UPS - Uninterrupted Power Supply

Updated on February 9, 2011

Protect your Computer and Expensive Electronic Equipment

We all know that when a storm hits our neighborhood we should unplug sensitive equipment from the electric grid! Just in case lightning hits power lines and fries our electric equipment! I have to confess that I have once witnessed an electrical plug, were the fridge was connected, explode from the wall due to lightning! The fridge became toast and I had to get a new one!

Lightning is not the only thing you should worry about, the electricity supplied to your home is alternating current (AC). As all electricity, no matter where you live in this world, whether you have 110v (like in North America) or 220v (Europe) there are always spikes and lows in the grid that can harm your electric equipment and the best way to protect them is with a UPS.

A UPS (Uninterrupted Power Supply) is basically a battery that is continually being fed with electricity and at the same time monitors the current for spikes and lows and feeds your equipment the exact and continuously the correct voltage!


  • The UPS is plugged to the wall socket and you plug your PC to the UPS!

A UPS as well, warns you, with an audible alarm of power failure! Depending on the model of the UPS, some give you anywhere from 5 minutes to 15 minutes of time so you can save your work and shut down the computer properly!

  • To anyone with sensitive information in their computer a UPS nowadays is a must! We spend more and more time in front of the screen and to most of us our lives are basically stored in a hard disk! Now image the cost of having that information retrieved by a professional just because your computer finally fried due to spikes!

  • A UPS is an investment that will pay for itself in no time. The first one I had (a 500amp APC-American Power Corporation) lasted me 16 years until the battery lost the capacity to retain the charge.

A UPS comes in many shapes, sizes and capacities, even some manufacturers offer up to a $75,000 equipment protection policy in case the UPS falters while still in warranty!

  • A 350amp UPS could be enough just for a single computer, but of you are thinking of plugging in more than one device then 500amp or even an 800amp should do the trick!

It´s a small investment that protects your computer and expensive electric equipment!

The price is relatively cheap; a UPS starts at only 30 bucks!
