Most PC users understand that a power surge, blackout, or other sudden loss of electricity has the capacity to seriously hurt your computer.
But exactly what one should do to protect against it gets a little fuzzier. The two most common means of protection are a standard surge protector, sometimes (wrongly) called a power strip, or an uninterruptible power supply, usually shortened to UPS. (No connection with the delivery guys in the brown shorts.)
Which one is right for your computer setup? That depends on exactly what you’re doing, and how much protection you want.
