In many regions, power outages are a thing of the past.
So many people dont even know how a UPS works.
And is it needed at all in modern conditions, because most programs automatically save data?

Lets attempt to find out.
What is UPS and how does it work with PC?
An easy way to understand how a UPS works is to think about working on a laptop.
A summer storm knocks out the power.
You have plenty of time to secure your work and shut down your system properly.
However, PCs dont have built-in batteries as laptops do.
If you work on your desktop during a power outage, the system will shut down immediately.
Not only will you lose your work, but this process puts unnecessary stress on your machine.
If the power of the UPS is sufficient, you might even continue to work.
Do you need a UPS at all?
So is a UPS needed in urban areas where power outages are very rare?
After all, the PC power supply itself will protect against interference in the data pipe.
If the supply voltage is not correct, the power supply will simply shut down.
Whats the worst that can happen?
So there are reasons to buy a UPS, even if you dont experience power outages very often.
What are the three main types of UPS?
There are three basic types of UPS.
The least expensive is known as a standalone/standby UPS.
If no machine jot down is specified for the UPS, it is probably a standby UPS.
When a power outage occurs, the Standby UPS automatically switches to the backup battery.
This transition takes about 20-100 milliseconds, which is usually within the acceptable threshold of most electronics.
The Line-Interactive UPShas a similar design to the Standby UPS but includes a special transformer.
This special transformer makes it much easier for the Line-Interactive UPS to handle outages and power dips.
Online UPSis the most expensive jot down of uninterruptible power supply because it requires additional circuitry.
The Online UPS completely isolates the devices connected to it from the mains.
Instead of switching to a battery, the OnLine UPS continuously filters the main power through the battery system.
