Thunderbolt 5 cable StarTech 1m (3ft), 80Gbps (up to 120Gbps), 240W PD, 8K@60Hz, USB-C male–male, white

StarTech Thunderbolt 5 cable, 1 m length, provides ultra-high performance connectivity for Thunderbolt 5-enabled devices. The cable supports up to 80 Gbps bidirectional bandwidth with an optional Boost Mode that permits up to 120 Gbps transmit and 40 Gbps receive for display-intensive workflows. It also supports DisplayPort 2.1 Alt Mode for up to 8K at 60 Hz video, PCIe 4.0 data lanes, and 240W Power Delivery for charging high-performance laptops. The cable is Intel Thunderbolt-certified and maintains backward compatibility with Thunderbolt 4/3, USB4 (40 Gbps) and USB 3.2 (10 Gbps) hosts.

Advantages

The cable delivers doubled bandwidth compared with Thunderbolt 4, enabling simultaneous high-speed data transfer, multi‑display output and high-wattage charging over a single USB‑C connection. Boost Mode reallocates lanes to prioritize transmit bandwidth for demanding display setups. Durable construction with a halogen-free TPE jacket, braided alloy shielding and nickel-plated connectors provides resistance to bending and frequent insertions, while Intel certification ensures predictable performance across compatible devices.

Suitable for

• Connecting high-performance laptops (for example 16in MacBook Pro with M4 Pro/Max) to docking stations or monitors
• Driving single or dual 8K 60Hz displays or high-refresh 4K displays with DSC and HDR
• High-bandwidth external GPU, NIC or PCIe storage enclosures
• Charging power-hungry laptops and devices with up to 240W Power Delivery
• Mixed environments requiring backward compatibility with Thunderbolt 4/3 and USB4 hosts

Key specifications

• Cable length: 1 m (3 ft)
• Bidirectional bandwidth: 80 Gbps (standard), up to 120 Gbps transmit / 40 Gbps receive in Boost Mode
• Video support: DisplayPort 2.1 Alt Mode — up to 8K @ 60 Hz (with DSC), 4K @ 240 Hz, HDR and 10-bit color support
• PCI Express support: PCIe 4.0 throughput (64 Gbps) for external GPUs, NICs and storage chassis
• Power Delivery: up to 240W (EPR)
• Connector type: USB-C male to USB-C male
• Outer jacket: halogen-free TPE with braided alloy shielding to reduce EMI
• Durability: nickel-plated connectors rated for 10,000+ insertions; jacket tested for 2,000 bending cycles
• Color: white

How to use

Connect one USB-C male end to a Thunderbolt 5-enabled host or compatible device and the other end to a Thunderbolt 5-enabled peripheral, monitor, dock or charger. For display-intensive workflows that require higher transmit bandwidth, enable host or device settings that support Thunderbolt 5 Boost Mode if available. Ensure both host and peripheral support the required features (DisplayPort 2.1 Alt Mode, PCIe 4.0, or 240W PD) to achieve the described video, data and charging capabilities.

Usage recommendations

Use certified Thunderbolt 5 ports and devices to guarantee full performance. For maximum video performance (dual 8K @ 60 Hz) and Boost Mode benefits, verify monitor and GPU compatibility and use the cable at its 1 m length to minimize signal loss. Avoid excessive sharp bends and maintain strain reliefs to prolong connector life.
