Certified 40 Gbps link for Thunderbolt 3 hosts

This Intel-certified Thunderbolt 3 cable carries 40 Gbps of data, 100 W power delivery and dual 4K 60 Hz or single 5K 60 Hz video over a 0.5 m USB-C to USB-C run. It is built for users who need the full Thunderbolt 3 feature set in a short, reliable connection.

Not for longer runs or non-Thunderbolt USB-C ports

The half-metre length suits desk-side docks, portable SSDs or eGPU enclosures sitting next to the host. Builds that route cables behind monitors, across rooms or through cable chains need a longer certified cable. Devices that only support USB 3.2 or USB4 at 20 Gbps will not gain Thunderbolt bandwidth from this cable.

40 Gbps Thunderbolt 3 certification decides fit

Only a cable bearing Intel’s Thunderbolt 3 certification guarantees 40 Gbps PCIe and DisplayPort tunnelling plus 5 A / 100 W charging. If the host or peripheral lacks Thunderbolt 3 ports, the link falls back to USB speeds and the certified performance is unused.

Questions about this item

How do I install the TB340GUCMM50CM cable, and what step do people often get wrong?

Plug the USB-C connectors firmly into both Thunderbolt 3 ports until they click; the common mistake is not seating them fully, which drops the link to a lower speed.

What maintenance or replacement will the TB340GUCMM50CM cable need later?

No scheduled maintenance is required; replace the cable only if the connectors become loose, the jacket is damaged, or the link no longer negotiates 40 Gbps.

What limit appears first on the TB340GUCMM50CM cable during sustained use?

The 100 W / 5 A power delivery ceiling is reached before the 40 Gbps data rate saturates, so heavy charging while driving dual 4K@60 Hz displays hits the power limit first.
