I analyzed a couple of different accurate-sine UPSes, which have been each pretty high-priced. Their output looks like this:
The CyberPower CP1500AVRLCD3 is on a par with our upgrade choose in many respects, and it done a little better in our run-time tests, maintaining a 300 W load managing for 21.
Regarding interface, a USB interface is conventional. You will see a USB interface for every UPS on this list, except a product that also offers serial connectivity.
As for the dilemma of whether or not any of your products in the SOHO rack cares about the standard of the UPS electrical power output, that depends on the design of every ingredient's electricity offer.
For anyone who is on Home windows this would possibly not be A great deal problem, but when you are employing macOS or Linux you do not need to find out put up-invest in that all the interesting software bells and whistles you observed within the advert duplicate are Windows-only.

(Observe: Ethernet ports on UPS models this site are notoriously flaky, so It can be generally most effective to isolate the supply of the Ethernet, e.g. the router or community change, with its own defense in place of stressing about isolating each and every particular person cable prior to it reaches a computer or machine.)
