PSU Tier List 2021 – Complete Power Supply Unit Hierarchy

Tier S – The Crème De La Crème

The number of PSUs mentioned in this tier list is definitely the best ones available in the market because of their Platinum and better 80 Plus rating, reliability, unique features, wattage range, price, and Japanese-made components. It would be a hard task for you to find models better than these.

On the other hand, they are completely suitable for those types of enthusiasts who have a significant budget and don’t settle for less. There are a lot of NVIDIA GeForce Titan V GPUs complimenting the most recent Intel Core i9 are they are pretty much on the waiting list of these power supplies.

For an average gamer in search of a PC build reliably for playing AAA games on normal settings, all of these units turn towards the requirements and are the best.

PSU Tier 1 – Awesome Power

The units in Tier 1 are lower in terms of price, yet they still offer remarkable power solutions with great reliability. On the other hand, they are better for demanding powerhouse equipment with expensive components to work.

Furthermore, if you are on a budget, then there is nothing wrong happening with you in this tier, as it contains the most budget-friendly and performance filled units ever. In addition to this, it is a wise option to go for Tier 1 when you want to future-proof a build and enable extra room for the internal components with demanding power requirements.

PSU Tier 2 – Expensive Quality

The Tier 2 goes down price-wise again, and the units are perfect for veteran builders who are in search of not just a good looking, but a reliable PSU without having to spend too much from their savings. For the products in this tier, you pay for quality, and every penny is worth it.

However, first-time PSU buyers might want to stay clear with the prices because it can still be an issue for them.

PSU Tier 3 – Reliable Power for Price

In this tier, we enter into a world of PSUs that are suitable for a majority of gamers who desire a functional machine with commendable components that won’t fry or buck after heavy usage. In addition to this, the PSUs in this tier are both quality-filled and affordable as well.

PSU Tier 4 – Mid-Range Choices

In the fourth tier, we offer one of the most reliable models on the never-ending catalog of awesome PSUs on sale. They work fine, but they do not contain any extra features.

On the other hand, efficiency is not sacrificed in the tier. In clear words, the fourth tier represents mid-range, not-so-great PSUs that are kind of acceptable in terms of price and performance.

PSU Tier 5 – Budget Choices

From here to the end, we are afraid to say, everything is downhill. Tier 5 is basically for all the budget options, and if you are a PC gaming enthusiast, these units will definitely give you goosebumps.

However, if there are any users that are able to spend extra cash on a better CPU or GPU, then these PSUs are kind of beneficial.

PSU Tier 6 – Cheerful and Cheap

The Tier 6 PSUs are tricky ones; they may work well, but they may end up being useless. If you ask us, it is best to stay clear if your budget allows it.

It is easy for an enthusiastic PC builder to rant about the flaws of these PSUs. They offer the most basic and not-needed functions, and that’s pretty much it. In addition to this, these PSUs barely go 80 Plus rating.

PSU Tier 7 – Base of the Drum

The PSUs in this tier for everything they have to offer shouldn’t even be in the market. In a lot of ways, gamers should demand a price to use these units rather than actually using them because they are a waste of money.

Why is Your Power Supply Choice Important?

Here’s one very essential thing you must know:

If you purchase a low-quality PSU, then you won’t be able to switch to a high-end graphics card. In addition to this, your gaming power supply will not be strong enough to give you an enhanced gaming experience or a better frame rate, but still, a PSU is an essential component.

So, it is crucial for you to make the right choice by keeping the sole purpose of creating a high-quality gaming computer in mind.

A power supply of 800W-1000W is not enough unless you use a multiple video card configuration and get some extreme type of overclocking happening. However, you don’t need that much power to better your gaming PC.

7. Is it necessary for me to have a nice Power Supply for Gaming?

Do not worry about yourself if you are confused to answer some of these questions. By the end of this buyer’s guide, you will surely end up with accurate answers and theories to what you are going to do.

Finding the Best PC Power Supply Unit

Power supply units are considered to be the most important part of your computer, which can turn this upside-down if not chosen correctly.

If your PC is running completely fine without a Power supply unit, then that doesn’t mean that the system is okay like that. There often comes a time when your PC will demand more power than usual.

For instance, when overclocking your PC’s RAM/CPU/GPU, there will be a high rate of power consumption. In that case, it is necessary to own a high-end PSU to provide the necessary power. The process of purchasing the right PSU means to make a decision that will support your future upgrading of components effortlessly.

However, finding the best PSU is not a child’s play. It is important for you to have enough knowledge about PSUs before purchasing one. There are a number of multiple factors that you must understand.

You must be wondering, what happens if I purchase a cheap yet high-wattage PSU or just an expensive one?  The answer to that is simple; this is exactly how people fall in traps with power supplies in the first place. But you shouldn’t worry because this guide will help you a lot.

How Many Watts are needed for a PSU?

It does not make sense to buy a very powerful power supply that you are never going to need. You can understand the kind of power needed for your system to run with the help of some power consumption calculators.

There are plenty of reliable power consumption calculators available in the market, but still, we have created a list of some of the best ones that will be of help to you.
