I am in South Africa 220V power, with constant power outages I have purchased a small generator 2500 Watts just to run computers. &nbsp;I have a 650VA UPS &amp;&nbsp;a 1000VA UPS the manual says they use 390W and 600W respectively. &nbsp;I just want to confirm that they will infact draw 390W and 600W when powered by a generator as this will influence what equipment I run off my generator.

I am in South Africa 220V power, with constant power outages I have purchased a small generator 2500 Watts just to run computers.  I have a 650VA UPS & a 1000VA UPS the manual says they use 390W and 600W respectively.  I just want to confirm that they will infact draw 390W and 600W when powered by a generator as this will influence what equipment I run off my generator.

How many watts does a UPS draw when powering from a generator
