Sam,

I see that several posters have discussed the damage that can be caused by power outages, power surges and lighting but no one has mentioned the damage that can be cause by power brownouts. I noticed that the lights in my house would go dim from time to time but they didn't seem to effect my computer. After I did some research I realized that these brownouts could cause damage to my computer.

Brownout Definition: A reduction in the mains voltage without a complete loss of power. A brownout is a steady lower voltage state. An example of a brownout happens during peak electrical demands in the summer, when utilities can't always meet the requirements and must lower the voltage to limit maximum power. When this happens, computer systems can experience data corruption, data loss and premature hardware failure.

After I installed a UPS, I noticed that the UPS would occasionally kick when these voltage drops would occur. It gave me a good feeling knowing that my computer was protected from damage by my UPS. Over time these brownouts would have shortened the life of my computer.

Personally I would never be without a UPS but it really depend on your situation and requirements. If all you use your computer for is email and games or you live in a building that has a backup generator and a power management system, then a UPS is probably not necessary. But for many people that rely on their computer for making a living, a UPS is practically a necessity.
