Everything You Need To Know About UPS
If you are wondering how to combat the terrible electricity failures that are so common in India, especially the cities, you might know of two options that might be able to help. Either you can get yourself an inverter, or you can even invest in an UPS.
UPS are obviously much cheaper than an inverter, and at the same time, they are also a lot less powerful in comparison. However, if you want to power a PC to have a seamless work from home experience, you should consider a good UPS instead of a full-blown inverter.
But how to purchase the best UPS for PC in India? Well, first things first, you should get to understand what UPS’ are, what makes them special, and how to go about purchasing them.
A UPS is a great appliance if you want to protect your sensitive equipment from power surges, or you simply want to power them for a little while longer to save your project in case of a power cut. They are essentially a battery backup system and are highly effective during power supply interruptions, be it a complete cut, voltage fluctuations, or power surges.
So, what is a UPS really?
Power loss, power surges, and voltage fluctuations can prove highly damaging to your computer. It is very important to make sure that your equipment is protected from all of this, otherwise you might find yourself at a loss and replacing damaged components. A UPS is a great appliance that not only saves you from these power surges and such, but also allows you some extra time and power to save your work, or shut off your computer in a safe manner.
This might seem like a small thing, but continued disruption of power to your system can cause huge problems for your equipment and effectively render them unusable. The buffer your UPS can provide during a power cut depends on a few factors.
Firstly, it depends on the power your computer demands. For example, if you have a gaming computer with a big 27” monitor, you can be sure a more powerful UPS is needed to provide a viable buffer. Gaming computers are usually quite powerful and demand a lot of power, which means you have to invest in an equally powerful UPS that could be able to power your system.
Secondly, you would have to understand how the UPS power supply works. The power supply is measured in Volt-Ampere, or VA. At the bare minimum, you would need to invest in a UPS that allows you computer adequate time to properly power off. Anything below that is essentially just a waste of time.
How to measure how much power your computer needs and which UPS to invest in? That much is simple, you can either use a power meter to get an accurate measurement of the consumption patterns of your computer. If that is not feasible for you, the best way to do that is to understand the power supply rating for your computer. You would only need to look at the PSU, sometimes called the SMPS, to determine how much power your computer would need. The PSU supplies power to your computer, and if you know how much wattage it is, you can use that information to invest in a UPS accordingly. For example, your PSU is 400W, so to power your cabinet, you can use this formula –
1.6 x Wattage = Minimum VA needed
So, to run a 400W PSU, you would need an UPS of at least 640VA. However, this does not mean your entire computer will work with 640VA. You would have to power your monitor as well. Most monitors are around 15-40W. Which means the total power you need would be around 420W-450W. The UPS power required increases too.
There isn’t really a quick rule-of-thumb to calculate how long the UPS will last, but getting an overpowered UPS is better than having an underpowered one.
For gaming computers that have a bigger PSU, generally ranging from 550W-650W, and probably a 144hz, bigger monitor, you are looking at a wattage of around 700W. Essentially, you would want to invest in 1120VA.
There are 1100VA UPS out there that prove incredibly useful for most computers. I would suggest nothing less than that if you own a good gaming computer. For most normal workstations, 1100VA would be highly beneficial, but you can easily work with a 600VA as well.
That is more or less it. All you have to know about UPS and how to go about purchasing the one that best suits your needs. Since desktop computers do not have a battery like laptops do, during power cuts, there are a lot of issues that can befall your system. Power surges can destroy components, fry peripherals, and there is always the possibility of losing your work and data if there is a sudden power outage.
To safeguard your computer and make sure you get to complete your work, or at least save it, a UPS proves incredibly useful. There are also special UPS in the market that provide you with some additional features. There are UPS that can be switched on-off using your phone, UPS that come with a digital screen to display how much battery it has left, and so much more.
You should also keep an eye out for the number of sockets the UPS provides. Also, do check what style sockets they are – most bigger PSUs come with the type-G plug, which means you would need a socket that can fit the plug. You can always get an extension plug, but it is always a good idea to check the number of sockets on the UPS and the type.
