I am looking for a new UPS for my machine. I'm not in the US so I don't have my pick of what online has, just what's available locally. I was looking at this one:
The overall reviews are good, but one review mentions that it's a risky choice for newer machines and was published in 2011:
It mentions that newer machines need a pure sine wave. My PSU is this one:
How can I find out if my PSU needs pure sine wave, if it would work properly with this UPS? Also, do UPSes give the approximated sine wave all the time or only when on battery? Will a PSU that needs pure sine wave not work at all on an approximated sine wave, or work and get damaged?
