Your computer or laptop may not always have a stable supply of electricity. An unexpected surge may occur, and the power supply may suddenly be cut off. This has a negative impact on the functioning of the computer, leads to breakage, and can affect data storage. To avoid this, an uninterruptible power supply (abbreviated as UPS) was invented. It provides the PC system unit and its monitor with stable power supply, and gives time for the PC to shut down correctly.
When choosing a device, you should pay attention to the following aspects::
- Power output;
- Device type;
- Number of connections.
The brand of equipment, its ability to configure, and maintainability are important.

How to choose an uninterruptible power supply for your computer
When choosing a device, you should focus on the power of the device, the duration of its Autonomous operation. Based on these parameters, you should carefully select the appropriate UPS.
You should pay attention to the type of computer UPS. There are only three of them:
- Line-interactive (or interactive);
- With double conversion;
- A backup one.
They will be discussed in more detail later.
If you choose bespereboynik online, you should not make a choice based on the posted photos, they can deceive. You should watch reviews from experts, preferably video reviews.
Very important: don’t overpay for unnecessary features that you won’t need.
There are other parameters that are very important in the selection process. They will be discussed separately. Let’s tell you about the most important ones.
By equipment capacity
Initially, you should find out what power the uninterruptible power supply is designed for. Why buy a device that is too powerful if the estimated total value of office equipment connected to UPS (uninterruptible power supply) will be much lower? In addition, you will have to pay extra for extra kilowatts.
Very important: keep in mind that the gaming computer consumes more KW.
So before buying UPS, you should carefully analyze and calculate the total power of the connected equipment. On the other hand, if the power of the office equipment used is underestimated and a UPS with insufficient parameters is purchased, the latter will not be able to fully perform its duties.
On all devices and equipment, the consumed kilowatts (rated power) are indicated. You should check this parameter on all devices that are planned to be connected and add them up. Uninterruptible power supplies usually indicate the output power, expressed in volts-amperes (VA), you should know it beforehand. The first indicator should be converted to the second one. You can do this using the formula:
PBX = Phnom/k, where Phnom is the rated power, and k is the power factor.
The last indicator is indicated in the technical specifications, it ranges from 0.1 to 1.
The output power of all connected appliances should be 25 to 30 percent less than that of the UPS.
The UPS power factor must not be less than that of the equipment used.
The duration of Autonomous work
The battery life of an uninterruptible power supply depends on the capacity of the battery used in it. The larger the capacity of the device, the longer it will be able to work when disconnected from the power supply. Not the last role is played by a correct calculation of power. The higher the last indicator for UPS, the less powerful the equipment used, the longer the offline mode will remain.
Most UPS systems are designed for Autonomous operation from 5 minutes to 10 minutes, and there is enough time to properly turn off the computer. There are devices that can last up to 12 hours of battery life. With such uninterruptible power supplies, you can not worry about power outages at all — a normal shutdown is limited to several hours. But these UPS are much more expensive than their “normal” counterparts.
You should decide whether to buy a similar model. Perhaps a regular device will do.
By other characteristics
Power, possible battery life — the most important characteristics when choosing a UPS, but there are others that are worth paying attention to.
First, you need to see the number of connectors at UPS. Every consumer should know in advance how many and what devices (if there is a continuous video surveillance system, it is necessary to take it into account) will be connected to the device. Some UPS systems are equipped with special connectors to protect telephone and data lines from power surges, which is important when using a telephone connection to the Internet. In General, the following connectors can be used in the UPS:
- Sockets that connect appliances to the battery;
- Sockets that connect UPS to the stabilizer without connecting to the battery;
- Connector for connecting an uninterruptible power supply to the power grid;
- Connector for connecting network and telephone lines;
- Connector for controlling the UPS from a computer;
- Connector for diagnostics and monitoring (USB, COM).
Not only do computers need protection from power surges, but extra power outlets can also be useful.
Secondly, an important function is the way the device is displayed. Inexpensive models are equipped with conventional LEDs. Green indicates the normal state of the device, while red indicates a breakdown. Expensive UPS systems are equipped with LCD displays, which display the most important information about the operation of the UPS.
Third, not the last factor is the manufacturing company. Each industry has its own leaders who produce equipment better than their competitors. The best uninterruptible power supplies are produced by the following companies: Ippon, Luxeon, Powerman, P-Com, APC, Mustek, CyberPower, Eaton, SVEN, 3Cott, Inelt, Nashi Energiya and Bastion.
All these characteristics must be taken into account when buying, so as not to be disappointed later.
As mentioned above, there are three types of uninterruptible power supply: redundant, interactive, and dual-conversion. For each case, one or another type of uninterruptible power supply is suitable. We’ll tell you more about their use and functions later.
This type of uninterruptible power supply will suit a consumer who rarely encounters power outages or power surges. A backup UPS is the best option for this case. Offline operation is limited to 5-10 minutes, which is enough to disconnect the computer from the network.
If there are frequent power outages and power surges, you should purchase an interactive UPS. They are more expensive than backup analogues, but their choice is cheaper than repairing office equipment after exposure to such incidents.
The price is higher than that of the previous type of device, largely due to the use of a more complex circuit. It allows you not to go offline during jumps, but equalizes the voltage thanks to the built-in transformer. The battery is turned on only during emergency situations, when it is not possible to achieve a normal, stable supply of electricity.
With double conversion
The most expensive sources are those with double conversion. Their purchase is justified when it comes to the uninterrupted operation of servers.
Their principle of operation is much more complex than that of the previously mentioned uninterruptible power supplies. The connected devices are powered both from the mains and from the UPS battery. Mains voltage is applied to the equipment filter, interruptions are smoothed out, and high-frequency interference is suppressed. Then the current is rectified using diodes. Then the rectified electricity is fed to the inverter, where it becomes variable again, and is fed to the devices that consume it.
It is not advisable to use such a UPS with a home computer.
