A Power Supply Unit (PSU) is a critical component in any PC setup, yet it is often overlooked. Selecting the appropriate PSU for your specific configuration can be daunting due to the multitude of options available on the market. To simplify this process, we have created a comprehensive guide to assist you.
In this guide, we will outline the types of PSUs available in the Indian market and provide you with easy-to-follow steps for choosing the best one for your needs. It’s important to note that you don’t necessarily need the most expensive PSU; you simply require one that is well-suited to your setup.
One crucial consideration when purchasing a PSU is determining how much power it needs to supply. The power requirements depend entirely on your individual PC and its components. More powerful systems with custom cooling, multiple GPUs, and numerous fans will naturally demand more power to operate efficiently. We recommend utilizing a PSU Wattage Calculator, such as the one provided:
By employing this calculator, you can determine the power requirements of your system, ensuring smooth operation without any hiccups. As a general guideline, it is safer to err on the side of higher power wattage rather than falling short. For instance, if your system requires 400 watts, opting for a PSU with a capacity of 600 or 650 watts is a better choice. This decision provides ample headroom for the system to function optimally and accommodates any future upgrades without exceeding the total power draw.
However, it’s important to note that using a significantly higher wattage PSU will not enhance performance, so it’s unnecessary to go overboard with excessive wattage. Opting for a PSU with approximately 200 watts more than your required power draw should be a suitable choice.
Efficiency (Bronze ,Silver ,Gold, Platinum, Titanium)
Another important thing when buying a PSU is its efficiency. The more efficient a PSU is, the less power it wastes. A low efficiency PSU will also tend to heat up more,which can degrade its lifespan.
Fortunately, to compare efficiency, a rating system is already in place and is standard worldwide. The efficiency increases as the rating increases. They are:
- 80 PLUS
- 80 PLUS Bronze
- 80 PLUS SIlver
- 80 PLUS Gold
- 80 PLUS Platinum
- 80 PLUS Titanium
You should know however, that the more efficient PSUs are much pricier than the lower efficiency ones. So it’s a matter of trading off of price vs efficiency.

Modular vs Non-Modular
The main difference between a modular and a non-modular PSU is that a non-modular PSU has all the cables pre soldered to the circuit board. Which means you don’t really get to choose what kind of cables you want in your PC build. And if you have cables you don’t need in your system, they will still be connected to the PSU and you will have to conceal them one way or another.
Modular PSUs do not have cables attached to them. This means more freedom to configure but it also means you need to know what you are doing and how you want your setup to be. For cleaner setups,this is the way to go.
There is also a middle ground, a semi-modular PSU. In this type of PSU, only the frequently used cables are pre soldered and the rest you can configure yourself.
