Having just invested lots of money in a Mac Pro 5.1 I thought it'd make sense to supply it with as "clean" AC power as possible (eliminating spikes etc.). I know about so called "surge protectors" from APC and other companies, but do they really work? There's really no easy way to check if they actually do condition the power or not. Something else I've been thinking about is getting an UPS so I'll be allowed to save whatever I'm working on in case of a power outage (I've been using a laptop up to now so that hasn't been an issue) and I understand that they condition power even better than surge protectors, but there are so many to choose from with huge differences in cost. I see that APC sell a few that basically don't cost much more than some of the "high end" surge protector power strips (they actually look like oversized power strips), but according to discussion threads on the subject here I need to get a "Smart-UPS" model if using with the Mac Pro -and they're pretty costly! If the latter is correct I should probably just get a good surge protected power strip for now, then invest in a smart UPS later. Suggestions?
