What are the advantages of UPS - Uninterruptible Power Supply?

Answer 1

Answer

The primary advantage to a UPS is that in cases of sudden power loss the UPS will continue to power the computer system long enough for you to save your work.

Additionally, in environments which have problems with "dirty power"... meaning the electrical supply may have sudden spikes or dips such as in an older building or neighborhood the UPS offers a great deal more protection than a standard surge suppressor would.

In a new technology of UPS system the manufacturers offer lots of features including the surge suppression built-in device, hot-swap power module and battery module replacements. Additional backup time and run time calculation during power failure has great advantage for the end users to know the approximate time left for them to save their data before it completely shuts down (if the absence of utility power is too long and beyond the capacity of the UPS to operate).

Answer 2

The main one is that your computer won't reboot suddenly, causing data loss or (possibly) damage.
