USB4 cable for 8K display and 100W charging

The LUOM TJ-A323 is a USB4 Gen 3x2 cable with USB-C male connectors on both ends. It supports 40Gbps data transfer, 8K video at 60Hz and up to 100W Power Delivery for laptops and accessories. Buyers who need longer reach than 3.3 feet or passive Thunderbolt 4 certification should look elsewhere.

Check your host and device ports

Ensure both ends provide USB-C ports that support USB4 or Thunderbolt 3 for full 40Gbps bandwidth and 8K output. The cable also works with USB 3.2 Gen 2 at 20Gbps and USB 2.0, but video and maximum charging require the host to implement DisplayPort Alt Mode and PD 3.1 or PD 3.0 PPS. Without those features the cable falls back to lower speeds and power levels.

Cable replaces separate charge and video leads

A single 3.3-foot cable carries 100W charging, 40Gbps data and 8K@60Hz video simultaneously. This removes the need for a dedicated power brick cable and a separate display cable when docking a laptop or driving an eGPU enclosure. Dual 4K@60Hz setups require two cables, one per monitor.

Questions about this item

Does the LUOM TJ-A323 cable come with a power adapter or do I need to buy one separately?

The cable is supplied alone. To reach the stated 100 W (20 V / 5 A) you must provide a USB-C charger that supports PD 3.1 or PD 3.0 PPS.

Should I choose this 3.3 ft model or a longer one for my 8K monitor?

This listing is for the 3.3 ft length only. It supports 8K at 60 Hz and 40 Gbps bandwidth at this length; longer versions are not described in the data.

What does the 40 Gbps figure mean when I transfer a large video folder between two laptops?

The cable is rated for up to 40 Gbps (USB4 Gen 3×2). Real-world read speeds reach 2.8 GB/s and write speeds 2.1 GB/s, provided both ports support that generation.
