ESTONE TJ-A323 USB4 cable 40Gbps 100W 6.6ft

The ESTONE TJ-A323 is a USB4 Gen 3x2 cable with USB-C male connectors on both ends. It delivers up to 40Gbps data transfer and supports 100W Power Delivery 3.1 charging. The 6.6ft nylon-braided cable handles 8K@60Hz video output and is backward compatible with Thunderbolt 3 and USB 3.2 devices.

Professionals needing 8K@60Hz or dual 4K@60Hz output

This cable suits users who require 40Gbps bandwidth for high-speed storage, eGPU docks, or 8K@60Hz single-display workflows. It also fits Thunderbolt 3 or 4 hosts needing 100W charging. Buyers whose devices lack DisplayPort Alternate Mode over USB-C cannot use the video function. Those needing only 10Gbps data or 60W charging will not benefit from the extra specification.

40Gbps USB4 Gen 3x2 data rate

The decisive specification is the 40Gbps USB4 Gen 3x2 transfer rate, which is twice the speed of standard USB-C Thunderbolt cables at 20Gbps. This bandwidth enables 8K@60Hz or dual 4K@60Hz display support and full Thunderbolt 3/4 peripheral performance. If the host or device tops out at 20Gbps, the cable will still work but the higher throughput will not be utilised.

Questions about this item

Which ESTONE TJ-A323 cable should I choose for 8K@60Hz and 100W charging?

The single 6.6 ft USB4 Gen 3x2 cable delivers 40 Gbps data, 8K@60Hz video and up to 100 W (20 V/5 A) power delivery, so one model covers both needs.

What does the 40 Gbps rating mean when I plug this into my laptop?

It enables full USB4 Gen 3x2 bandwidth for Thunderbolt 3/4 hosts, so large files and eGPU traffic move at the cable’s rated ceiling instead of falling back to 20 Gbps.

Is the USB-C connector limited to USB 3.2 or does it carry Thunderbolt 4?

The cable is certified for Thunderbolt 3 and 4, USB4 Gen 3x2 and backward compatible with USB 3.2, 3.1 and 2.0, so it caps at the host’s highest supported standard.
