Most of us never really think about the power quality our systems are fed. We use simple power strips or surge protectors, and generally never give the issue another thought.. That is, until you have a power surge or blackout, and lose that important article or term paper you've been working on for the past 12 hours. However, power outages and surges are not the only concern facing computer users, as poor power sources (low quality wiring, old homes, etc) can also create problems with fluctuations, which can damage you hardware or corrupt your data.
