With a variety of different options, there comes a question: Which one should you go for? Are they all the same, or is there any difference between them? What is the best PSU Tier List in 2021? Well, as you’ve always ignored the PSU hierarchy, you need to know the basics about it.

This article will discuss all the details about the PSU hierarchy, where to buy one, and, most importantly, which are the best PSUs available in the market.

The Ideal PSU Tier Guide

Are you searching for a compatible PSU with your PC and are confused about the required features of a good PSU? Then you need to know about the PSU Tiers and ratings of different PSUs available.

In this section of the article, we will tell you about the ratings and tiers of the PSU and by which piece of hardware they are inspired.

Most people don’t realize this, but the PSU, AKA Power Supply Unit, is your PC’s most important and main component. The lifespan of other computer components solely relies on the choice of PSU you make because the wrong choice can get you into a lot of trouble.

PCU Hierarchy Tier List

Any PC building enthusiast needs to track down the most reliable components to go with the structure.

We have divided power supply units into tiers from the best to the least based on the overall performance, price point, and efficiency to make your journey bearable.

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 enthusiasts who have a significant budget and don’t settle for less. Many NVIDIA GeForce Titan V GPUs compliment the most recent Intel Core i9 are they are pretty much on the waiting list of these power supplies.

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

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.

The Tier 6 PSUs are tricky ones; they may work well, but they may be 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.

Why is Your Power Supply Choice Important?

Here’s one very essential thing you must know:

If you purchase a low-quality PSU, 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 would help if you made 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 extreme overclocking. However, you don’t need that much power to better your gaming PC.

7 Factors to Consider Before Purchasing a PSU

As mentioned above, there are some questions you need to ask yourself before you buy a PSU. If you search for the answers to the above-written questions, then you will definitely get a better clue about which PSU to get from the multiple options available to you in the market. Following are the major seven factors to consider before you purchase a PSU:

  1. Should I purchase a modular Power Supply?
  2. Is it important for me to save energy?
  3. How many Watts are needed for my gaming PC?
  4. What is meant by an 80Plus rating?
  5. What is meant by the +12V Rail?
  6. Is it possible to have excessive Wattage?
  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 will do.

Finding the Best PC Power Supply Unit

Power supply units are considered 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 power consumption rate. 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 making a decision that will support your future upgrading of components effortlessly.

However, finding the best PSU is not a child’s play. You need to have enough knowledge about PSUs before purchasing one. There are several 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 into traps with power supplies in the first place. But it would help if you didn’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 potent power supply that you will never 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 we have created a list of some of the best ones that will help you.

  • Cooler Master Power Calculator
  • MSI PSU Calculator
  • Seasonic Wattage Calculator

4 Necessary PSU Ratings Discussed

Power Supply Units are marked with the four most important ratings, which give you an idea of what kind of outputs you will get from the PSU.


An efficient PSU means minimum electric consumption and more affordable e-bills. The more a power supply is efficient, the better outputs it can provide you with.


One of the most required and necessary features of a good power supply is stable. If a power supply is not stable, it might shut down or deliver low performance under high temperatures or other situations.


The safety of your PC components depends upon the kind of power supply you use. A reliable power supply is always well-manufactured and features nice safety mechanisms like UVP- Under Voltage Protector or OVP- Over Voltage Protector, etc.

4. Components used

The power supply features rectifiers, regulator circuits, filters, and transformers. Most power supplies often come with nice cooling fans. If all of these components are of good quality, your power supply will perform as well as possible and last for a long time.

In conclusion, these factors play a vital role in the performance of the Power Supply Unit you choose. In addition to this, power supply units have the following type of ratings:

80+, Gold, Titanium, Bronze, Gold, and Silver, but some power supplies are not equipped with any ratings.
