What this cable is and who it is for

The Jansicotek TJ-A323 is a USB4 Gen 3x2 cable with USB C male to male connectors. It delivers 40 Gbps data transfer, 100 W power delivery and 8K video at 60 Hz. It suits users who need a single cable for high-speed SSD enclosures, eGPU docks, dual 4K monitors or fast laptop charging. It is not for buyers who want a longer reach than 6.6 ft or a cable rated above 100 W.

Thermals, noise and power draw in normal use

The cable carries up to 20 V at 5 A under PD 3.1 Extended Power Range, with a built-in E-marker chip that identifies the 5 A capability and adjusts current within spec. No active cooling or fan is present, so operation is silent. Power loss appears as mild warmth along the 6.6 ft length during sustained 100 W charging sessions.

The specification that decides fit

The decisive figure is the 40 Gbps USB4 Gen 3x2 bandwidth combined with 100 W PD 3.1 support. If your host, dock or device requires Thunderbolt 3 or Thunderbolt 4 certified cables, this cable meets the electrical and signalling requirements for those uses. If your workflow needs only 20 Gbps or 60 W, a lower-spec cable will also work.

Questions about this item

How do I connect this cable for 40 Gbps data and 100 W charging?

Plug the USB‑C male ends into two USB‑C ports that both support USB4 Gen 3×2 and PD 3.1 EPR; the built‑in E‑marker chip then negotiates 20 V / 5 A automatically.

When should I replace this cable?

Replace it if the connectors become loose, the sheath frays, or the cable no longer negotiates 100 W or 40 Gbps with known‑good devices.

What limits 8K 60 Hz output during long sessions?

The 6.6 ft length and 40 Gbps bandwidth cap sustained 8K 60 Hz; thermal throttling in the host or display usually appears before the cable itself fails.
