What this cable does and who needs it

The Jansicotek TJ-A323 is a USB4 cable certified by USB-IF for 40Gbps data, 100W power delivery and 8K video at 60Hz. It connects two USB-C devices with a 3.3 ft black male-to-male lead. Buyers who need a single cable for charging, display and fast file transfer between a laptop and a dock or monitor will use every feature.

Who this suits and who should look elsewhere

Creators moving large video libraries between high-speed enclosures and a MacBook or XPS will hit the 40Gbps ceiling. Users whose devices only support USB 3.2 Gen 2 or Thunderbolt 3 at 20Gbps will not reach the rated throughput. Anyone needing a longer run for a desk-to-screen setup should choose a different length.

The spec that decides fit

The cable carries the USB4 Gen 3x2 standard with a 40Gbps bandwidth rating, which determines whether your host, dock and peripheral can actually exchange data at that speed. If any link in the chain tops out at 20Gbps the transfer will fall back to the lower rate.

Questions about this item

Does the 3.3 ft cable ship with any adapters or power bricks, or is it just the USB C to USB C cable?

Only the USB C to USB C cable is included; no adapters or chargers are bundled.

The listing mentions USB4 Gen 3x2 and Thunderbolt 3 — which version should I pick for 40Gbps and 8K@60Hz?

This single model delivers up to 40Gbps bandwidth and 8K@60Hz video when used with a compatible Thunderbolt 3 or Thunderbolt 4 port.

In a real laptop-to-monitor setup, will the 40Gbps rating actually give me 8K@60Hz or dual 4K@60Hz?

Yes, the cable supports single 8K@60Hz or dual 4K@60Hz output, provided both host and display run Thunderbolt 3 or Thunderbolt 4.
