What constitutes a UPS System?

In simple terms, a UPS system is a simple battery-based backup power system. The primary function of the UPS is to supply power long enough to enable you to shut down your PC when the main power supply fails.

Resultantly, you get a chance to save your data. You also protect your PC from unnecessary damage as a hard shutdown can cause a lot of stress to your PC system.

Secondly, the UPS acts as a surge protector. It can protect your PC and the accessories from surges or abnormal voltage fluctuations.

The need for a UPS system

The UPS system is such that it automatically switches over to the battery mode during a power failure. The battery gets charged when the power supply is on.

During a power outage, the battery of the UPS system supplies the necessary power to your PC. Your PC does not black out instantly. Hence, you save the PC from damage.

Depending on the type of UPS you use, the battery has a specific backup capacity. Usually, you do not require much time to save your work and shut down your computer properly.

Thus, you get some breathing time to shut down your PC or the video gaming consoles without suffering any loss of data.

The UPS is handy during heavy voltage fluctuations. It can protect the PC from different types of power problems. Let us discuss the different types of power problems you usually encounter at home.

Types of Power Problems

When we talk about power problems, we consider power blackout as the only power problem. However, it is not so. There are different types of power problems. Here are some of them.


Blackouts can range from a few seconds to even days. The reasons for interruption can be bad weather, grid failures, or utility power shortages.

Load Shedding

It happens many times that power companies lower the voltage of the electricity to avoid total blackouts thus resulting in a disruption in your power supply for a specific period. You know it by the term load shedding.

Voltage Surge

Voltage surges are sudden occurrences that have the potential to damage expensive electrical and electronic equipment.

Voltage drops

These are similar to voltage surges, but it involves low voltage. It can also harm your PC components.

There are other problems such as frequency noise, frequency variation, and harmonic disruption. All these power problems can harm the delicate components of your PC.

The UPS can take care of these problems by ensuring that your PC receives the right current at the optimum voltage.

Different Types of UPS Systems

Different types of UPS systems are available. They are the Standby, Line-Interactive, and the Online UPS unit.

Standby UPS Unit

Almost everyone has this type of UPS for their home PCs. The UPS unit works by charging the battery when the power supply is on and switches the power supply to the battery back up the moment the mains supply fails.

This automatic switch takes about 20 to 100 milliseconds. It is within the tolerance threshold of your PCs and other electronic equipment. Hence, the appliances do not switch off.

Line-Interactive UPS

This UPS system is similar to the standby UPS but includes a special transformer. The transformer is extremely useful in areas that experience voltage drops.

You notice that the lights become dim during voltage drops but do not switch off completely. The Line-Interactive UPS helps to increase the output voltage thereby ensuring that your PC receives the optimum voltage at all times.

Online UPS System

The online UPS system is different from the standby and the Line-Interactive UPS system in the sense that it does not wait for the power to switch off. It continuously filters the input power supply through the battery system. You can compare it to the home inverter.

It ensures that the PC and the other appliances attached to it receive constant power supply through the batteries even when the power supply is on.

It replenishes the battery on a continuous basis thereby ensuring that there is no break in the power supply to the PCs. These UPS systems are comparatively expensive to the other two types of UPS systems discussed above.

It is also referred to as the Double Conversion UPS system.

What type of UPS do you need?

Your UPS depends on the type of power problems you face. The standby UPS system should suffice if you encounter challenges like load shedding, blackouts, and voltage surges.

If you experience continuous voltage drops and surges, you should use the line-interactive UPS system. The double conversion UPS or online UPS can tackle all kinds of power problems including line noise, frequency variation, and harmonic distortion.

What should be the capacity of my UPS?

At the minimum, you need the UPS system to provide power for a duration long enough to enable you to save your work and shut down the computer safely.

If your UPS is capable of providing this power, it should be sufficient for normal domestic use. Otherwise, you risk damaging your computer and its expensive components.

The question on everyone’s mind would be how to determine the capacity of their UPS. There is no specific formula as such, but you can use this thumb rule for deciding how much UPS you need.

Every PC will come with a power supply rating that indicates the maximum power a computer will pull.

Secondly, you might also have some peripherals such as monitors, external hard drives, printers, and so on. You have to keep the power load of these appliances as well.

If your PC comes with a power supply rating of 400 Watts, it will not be pulling a constant load of 400 Watts. Usually, the start-up load will be around 300 Watts, and the operating capacity will be in the region of 250 Watts.

However, you should always go with the maximum power supply rating of your PC while choosing your UPS. The general formula is as follows.

Minimum Volt-Amperes (VA) = 1.6 times the Wattage load

In our case, it is better to go for a UPS system with a minimum VA rating of 640 VA.

In the ordinary course, your home UPS system should accommodate a minimum of three appliances. Thus, you should go for a UPS that has provision for connecting three power cords.

Secondary Features

Fundamentally, your UPS is a sophisticated battery. However, you should go for a UPS system that has various additional features.

  • Ensure that your chosen UPS communicates accurately with your attached devices. Today, you have UPS systems that come with multiple connectivity ports.
  • Your UPS should also be compatible with the OS you use. Under such circumstances, you will get an alert that the PC is running on the UPS thereby enabling you to initiate the shutdown process.
  • Voltage surges are frequent in India. Hence, you should check whether your UPS includes surge protected/filtered ports for your Ethernet cables.
  • The UPS systems available today come with display systems. The low-end UPS systems and the older systems do not have this facility. The display panels provide you additional information such as remaining runtime, battery health, and so on.
  • Not all UPS systems have fans. The larger ones have them. Check out the noise that these fans make. It assumes greater significance if you connect your home theatre to your UPS. The sound can interfere with the output.
  • Usually, UPS batteries last for three to five years. Some UPS systems allow you to swap the exhausted batteries with fresh ones. The low-end UPS units do not have this facility. You would have to discard them and buy a new UPS system. It is better to choose a system that permits swapping of batteries.

Price Range

We spend a lot of money acquiring our PCs and other equipment. We need to safeguard these appliances from power outages and other power-related problems.

In this context, using a good and compatible UPS system is necessary. Spending a few thousand rupees to protect your PC and other appliances should not be an issue.

You get a good quality UPS system in the range of ₹ 5000 to ₹ 10,000.

Final thoughts

The PC and other peripherals are valuable equipment. There is a need to protect them from sudden power outages. Hence, one should install a UPS system to take care of power fluctuations.

The UPS systems provide you with a specific time window whereby you can save your work and safely shut down your PC. It protects the equipment from damage.
