What this cable is and who needs it

A 50 cm USB-C to USB-C cable rated for 10 Gbps data and up to 100 W Power Delivery 3.0. It carries DisplayPort 1.4 Alt Mode video up to 8K at 30 Hz and is Thunderbolt 3 compatible. The 24-pin gold-plated connectors suit docks, enclosures and laptops that require a secure side-locking connection.

Installation and common issues

Each end has an M2 screw 1.2 in long that threads into side-locking ports on compatible docks such as the StarTech DK31C3HDPD. The screws are removable for standard USB-C ports on drives or laptops. The 32 AWG conductors with aluminium-Mylar foil and 85 % braid shielding resist EMI. The TPE jacket survives 10000 insertions and 4000 bends, so repeated mating is reliable.

Behaviour under sustained load

The cable maintains 10 Gbps throughput and 100 W charging continuously thanks to the heavy shielding and gold contacts. Heat rise stays low during long file transfers or extended display sessions at 8K 30 Hz. Thunderbolt 3 signalling remains stable over the full 0.5 m length without the signal drop-offs seen on longer unshielded leads.

Questions about this item

How can I confirm the cable is delivering 10 Gbps after connecting it?

Check the host system's USB controller details or run a drive benchmark; a 10 Gbps link will report USB 3.2 Gen 2 x1 or 10 Gbit/s in the device properties.

What comes with the cable and do I need to buy screws separately?

The 50 cm cable includes two integrated M2 side-locking screws (1.2" long) that are removable; no extra hardware is required for docks or enclosures with side-locking ports.

Should I choose this 50 cm length or a longer version for a Thunderbolt 3 dock?

Pick the 50 cm cable when the dock sits right next to the laptop; longer lengths are only needed if the dock must be placed farther away.
