The short answer
Keeping a mini PC running through a short power cut is the job of the Eaton 5E Gen2 900 USB IEC (5E900UI), a UPS with 900 VA and 480 W of capacity. It has four outlets and USB management for connecting to a computer.

Specifications
The 900 VA and 480 W figures cap everything on the unit together, so add up the draw of the mini PC, the monitor and anything else before you plug in. Four outlets means four connections at most. USB management means the UPS can be connected to a computer over USB. Eaton's own page has the full specifications.

Which mini PCs it fits
A UPS has no slot or port to match, so fit comes down to load: everything you plug in has to stay within 900 VA and 480 W together.
The GMKtec NucBox G3 fits, because its specs and the UPS's line up. So do the HP Z2 Mini G1a, the Lenovo ThinkCentre M70q Gen 5 and the MINISFORUM AI X1 Pro, each for the same reason.
Checked against every mini PC sold on amazon.co.uk, from the specifications we hold for each machine.

Before you buy
Eaton does not state whether the output is a pure sine wave. A matching fit means the machine's specs line up, not that your whole desk stays under the limit, so check your own total draw against 480 W before buying.
Common questions
How many devices can I plug into it?
It has 4 outlets, so up to four devices can connect, as long as their combined draw stays within 480 W and 900 VA. Add up the draw of each device first.
Is the output a pure sine wave?
Eaton does not state whether the output is a pure sine wave, so we have not confirmed it. Check the maker's own product page before relying on it for sensitive gear.
Does it connect to a mini PC over USB?
Yes, the unit has USB management, so it can connect to a computer over USB. The Lenovo ThinkCentre M70q Gen 5 is one of the machines it fits.
