Why you need a UPS for your computer
UPS stands for uninterruptible power supply. So, an uninterruptible power supply for a computer ensures the functioning of the load during power surges. And in the event of a power outage, it provides uninterrupted operation of all included equipment. There are budget options with traditional protection and a short duration of work, but this time is enough for the correct completion of work.

It is worth noting the advantages of a UPS for the home:
- Protecting your computer from damage in case of unexpected disconnection from the network. In this case, you can safely close all open files and properly turn off the equipment.
- Protection against voltage surge.
- With a battery, the technician can work even when disconnected.
- The required voltage level is provided even without additional devices.
- High or too low voltage protection.
- Ability to switch to backup power.
The scheme of operation of uninterruptible equipment is simple: in a normal situation, the load is fed from the mains, and if the voltage disappears, it switches to battery mode.
Some models are equipped with an input and output voltage stabilization function. UPS models have a dedicated printer port.
Uninterrupted system with battery
The main types of UPS for computers
There are certain types of uninterruptible power supplies for the home. By the type of action, the equipment is divided into two types: off-line (offline) in the line (online). There are also models with a built-in stabilizer.
Let's consider all the options.
There are different types of sources
Standby (Back-UPS)
The offline PC UPS does not interact with the line while it is energized. But when it falls to the niche of the critical indicator, the device is connected to work with a battery. The supply voltage comes from a special storage device. Moreover, this transition is very fast. This option is of the reserve type.
The advantages of this system include low cost. Among the shortcomings, it is worth noting the long switching time to power from the drive.It is recommended to use such uninterruptible power supplies with a normal external network - 220 V. Devices are relevant in case of a short-term voltage failure.
Reserve type model
Line-interactive (Smart-UPS)
Linear interactive UPS for a private home is a lot like a backup option. But in this case, the device is supplemented with an external voltage stabilizer. Such an autotransformer provides a normal power supply. Uninterruptible power supplies of this type are distinguished by a long service life and higher power than those of a backup type.
Such models also have certain disadvantages, for example, the lack of frequency stabilization during normal operation and the penetration of electromagnetic and radio frequency interference from the external network.Such an uninterruptible power supply for the home is used to protect computer equipment from frequent power outages and unstable voltage.
Line-interactive option
Double conversion UPS (On-Line)
The most reliable option is uninterruptible power supply with double conversion of electricity. It provides a high level of power quality. The device is always connected to the line. If voltage is present, it is converted into direct current, which is used to recharge the batteries.
Feature of work in double conversion of input voltage.In this case, the battery for the UPS is constantly connected between the inverter and the rectifier.The advantage of an uninterruptible power supply is reliability of operation and quality of voltage. The disadvantages include the complexity of the circuit.
Perfect double conversion models
Main technical parameters of uninterruptible power supply for computer
If you do not know how to choose an uninterruptible power supply for your computer, then you need to study the important parameters that should be considered. The location of the device is also an important point. The vertical arrangement is used for desktop equipment. Rack mounting is also possible.
Technical characteristics on the example of a specific manufacturer
Power
When choosing an uninterruptible power supply for your home in case of a power outage, you need to make sure that the device can handle the load of the connected device. The power indicator of the uninterruptible device should be 20-25% more than the power of the computer. To correctly calculate the required performance, add the values of all connected devices.
UPS capacity depends on the parameter of a particular computer
Battery life
It takes no more than 5 minutes to save all open documents. With this parameter, you can buy a fairly high-quality device at an affordable price.The duration of operation without power is determined by the size and power of the battery.
Battery life of devices of different series
Number of connectors
When choosing an option, pay attention to the coincidence of the outlets at the output of the uninterruptible power supply device for the computer and equipment.If network adapters or telephony will be connected to the equipment, then it is important to have additional RJ-11 and RJ-45 connectors.Modern models are equipped with USB and RS-232, which help to establish control from a computer.
Each model may have a specific set of connectors
Software
Equipping the device with software is also important. In many models, protection algorithms are provided at the software level.The advantage of this system is that files are saved even if the user is not at the computer.Some models are equipped with connectors for connecting peripheral devices.
All the necessary indicators of the system are shown on the display
Controls
Convenience of control is also an important parameter. Some devices are equipped with built-in displays that show all the parameters of the system - power and voltage. Data can be displayed using special software immediately on the PC monitor.

How to choose the right UPS for your computer: recommendations
When buying a computer, in addition to high performance, you should pay attention to stability.
When choosing a suitable model, it is necessary not only to take into account the technical characteristics, but also various additions:
- short-circuit protection is available in almost all models. The function helps to prevent breakdowns associated with a short circuit of the device;
- electronic display helps to monitor operating parameters - overload, voltage and state of charge;
- the presence of all kinds of connectors to connect a modem, printer or fax;
- the cold start option allows you to turn on the UPS even if there is no voltage at the input;
- forced cooling system.
It is worth taking care of a quick battery replacement. It lasts for 1-2 years, and then becomes useless, since it cannot provide autonomous operation. In this case, the rest of the components can still be used. If it is possible to replace the battery, then you can use the device for many more years.
When choosing an option, you need to take into account the characteristics and capabilities of the equipment
How to choose a UPS for a computer by power
Determine the technical indicators of the computer, as well as decide on additional equipment. Next, you should calculate the total power. But keep in mind that the power indicator of the equipment is indicated in watts, and uninterruptible power supplies in volt-amperes.
A typical office PC with monitor, printer and speakers has an average of 500 watts. In voltapmers it will be 700 VA. The total power value is 800 W, and 1120 VA in volt-amperes.
Power is selected taking into account all connected equipment
Selection by connection type
Uninterruptible power supplies do not have standard sockets... They are equipped with special connectors for cables.In some models, the power also allows you to connect a monitor to an uninterruptible device. The fewer devices are connected, the longer the UPS will be able to work during a power outage.Turn on the computer to make sure the unit is working properly. Then install the software and configure the settings to make it work.
To understand the connection, you need to study the instructions
Selectable by input voltage range
The input voltage range defines the acceptable utility voltage that the UPS can maintain without switching to battery power. If you do not know how to choose an uninterruptible power supply, then this parameter is worth paying attention to. Battery life depends on it.
