CableDeconn USB4 cable 1m Thunderbolt 4 40Gbps 100W

This one metre cable carries USB4 data up to 40Gbps and delivers up to 100W of power over a single USB-C connection. It supports external displays at 5K resolution at 60Hz or 8K at 30Hz when the host and monitor both support DisplayPort Alternate Mode. The cable suits users who need high bandwidth for external SSDs, eGPU enclosures or high resolution monitors.

Sustained load behaviour

The cable maintains its 40Gbps signalling rate and 100W power delivery during extended transfers or continuous display output. Performance depends on the connected host controller and peripheral firmware supporting the full USB4 specification. Thermal limits of the attached devices will determine actual throughput over long sessions.

Upgrade context

This cable replaces older USB-C cables limited to 10Gbps or 20Gbps data rates and lower power delivery. The jump is worth it when moving large datasets to external storage, driving a 5K or 8K monitor, or powering a laptop and eGPU simultaneously. It does not suit buyers who only need basic charging or 1080p video output.

Questions about this item

Does the cable generate noticeable heat when delivering 100 W continuously?

The cable is rated for 20 V at 5 A, so it handles 100 W without overheating under normal use.

What must my laptop and monitor already support for 8K output?

Both devices need USB-C ports with DisplayPort Alternate Mode; the monitor must accept 8K at 30 Hz or 5K at 60 Hz.

Will this cable work with my older Thunderbolt 3 dock and external SSD?

Yes, it is compatible with Thunderbolt 3 and USB 3 devices, though speeds will fall back to the older standard's limits.
