UPS is an uninterruptible power supply (UPS) that helps protect your computer from sudden power surges. In the event of a power outage, the device takes over the entire load and makes it possible to calmly save all its work and turn off the computer in normal mode through the system functions, thereby protecting the power supply and the motherboard from burning.
Selection of power UPS
The correct UPS should be selected based on the power consumption of the equipment. The battery power should be 20-30% higher than that of your computer system. To select the optimal energy source, it is not necessary to calculate the power consumption of the system, power supply, video card, etc. It is enough to roughly estimate the performance of your machine.
So, for a standard computer with a conventional configuration (for example, with a dual-core processor and a 350 VA PSU), a UPS with a capacity of 1000 - 1500 VA is suitable. Such a device will be sufficient to provide uninterrupted power supply and protection against sudden power surges.
If you have a computer with a gaming configuration, you should select a more powerful UPS (from 1500 and above).
If you cannot determine the capacity of your equipment, visit the website of the UPS manufacturer and use the program or tool to select the appropriate model online. You only need to indicate the approximate configuration of your equipment.
UPS type
The simplest and most inexpensive will be a backup UPS, which operates mainly in the saving mode and in the event of a voltage surge will instantly switch to the built-in battery. This type will become a reliable protection for a regular computer and a standard electricity network.
However, if you are experiencing fairly frequent surges in your home network, you need to turn your attention to a line-interactive UPS with a voltage regulator. This power source will switch to battery much faster. The device has a long service life and a degree of protection against sudden changes.
The most serious protection against power surges is provided by online UPS, which operate in a constant mode and generate stable energy during the operation of the computer, providing constant power. This type of device is certainly effective, but also the most expensive.
Buying a UPS for your home online is usually unreasonable and in most cases it is better to save money and purchase a backup or line-interactive power supply.
The cost of a UPS can be determined by the battery life (battery size), capacity and the type of power supply.
When purchasing UPS, you should choose models that have software that will allow you to save running programs. In the event of a sudden shutdown, the device will reopen all running programs.
