LUOM TJ-A323 USB4 Cable 40Gbps 100W 8K@60Hz 6.6FT

This USB C to USB C cable supports USB4 Gen 3x2 for up to 40Gbps data transfer and 100W Power Delivery. It handles 8K video at 60Hz and works with Thunderbolt 3 devices. The bi-directional, reversible connectors suit laptops, phones, SSDs and monitors that use USB-C.

Practical limits of USB4 Gen 3x2

The cable reaches 40Gbps only when both host and peripheral support USB4 Gen 3x2; otherwise speeds fall back to the lowest common standard. Full 100W charging requires a PD 3.1 EPR charger and a device that accepts 20V/5A. Video at 8K@60Hz needs DisplayPort Alt Mode on both ends, and dual 4K@60Hz setups require two separate cables.

Installation and common issues

Plug the reversible USB-C ends into each device; no drivers are needed. The 6.6FT length may limit placement between desk and monitor. If charging stays below 100W, check that the power brick and device both support PD 3.1 EPR. Data speed drops sharply if either port is only USB 3.2 or Thunderbolt 3 without USB4 Gen 3x2.

Questions about this item

Should I pick the 6.6FT length or a shorter version for my desk setup?

The 6.6FT length gives you reach across a typical desk or to a wall outlet without excess slack. Shorter cables reduce clutter if your devices sit close together, while this length suits docks, monitors or laptops placed further apart.

What does the 40Gbps rating actually deliver when I copy files to an external SSD?

With USB4 Gen 3x2 devices you can see up to 2.8GB/s read and 2.1GB/s write, so a 2.5GB file moves in roughly one second. Real-world speed depends on the drive, controller and host port capabilities.

How does the USB4 Gen 3x2 interface limit charging and video on this cable?

The interface caps power at 100W (20V/5A) under PD 3.1 Extended Power Range and carries 8K@60Hz or dual 4K@60Hz video. It also maintains full 40Gbps bandwidth for data while charging and displaying simultaneously.
