Hmm, well I live in southern California, umm typicaly power is steady @ 117VAC @ 60Hz, however our governor has made some bad contracts and has chosen not to approve new power plants. Every so often now we may have rotating blackouts in summer. I only have a power strip type. power has only been lost once with computer on, I switched off my Miggy right then to make sure if it came on "dirty" I was less likely to blow something.
So far , so good.
