Belkin Connect Thunderbolt 5 Dock

Part numberINC031ttSGY

The same part under other regional numbers: INC031kqSGY

The short answer

Part number INC031ttSGY is what sets this dock apart from its sibling, which is sold under INC031kqSGY. It is a docking station with a Thunderbolt 5 host connection and 140 W of power delivery, for a mini PC owner who wants Ethernet, card readers and extra USB ports behind one cable.

The only difference from the Belkin Connect Thunderbolt 5 Dock is the part number: INC031ttSGY here, INC031kqSGY there. Every other specification is the same, so the fit is too. Pick this one if INC031ttSGY is the number you need.

Which mini PCs it fits

The dock connects over Thunderbolt 5, so the machine needs a USB4 or Thunderbolt port. The HP Z2 Mini G1a and MINISFORUM AI X1 Pro fit with a caveat: they run the dock at 40 Gbps on their USB4 port, not 80. The GMKtec NucBox G9 has no USB4 or Thunderbolt port, so it does not fit. The fit is not confirmed for the ASUS ROG NUC 15.

Checked against every mini PC sold on amazon.com, from the specifications we hold for each machine.
