Before you do that, how about lugging in an old UNIX workstation of some sort?

They usually survive power blips and if configured correctly will even syslog
the event - I've seen "temporary power failure" or something similar for
a brownout that made all the PC-class hardware in the building reboot.

Or put a surge protector in, stick a table lamp on the circuit to load it,
and wait to see if the surge protector trips. Worse you're going to get
is a blown bulb in the lamp, I'd've thought.
