Good.
I doubt I've had a brown-out, as
the computer in question is on a UPS which has plenty of spare battery.
Check the voltage at the UPS input with a good voltmeter. In the USA,
voltage should be 120 VAC. National Electrical Code tolerance is +/- 5%.
A good UPS should be able to accept dirty out-of-spec input and produce
clean, tight output.
Do not plug laser printers, photo copiers, or any other heavy loads into
the computer UPS. Those machines draw significant current in surges and
can clip the output of UPS's, causing the voltage to sag, lights to
flicker, and electronics to malfunction.
As for the power supply test, not having a power supply tester, I have
not done that.
Buy one. It will save your sanity.
