CalDigit Thunderbolt 4 Pro Cable, braided, 0.5 m
Part numberTBT4-P05BW-240
The short answer
Short and braided, CalDigit's TBT4-P05BW-240 is a 0.5 m cable for a mini PC owner whose machine has a USB4 or Thunderbolt port and who wants a compact link from it. It is a cable, not an adapter, so the port on your machine decides whether it is any use.
Specifications
At 0.5 m, this is a short cable, best for a device sitting right beside the mini PC. The part number is TBT4-P05BW-240 and the cable is braided. What you get depends on the port: on the USB4 ports of the ACEMAGIC AM08 Pro, ASUS NUC 14 Performance and Apple Mac Studio (M5 Max), the link runs at 40 Gbps, not 80.

Which mini PCs it fits
A cable like this needs a USB4 or Thunderbolt port on the mini PC. The ACEMAGIC AM08 Pro, the ASUS NUC 14 Performance and the Apple Mac Studio (M5 Max) fit with a caveat: the link runs at 40 Gbps on their USB4 port, not 80. The Lenovo ThinkCentre neo 50q Gen 5, MINISFORUM MS-A2 and ACEMAGIC AM06 Pro have no USB4 or Thunderbolt port, so it does not fit them. For the MINISFORUM AtomMan G1 Pro and MSI MAX Edge AI+, we have not confirmed the fit.
Checked against every mini PC sold on amazon.com, from the specifications we hold for each machine.

Before you buy
CalDigit does not state the standard, the bandwidth, how much power it carries or the video support, so check those before you count on it for charging or a display. On the three machines with a caveat, expect 40 Gbps, not 80. A machine without a USB4 or Thunderbolt port cannot use it.
Common questions
Will this cable work on a mini PC that only has ordinary USB-C?
It needs a USB4 or Thunderbolt port. The Lenovo ThinkCentre neo 50q Gen 5 and the MINISFORUM MS-A2 do not have one, so the cable does not fit them.
What speed will it run at?
CalDigit does not state the bandwidth. On the ACEMAGIC AM08 Pro, ASUS NUC 14 Performance and Apple Mac Studio (M5 Max), the link runs at 40 Gbps on the USB4 port, not 80.
