What this cable does and who it suits

The ESTONE TJ-A323 is a USB4 cable with USB-C male connectors on both ends. It carries 40 Gbps data, 100 W power delivery and 8K 60 Hz video over a 6.6 ft braided run. It suits laptop users who need one cable for high-speed SSD enclosures, eGPU docks, dual 4K monitors and fast charging.

Practical limits of the USB4 Thunderbolt 4 interface

The cable reaches 40 Gbps only when both host and device support USB4 Gen 3×2 or Thunderbolt 4. With USB 3.2 Gen 2×2 or Thunderbolt 3 the link drops to 20 Gbps. Video output requires the host port to implement DisplayPort Alternate Mode; without it no external display will appear. Power delivery tops out at 100 W and needs a PD 3.1 EPR charger to reach 20 V 5 A.

Capacity headroom for storage video and charging

A 40 Gbps link saturates current NVMe enclosures and eGPU boxes, leaving headroom for future faster drives. Dual 4K 60 Hz or a single 8K 60 Hz stream fits comfortably; higher refresh rates at 4K or 8K exceed the bandwidth. The 100 W rating covers every USB-C laptop and tablet on the market today; devices that demand more than 100 W cannot be powered by this cable.

Questions about this item

Should I choose the 6.6 ft length or a shorter option for my desk setup?

The cable measures 6.6 ft, giving plenty of reach between a laptop and a dock or monitor without excess slack on a typical desk.

What does the 40 Gbps rating mean when I plug in an NVMe enclosure?

40 Gbps is the peak USB4 Gen 3x2 bandwidth, so an NVMe enclosure can saturate the link and deliver full PCIe 3.0 x4 or 4.0 x2 performance.

How does the USB4 Gen 3x2 interface limit real-world video and data?

USB4 Gen 3x2 caps at 40 Gbps, allowing one 8K@60Hz stream, dual 4K@60Hz displays, or full-speed NVMe transfers, provided the host and device both support the standard.
