Ultimate Buying Guide to the Best Power Supply for Gaming

How much power would I need?

There is no one answer. Different people have different PCs which require different power. You can enter the specifications of your PC on the internet, and it would show you the necessary power.

What is the 80 plus certification?

To understand the 80 plus certification, you need to know how a computer power supply works. The power supply has to convert the AC power coming from the wall into DC power that the components required to run. The 80 plus certification tells you how good the power supply is when it comes to converting AC power into DC power.

Should I use 12V supply if my circuit needs 9V supply?

No. This is not recommended. If your circuit uses 9V supply and you connect it with 12V supply, then chances are it will stop working altogether.

Why should I buy a power supply with gold certification over bronze or white certification?

There are two simple reasons why: one, it saves more electricity and two, even if you buy a 450W or 500W power supply with a gold certification, it will work efficiently.

How to choose the Best Power Supply for Gaming

Following are a few factors you should consider before buying a power supply for gaming:

  • Power

    The first factor to consider is how much power your PC needs. As we have already mentioned this before, you don't need to do some complicated math to figure it out. There are a lot of PSU (power supply unit) calculators online. Just enter the details of the different components your PC needs, and it would show you the total power you need. It will show the results in Watts.

  • Quality

    Considering a PSU converts power from one form to another, it is a sensitive machine. It is capable of breaking your PC too. However, you can make sure you don't have to face a situation like this. If a PSU has continuous or peak wattage rating, or only continuous wattage rating, you should go for it. But if a PSU only shows peak wattage rating, then don't buy it.

  • Appeal

    This factor depends entirely on your personal preference. If you care for a stylish design, then choose a power supply that looks good. An RGB power supply will suffice if you are looking for an aesthetic power supply. RGB LEDs can make even the most ordinary power supply look fun. For some people, however, the functionality of the power supply is enough.

  • Size

    Always make sure to note down the size of the power supply before buying it. Since different PCs have different requirements, you cannot just buy a power supply and expect it to fit inside your PC. Some PCs have less physical space, while others have a significant physical space. After identifying the physical space of your PC, you should buy a power supply accordingly.

  • 80 Plus Certification

    Your power supply converts AC power into DC power. During the process of conversion, your PSU is unable to convert the power 100%. The power that is not converted is lost in the form of heat. A low-quality power supply would convert less energy and waste more. This is precisely why they have introduced the 80 plus certification. You need to find a power supply that does not cost very high but also has proper efficiency certification.

  • Brand

    Some manufacturers are known for producing excellent power supplies. Some of them have even made a name for themselves for offering a wide range of power supplies- both expensive and affordable. Both of the options would have enough features to satisfy hardcore and average gamers. The brands that you have seen on this list produce top-notch power supplies.

  • Connectors

    If you want to be safe better than sorry, then you should consider this factor as well. A lot of people don't consider this factor too important, but we are mentioning it for your safety. Usually, the 20+4 connector is the most commonly used configuration. In this configuration, four pins are separate so that you can use them according to your needs.

  • Rails

    As the name suggests, the rails in a power supply are routes through which power flows to the components in a PC. There are two kinds of rails used in power supply: a single-rail and a multiple-rail. A power supply with a single rail does not divide the voltage. It delivers full value to a particular component. In a power supply with multi-rail, the voltage is divided into two or more parts. The risk of voltage fluctuation in the multi-rail power supply is lower as compared to the single rail power supply.

Concluding thoughts

Sometimes, even with the best options laid out in front of you, it can be hard to make a decision. That is why you need a buying guide, so you should make a decision. There are some factors you need to consider to help you in narrowing down the power supply unit that you find satisfactory. We have listed down all those factors. Gaming, for some people, is a way to escape the harsh realities of life. For that reason, they want a power supply that does not interrupt their gaming experience. Hopefully, this article has made your buying process a lot easier.
