Thanks to all that have replied.
My main priority is to protect my Dell computer, router and digital interface from power interruptions. We do have a backup generator which takes more than 2 seconds to detect an outage and more time to transfer power..

I've only done a bit of research so far. I have a mass produced Chicony Corp 750W power supply in the Dell but the crucial unknown is its hold time.

This UPS from APC has more outlets than I need plus some other goodies. And it shows 900W and a transfer time between 6 and 10 milliseconds. But if the Chicony hold time is only 4ms (or anything less than 6ms) then it won't prevent a crash; if the specs are to be believed.

Has anyone experienced a computer crash when connected to any UPS?

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
