What this cable does

The Jansicotek TJ-A323 is a USB4 Gen 3x2 cable with USB C male-to-male connectors. It carries 40 Gbps data, up to 100 W PD 3.1 power and 8K@60Hz video in a single 3.3 ft black cable. It works with Thunderbolt 3 and Thunderbolt 4 hosts, docks, eGPU enclosures, NVMe SSD enclosures and USB-C monitors.

Check your ports and power first

Your host and peripheral must both have USB-C ports that support USB4 or Thunderbolt 3/4 to reach 40 Gbps and 8K@60Hz. The charger and device must both implement PD 3.1 EPR at 20 V/5 A for 100 W charging; otherwise the cable will negotiate a lower rate. The 3.3 ft length suits desktop setups; verify it reaches between your devices.

Suits high-speed docks and 8K displays

This cable fits users who need maximum throughput for NVMe storage, eGPU or dual 4K@60Hz monitors from one port. It is not for buyers who only need 10 Gbps data or 60 W charging — a cheaper USB 3.2 cable will do that. It is also not for setups requiring longer runs or legacy USB-A connectors.

Questions about this item

Does the TJ-A323 cable come with any adapters or must I buy a USB-C power brick separately?

The box contains only the USB-C to USB-C cable; a PD 3.1 charger capable of 100 W (20 V / 5 A) is sold separately.

Should I pick the 3.3 ft length or a longer version for a desktop docking station?

The 3.3 ft length is the only version offered for the TJ-A323 model.

Will the 40 Gbps rating actually move large NVMe files at that speed on my MacBook Pro 16?

Real-world throughput reaches 40 Gbps when both host and NVMe enclosure support USB4 Gen 3x2, cutting big-file transfers to seconds.
