beyond the tested bending radius. For consistent 240W charging and maximum video performance, use directly with certified Thunderbolt 5 hosts and peripherals; when connecting to older or lower-spec devices, expect the connection to fall back to the highest mutually supported mode (Thunderbolt 4/USB4/USB 3.2).
