Will a surge protector really reduce the chances of electrical damage to my PC?
YES. Surges and spikes are an increase in electrical line voltage, often caused by a sudden change or demand for more electricity, such as turning on a large appliance, garbage disposal, air conditioner, washer, dryer, etc.
- A surge typically measures less than 500V and lasts less than two seconds.
- A spike, by definition, is much shorter in duration - less than one-thousandth of a second (millisecond), but can measure into the thousands of volts.
Either type of disturbance can damage electronic equipment beyond practical repair. In addition to change in demand for electricity, bad weather (lightning) and everyday electric utility company switching and maintenance can produce damaging electrical surges on the power line.
When purchasing a surge protector for your PC there is a few things that you need to consider. You need to pay close attention to the Joule rating of the surge protector. We recommend that you purchase a surge protector with at least a 4000 Joule rating for protection against surges and spikes.
