Certified 80 Gbps Thunderbolt 5 Cable

This 80 cm Thunderbolt 5 cable carries a certified bidirectional 80 Gbps data rate, delivers up to 240 W of power and drives an 8K display at 60 Hz. The male-to-male USB-C connectors use shielded 30/34 AWG coax wire for signal integrity. It is built for high-performance laptops such as a 16-inch MacBook Pro M4.

Suits Thunderbolt 5 hosts needing full bandwidth

Creators moving multi-stream 8K video or attaching PCIe 4.0 enclosures for GPUs, NICs or storage at 64 Gbps will use every lane. Buyers whose workflows stay at lower resolutions or lighter I/O loads will not use the headroom this cable provides. Systems limited to earlier Thunderbolt or USB-C speeds cannot unlock the certified performance.

80 Gbps certified Thunderbolt 5 bandwidth

The single specification that decides fit is the certified 80 Gbps bidirectional throughput. If the host, dock or device chain does not support Thunderbolt 5 at that rate, the cable will fall back to the lowest common denominator and the extra capacity goes unused.

Questions about this item

What USB Type-C clearance does the 80 cm male-to-male cable need at each port?

The 31.5 cm (2.6 ft) cable has USB Type-C male plugs on both ends, so each device needs a standard USB-C port opening with enough depth for the connector housing.

How do I connect this Thunderbolt 5 cable so the 80 Gbps link and 240 W power delivery activate?

Plug one male USB-C end into the host and the other into the peripheral; the cable is certified for Thunderbolt 5, so the 80 Gbps bidirectional speed and 240 W PD negotiate automatically — no driver or switch required.

Will the 30/34 AWG shielded coax conductors need replacement after heavy 64 Gbps PCIe 4.0 or 8K 60 Hz use?

The cable uses shielded 30/34 AWG coax wire rated for the certified 80 Gbps, 120 Gbps peak, 240 W PD and 8K 60 Hz video; it has no user-serviceable parts and requires no scheduled replacement.
