APC Back-UPS BX750MI
Part numberBX750MI
The same part under other regional numbers: BX750MI-GR, BX750MI-FR
The short answer
Four outlets and a 410 W limit define the APC Back-UPS BX750MI, a 750 VA UPS for a mini PC owner who wants a desk machine to ride through a power cut. Its output on battery is not pure sine, so the machine's power supply decides whether it is a good match.
Specifications
The 750 VA and 410 W figures are the ones to watch: add up what you plug in and keep the total under 410 W. Four outlets cover a mini PC plus a few small devices. USB management means the UPS can be connected to the computer. The part number is BX750MI, useful when you match it against the maker's own page.

Which mini PCs it fits
A UPS suits a mini PC when the total load stays within its 410 W and the machine's power supply accepts what the UPS produces on battery. This one does not give a pure sine output. That is why the machines we can name all come with the same caveat. The GMKtec M8, the HP Z2 Mini G1a and the Lenovo ThinkCentre M70q Gen 5 get a simulated sine wave on battery, so check that each power supply accepts it.
Checked against every mini PC sold on amazon.co.uk, from the specifications we hold for each machine.

Before you buy
The main limit is the simulated sine wave on battery: for each of the three machines named above, check the power supply before you buy. Do not judge by the 750 VA figure alone, because 410 W is the real ceiling. Runtime on battery is not something we have confirmed, so read the maker's page for it.
Common questions
Does the BX750MI give a pure sine wave?
No. The BX750MI does not give a pure sine output, and on battery the named machines get a simulated sine wave, so check that your power supply accepts it.
How much can it power?
It is 750 VA and 410 W, with four outlets. Add up what you plug in and keep the total under the 410 W figure.
Can I connect it to my mini PC over USB?
Yes, it has USB management, so it can connect to the computer. The maker's page has the details of what that includes.
