You can protect your systems against damage from power surges by always using a surge protector, but it’s important to be aware that most cheap surge protectors will survive only a single surge and need to be replaced afterward. If you have a power outage, you may experience a surge when the electricity comes back on. Something as simple as someone turning on an appliance that’s plugged into the same circuit (especially a high voltage one such as a hair dryer, electric heater, or air conditioner) can cause a surge, or a surge may be caused by a tree limb touching a power line.

You may think your systems are in danger only during an electrical storm, but anything that interrupts the electrical circuit and then starts the current back again can fry your components. Here’s one that actually can physically destroy your computer equipment, as well as the data it holds.
