Is It Risky to Use Computer Without UPS?
Sometimes due to various reasons, the voltage of the supplied electricity suddenly decreases or increases, if the effect of this change falls directly on the power supply of the computer, then there is a danger of some of its components being completely damaged, even burned. In order not to do so, the power supply unit has a "fail-safe", that is, it will disconnect on its own before anything else on the computer is damaged.
This fail-safe is not completely reliable, in some extreme cases, the power supply itself is wasted, or short-circuited and supplies excessive voltage.
UPS or Uninterruptible Power Supply, as it is called in its name, provides uninterrupted power. That is, whatever the voltage of the current, its battery will always supply a certain amount of voltage and current. As a result, there is no possibility of disturbance in the power supply unit.
Another advantage of UPS is that when the current suddenly goes out, the PC does not turn off directly, but gives you time to shut down manually, so there is no fear of losing unsaved work, data loss, or memory corruption.
