I only have that experience with low quality UPS.

Also, a good UPS does more than just keep the machine running when power
goes out. A big bonus is clean power. My equipment on the T2000 all had
significantly fewer issues than equipment not on it even when I did not
lose power.

Of course, this is eastern Virginia, where we never go more than 1-3
months without power glitches or outright blackouts, and extreme
electrical storms, nor'easters, and hurricanes are several times a year
events.
