The best uninterruptible power supplies (UPS) 4 kW (4000 W) 2021 according to customer reviews: which uninterruptible power supplies (UPS) are better to buy, how to choose the right one, price comparison

Failure of the power grid is a fairly common problem not only in remote regions, but also in small towns. A power outage occurs suddenly, so it is impossible to prepare for it, especially since in some cases such a phenomenon can have catastrophic consequences. An excellent example is a desktop computer, whose shutdown will cause the loss of unsaved files and unstable operation. For stand-alone devices, this problem does not exist, so you don’t have to worry about their safety, and to solve this issue with a PC, you need to purchase an inexpensive but effective device. Therefore, the reaction of the YaNashla website has prepared for you a rating of the best uninterruptible power supplies for a computer for 2021.

Consequences of incorrect shutdown

A certain percentage of users seriously believe that the computer is completely protected from power surges or sudden outages. This is partly true, if such a situation occurs once every six months or a year, then yes, the PC will survive it. But it’s another matter if the technology constantly faces this problem. No basic protection will be a panacea here.

The first thing that is important for such users to remember is that a computer is a complex technical device. It contains millions of important elements that interact with each other, which is necessary for the correct execution of tasks.

For example, the central processor almost always interacts with RAM and ROM. Thanks to this, the calculations required for specific tasks are carried out quickly. Thus, when listening to a piece of music, the CPU converts the digital signal into analog so that the user can relax and immerse himself in the joy of the violin or the wisdom of the piano. Even with the usual movement of the cursor on the table, the processor performs the necessary calculations, what can we say about movies, surfing the Internet or when spending time in computer games.

But this does not mean that if a person does not listen to music, does not launch an application, does not open a browser and does not have a single window on the desktop, that the processor is resting at this time. Yes, it is less busy, but the calculation occurs constantly and in some cases it is more important. The CPU sends signals to RAM every second, and the RAM responds. And if at this moment there is a sudden blackout, then the information will not have time to be saved, and this can lead to the most unusual malfunctions.

Variety of UPS

Over the past 10 years, the uninterruptible power supply market has made great progress. Maybe not every year, but manufacturers improve their models. So they try to improve the characteristics and lower the price tag so that the product wins 90% of the shelves. Despite thousands of options, ingenious designs, differences in voltage range and other parameters, uninterruptible power supplies come in three groups:

Reserve. The main function of such models is to connect internal batteries in the event of an unexpected power outage and the subsequent resumption of “home” power after solving the problems. Such UPSs do not have sufficient power and are often designed to quickly save data and properly shut down the computer. It will not be able to function fully without electricity. The design is ordinary, the additional functions are luxurious. The main disadvantage of such UPSs is that there is no voltage stabilizer, but more than half of the buyers know about this, so they buy them when they are sure that they are not in danger.
Interactive. Uninterruptible power supply systems of this type belong to the middle class category. They have a voltage stabilizer, so sudden drops or shutdowns are not a problem for them. The PC is always supplied with stable power, which increases the life of the elements and extends the average service life. In the event of an excessive voltage drop or a complete network shutdown, power will be supplied from the built-in batteries. Such uninterruptible power supplies are common among most buyers, as they have a reasonable price tag and additional charges. possibilities.
With double conversion. This type is only used for expensive devices or servers. It is difficult to find it in everyday life, but in large enterprises the use of such an uninterruptible power supply is mandatory. Only he is able to provide equipment with complete protection from negative influences. The principle of operation is simple: the supplied alternating current from a standard network is rectified and converted into direct current, after which it is supplied to the output of the device, where the reverse process occurs. Accordingly, the cost of such UPS exceeds 20,000 rubles. Therefore, a rare user will want to invest in a personal computer.

It is important to remember that some premium power supplies are equipped with modules that provide continuous connection between input and output. This allows you to reduce power costs during power outages.

Selecting a UPS for a PC

When buying an uninterruptible power supply, it is important to pay almost all your attention not only to the manufacturer, but also to the technical characteristics. It is better if a person considers both options at once. After all, in the 21st century, write in those. Almost anything can be done in the parameters, but only an experienced specialist can check it. Also, we must not forget about the capabilities of the computer itself and build only on this. Then the protection will be good, and the risk of defeat is minimal. According to the main selection criteria, the following parameters are distinguished: power, operating time when the power is off, number of connectors, the presence of special software, light indication, control method.

What to look for when choosing by power

This is the main parameter when choosing not only an uninterruptible power supply for a computer, but also for almost any equipment. Its importance comes first, only then is the operating time, etc., considered. The right choice is if the power of the computer is lower than that of the UPS. Otherwise, an overload will occur with further shutdown, and the purchased device will not be able to implement primary functions. For a successful purchase, it is important to purchase a device with a power that will be 30% higher than the connected equipment along with additional equipment. Only then will the user be confident in the correct operation of protection against power surges or power outages.

