With gaming becoming more and more exciting and addictive, many people today prefer building their own gaming PC’s. Many people prefer building a PC over buying a ready-made one for numerous reasons. When you choose to build a PC, you have full control over what parts you want on your PC and from who you want them. Although this sounds like a great idea, it can often cause performance issues if the components aren’t chosen well. One of the most overlooked components during the component-choosing process is the power supply. The power supply is like the heart of the computer. Without a power supply, there is no way that your computer can even run. Most people who are unaware of this components importance may choose to settle with stock or a low-end power supply.
When building a gaming PC something like this is not at all recommended as the quality of the PSU you choose will dictate what other components you can put into your computer either when you are building it or even in the future. Although a high-end gaming power supply will not directly alter your gameplay or framerate, it is still an essential component in a PC. For example, if you choose to go with a low-end power supply, you will not be able to put in a high-end graphics card or a high end cooling unit as there won’t be enough power to keep them running.
In this post, you will come across some of the best power supply units in the market ranging from 400W to 1000W and above. So whether you’re searching for the best power supply that you won’t have to replace for a long time or even if you’re just wondering which of the best power supplies are sufficient for your gaming PC, this guide will assist you in buying the best power supply to make your gaming experience as excellent as possible.
The power supplies have been categorized based on their output rating to help you choose whats best for your setup.
The best power supplies between 400W and 600W
This range of power supplies is the most practical for the majority of gamers out there. If you happen to be building a budget gaming system, a 450W power supply should be more than enough to keep you going. Even if you’re going with a powerful video card, these power supply’s should satisfy your power needs. So unless you’re building an extreme setup that utilizes multiple video cards (or plan to in the future) the power supplies in the list below are probably components worth considering.
EVGA SUPERNOVA 550 G3 review
The all new EVGA SuperNOVA 550 G3 is an improved adaptation to the G2 model, in a smaller chassis for ease of transport.

Power supplies between 800W & 1000W

Need help choosing the right unit?
To choose the right power supply unit, it is important to take many things into consideration. For those looking to build a gaming PC, there are a number of categories to think about before you come to a conclusion. Some of the most important features to look for are:
Wattage: Choosing a power supply with the right wattage is perhaps the most important step. In order to choose the right wattage, it is important for you to have a rough estimate of how much power your components need. Do keep in mind that a higher wattage can not only be more costly, but it may also help with heat and noise levels.
Modular: Another thing to consider when selecting a power supply is whether you want a modular or fixed unit. While modular or fixed is a simply a matter of opinion, choosing a modular unit can prevent unnecessary clutter in your computer and lead to improved air flow.
Optimal Form Factors: If you want a higher powered computer, you’re going to need the most current form factors, such as ATX 12V v2.4.
Efficiency: For the good of your newly built PC and also for the good of the planet a Gold rating or more is highly recommended as it consumes lesser energy and gives you a much better energy efficient output.
Overall if you want to have the ultimate gaming experience without shortening the life of your computer, Consider your needs both now and in the future, so that you can make the best possible choice for long-term gaming enjoyment.
