what to avoid


As with any electronic device, all UPSs are not created equal. Here’s what you want in your UPS, and what you should steer clear of.

  • Power: Use this online load calculator to determine the total electrical consumption of all the equipment you plan on connecting to your UPS. Then look for a UPS with an output watt capacity 25 percent higher than the number you calculated.
  • Runtime: How long do you want or need your computer to run after a power outage? Whether you just need a few minutes to power down safely, or you want to be able to keep working longer, this is an important feature to consider before purchasing a UPS. Keep in mind that the number of devices you plug into your UPS will also affect runtime, with more devices resulting in a shorter runtime.
  • Space-Saving Form: The two most common UPS forms are tower and rack-mount. As the name implies, tower models stand up on a desk, shelf or floor space. These are the most common UPSs for desktop computing and home workstations. Rack-mount models are made to be installed on the wall in a rack. They are more commonly used with servers and networking.
  • Software: It may be useful to buy a UPS that includes power management software. This gives you the added protection of software that will manage and monitor your UPS without requiring any action on your part. Therefore, should the power go out while you’re not home, the UPS’s software will save any open work and shut your computer down safely.
  • Stay Away From: To save on future costs as well, avoid UPS models with batteries that must be changed by a professional technician. User-replaceable batteries mean you can make the switch by yourself, which will save time and money.

There are also online calculation tools that help you find the ideal UPS and battery size based on an estimate of extra power you may need for future devices, your optimal equipment runtime after a power fail and the voltage system you use based on your country.
