Protecting PCs With UPS Systems: A Short Guide

When it comes to protecting a computer, one can’t be too careful. Many assume that if the system gets plugged into a surge protector or power strip, their devices are safe from harm. Unfortunately, this isn’t the case. The computer power supply is a pivotal aspect one has to consider while maintaining their systems. This article will shed light on what a UPS is and how to purchase these devices today. 

What Is A UPS?

A UPS is an uninterruptible power supply. It’s a battery backup system that provides backup power to one’s computer during blackouts or electrical surges. A UPS can also be used with a generator or battery, so it is not necessarily tied to the primary electricity grid that powers one’s house or office. A UPS is not the same as a surge protector; the design is for more than just protecting computers against surges.

What Size UPS Should I Get?

The next step is to know the size of the UPS for one’s computer. The first thing to consider is the size of the UPS itself, which will depend on how much power the system consumes and how many devices connect to it. Once individuals have this information, they can begin with versatile online charts to help them choose an appropriate unit for their needs.

While it’s recommended that manufacturers provide their documentation about sizing requirements, some basic guidelines include the following:

  • Determine what type of UPS would best suit the needs based on maximum runtime in minutes or hours with no load on the battery.
  • Know whether or not any additional items are attached to the device (for example, if there is an LCD monitor).
  • Keep in mind that typical units get sized according to peak demand; they may not be able to handle surges.

Which Battery Type Is Best?

It depends on the needs of the user. There are many different types of batteries, such as lead-acid, lithium and NiCad. These battery types can be used for all UPS sizes (from small desktops to large rack-mount systems). Different battery types have significant advantages and disadvantages that are worth considering.

How To Test The UPS?

If one is not sure how to test a UPS, here’s a quick guide:

  • Connect the power strip that’s plugged into the UPS to another outlet.
  • Turn off non-essential devices (such as computer monitors or printers) connected to this new outlet.
  • Turn on the computer and check that it boots up correctly and no errors occur, then turn off the computer again.
  • Plug all of these devices back into the original outlet and turn them on one at a time until they all work correctly. 
  • If there are any problems, something may have been damaged during testing. Alternatively, there is an issue with the connection or outlets themselves! 
  • If everything works fine after testing, turn off all connected equipment except for the UPS itself and ensure it still powers down correctly when it gets disconnected from its charger/source of power!


This article gives a good idea of what a UPS is and how it can protect one’s computer. A computer power supply is one of the significant components of every system. As mentioned above, devices like a UPS protect one’s system from data loss and help individuals to prevent damage to their computers. It also keeps people safe from fluctuations. Thus, these devices are preferred highly today.