So, the acceptable power value for a standard office or simple computer is 300-500 VA. Such uninterruptible power supplies will fit perfectly into the work and will protect the connected equipment until the expiration date. However, some users connect a video card that consumes 250 W, plus the rest of the peripherals and a recommended unit of 500 VA, you can put it on a shelf or give it to the office, because in this case you will need a device with a power of 800 VA or more. Only he is able to cope with the entire load that the system will produce when the lights are turned off, and backup power supplies disappear immediately, because there are practically no representatives capable of protecting the PC.

If a person has difficulty calculating electrical energy, then the best option is to seek help from a specialist rather than taking it at random. Alternatively, some sites offer online energy calculations and suggest a specific model based on the results.

Select by operating time

The second important parameter is the duration of operation during an unplanned power outage. This value must be looked at in the technical characteristics of the purchased equipment. The indicator depends on the capacity of the batteries, which are located inside the case. For standard models, the working time period is from 10 to 15 minutes, this is completely enough to quickly save all files, stop the current session and immediately turn off the computer. However, if the user needs a longer period, then online stores provide him with this opportunity. So, by going to the website, you can filter uninterruptible power supplies to the required model. In addition, the duration of operation when the light is off is increased by connecting additional batteries through the appropriate connector.

Most often, companies involved in the production of UPS indicate battery life taking into account the maximum load, i.e. when using all power. However, not every company will agree that this is a true indicator, since it is often rounded to a value that is more pleasant for the person. You can also find this parameter on the official websites of manufacturers and correctly calculate the work for a specific situation, which is more convenient than coming to the store and not parting with a calculator.

Buying an uninterruptible power supply thinking that the battery life depends on the power is wrong. Only the load size and battery capacity can answer this question.

Select by Accessibility

The technical characteristics discussed above are the main ones, and only focusing on them, a reliable device is selected. It is important to consider them first and only then proceed to additional features aimed at simplifying management.

Software. Most modern UPS systems for PCs come with a special disk. It contains a utility that is installed on the computer and keeps operation statistics. The received information is stored in memory. This is a useful feature, the presence of which will simplify the operation of the device.
Number of connectors. The simplest models are equipped with a single connector for connecting a PC, and this is not very practical in some cases. Because a PC always includes peripheral devices that cannot be used if the power supply is not working correctly. To avoid getting into such trouble, it is important to know how many devices will be connected and be sure to calculate the total power. Then a choice is made in favor of a specific model.
Indication and control methods. The best option is an uninterruptible power supply with light and sound indication of operating modes. In addition, most models are equipped with an informative display that notifies the user about the current state of the unit. It is also welcome to have control modules for customization for a specific network. Thanks to this, service life and efficiency will increase.
Replacement battery. As practice shows, the first thing that fails is the battery. And this is normal, since the battery has its own cycle of discharge and charge, after overcoming which it becomes unusable. Therefore, it is important to buy a device that supports replacement. After all, it is easier to buy a new battery than to replace a working uninterruptible power supply.

In addition to the presented characteristics, some users pay attention to the presence of interfaces, degree of protection, etc. This is also important, but does not require close attention; these parameters, on the contrary, help you choose a practical option from two, at first glance, identical models. Therefore, it is the buyer’s right to ignore or look at them.

The products of this brand have been on the market for over ten years. This model went on sale not too long ago, and it is more powerful than other products from this company. It is produced using online technology (double conversion of electric current). The design is ideal not only for domestic use, but also for industrial systems, in particular, servers running on the Noveli, Windows NT, Unis, and so on platforms. Using this equipment, it is possible to eliminate any disturbances and malfunctions that occur in power supply networks. The rectifier makes the current constant, and it is in this section that the battery is charged and the inverter is powered. Based on this voltage, the inverter produces an alternating current of a stable sine wave.

All connected equipment is completely isolated from the external network, but at the same time they are provided with adequate power. If the voltage in the external network disappears, the product begins to use the energy accumulated in the batteries, the power of which is enough for 15-20 minutes, depending on how capacious the equipment is. You can control and configure the uninterruptible power supply using several mechanical buttons.

Because according to statistics, most PC breakdowns are not due to a “bad” manufacturer, but to careless use. If you have experience using uninterruptible power supplies described in the rating, or a more interesting model, tell us about it in the comments.

Is a UPS needed?

Many users wonder whether they need a UPS, because this is an additional cost, despite the fact that it does not in any way affect the performance of the PC and its other operational parameters. The question is quite reasonable and the answer to it may be different.

When a UPS is not needed:

old computer or cheapest one
The voltage is stable and rarely disappears
you have a backup of all valuable files
you are not embarrassed by the loss of unsaved files

When a UPS is needed:

the computer is of sufficient value
The network voltage fluctuates or frequently disappears
you do not have a backup copy of your valuable files
Losing unsaved files is critical for you

In any case, refusal to purchase a UPS is justified only with very limited financial capabilities. Since it will not only protect your files, but will prevent the system from crashing and the computer from malfunctioning.

If your computer or data is of any value to you, then I recommend purchasing a UPS, since restoration can be more expensive, not to mention the loss of time and nerves.
