Yes, of course.  Obviously the brownout resistance rests exclusively with
the unix pc power supply and the reserve power accumulated in the caps.
The high pitch noise that occurred during the brownout periods probably
just means that the switching circuits had to work extra hard to maintain
the output voltage.  Any power supply experts out there care to explain in
detail this phenomenon?
