Protection Against Power Problems

There are several levels of protection that you can apply to help protect your computer system--and your data--from loss or damage as a result of these power problems. Not surprisingly, the more you spend, in general, the better protection you get, with costs ranging from near zero to several hundred dollars or even more.

This section takes a look at the conventional means that are used to protect against power problems. In addition, using backup power such as an uninterruptible power supply (a UPS) will allow you to avoid most power problems plus giving you protection against outright power service interruptions. UPSes are covered in this section.

Tip: An important form of protection against lightning strikes that most people ignore is to simply unplug the PC when a storm threatens. This is by far the best protection during a storm, yet few people think to do it.
