How to use the UPS to find out the power consumed by the computer?

Question

Uninterruptable power source

There is a Powercom BNT-800AP PSU with a USB interface, the Upsmon Plus program is installed on the computer, and it displays the degree of UPS loading in percent:

Question - how to convert these percentages into watts? Why take them from?

Answer 1

The most correct option is current clamps, in addition, there are fancy sockets that give off power consumption via smnp and there are parrots in the UPS, although if you think about it, you can look in the documentation, most likely there is an api

Answer 2

I looked at a review of a similar UPS, with 1000 W of maximum power and 130 W of load, it showed 13%. It looks like the percentage of the maximum power, in your case, multiply by 800.
And so, I would recommend the simplest power meter for 5 bucks with Ali, which is inserted between the plug and the socket
