About Us Show Notes Archive Beware the Power Spike Printer-friendly format Email this story Always use a surge protector. One of the biggest threats to a computer is a poor power supply. The supply doesn't yield a steady stream of electricity.
Power spikes run rampant over the power lines and literally fry the components of the computer.
A surge protector prevents those power spikes from reaching your computer and can save you thousands of dollars of damage. A good surge protector will also have a plug for your modem line. Power spikes over telephone lines are more common than electrical power surges. To use this feature, plug the telephone cable connected to your modem into the output port of the surge protector. Then, plug the surge protector into the wall outlet.
