PSU Tier List 2021 – PSU Hierarchy

In general, the PSU (Power Supply Unit) is always ignored. Several customers do not buy PSUs being not familiar with the product.

But if you look around the market, there are several Pc PSUs available, in such a quantity that it becomes hard for you to decide which model to select.

But

The question on almost every customer who is fond of gaming comes is that what is the best PSU for gaming?

To answer this question, some products are listed below based on their quality and considering their prices. Before moving any further, it is essential to tell what the PSU tier list exactly is?

Most users, especially those who have games on their PC, know about them. It is a device that is attached to your desktop system, and further, it converts Alternating Current (AC) to Direct Current (DC).

Why is this so because your PC works better and needs DC for proper functioning. Additionally, it also controls the overheating of your PC.

Most of the PSU comes inbuilt with the system. However, the people who are a massive fan of gaming and other stuff do consider that an extra PSU shall be attached. Once you have it, you need to be very careful and productive.

PSU Tier List 2021- A Summarized Table

Here is an ultimate Power Supply Tier List for you so that you can select the best one according to your requirements.

The top Platinum tier is dedicated to high-end PSUs. These ratings are usually 1000+ making them suitable for flagship models and gaming beasts. These Power supplies are one of a kind you can get your hands on. It’s surprising to see that these PSUs are usually kept for enthusiasts who are into building a gaming rig with expensive components. Well, these PSUs are recommended for GPUs like Nvidia RTX Titan V. Similarly, if you are blessed with core i9 9900K, then what are you even waiting for?

Unfortunately, if you are a budget gamer, then these PSUs are a big no for you!

Tier A is another withstanding list that is limiting to huge powerhouse machines. If your system harbors high-end and flagship models which are hungry power machines, then these PSUs are made just for you.

 Tier A’s rating staggers between (800-1600) which is ample to turn on the powerhouse. These PSUs are also reviewed to be best for on-spree gaming and rendering purposes. How about you buy the AMD Thread ripper already? Read BEST Power Supply for GTX 1080.

Tier B requires you to be well-versed regarding the modulation and the norms regarding a PSU. It’s been endorsed carefully, that you spend your savings in a right direction. This tier holds all the veteran and top PSUs that can save you for a lifetime.

 It’s worth noticing that these PSUs are still costly, but incredibly powerful and useful for 4k+ gaming and rendering. Not to mention, this is the tier that also harbors most of the PSUs, so your ultimate shot is to find the most reliable and worth spending PSU.

The silver tier incorporates most of the top-notch PSUs with lowered price tags. In short, you can easily buy off a PSU from this tier without spending too much.

Notwithstanding, this tier is sufficiently powered and protects your components, regardless of taking the 4^th spot on the tier list. It’s worth mentioning, that if you are a budget gamer who has realistic dreams, then the PSUs from this tier is just for you.

It’s certainly understandable that you might be having afterthoughts regarding the bronze tier. This is the tier most suitable for budget-friendly gamers who are pursuing mid-range gaming rig. affordability is the key element for this tier. You don’t have to worry about the performance of these PSUs, they are still of high quality and have a name in the market.

Tier E takes on PSUs that are below the bronze belt, giving you mediocre performance spikes. It doesn’t necessarily connote them being a deserted choice. You can still make most out of them, sort of juicing in performance.

Surprisingly, these PSUs can be bought easily by budget-fanatics, who are not looking to spend a lot on PSUs. So yeah, that’s the gist regarding this Tier.

I would like to break it to you, that these PSUs fall below the recommended threshold, hardly touching the 80+ rating efficiency. They are most suitable for powering purposes, and that’s all. If you have RGB’s or greedy components that munch on greater power Rate, then this tier is just not for you.

Well, if you have a much lower-end PC for office purposes, then sure go ahead with these nearly-ancient PSUs.

Not recommended at all. This carbon tier is known for exploiting components. They seem sketchy and provide zero protection features. If you are in the mood to burn your pc to cinders, then why not. Go ahead with this tier and buy the PSUs.

Honestly speaking, these PSUs shouldn’t exist anymore. They are endangering expensive components. In short, stay away from them!

Importance of the Best Power Supplies

A good quality PSU is highly recommended as this allows you to upgrade to high-end graphics. The low-quality PSU does not allow you for up-gradation, and you have to become restricted.  

It is an essential element because the gaming power supply remains unable to provide you with a facility to experience outstanding game quality without it. In this regard, you have to select the best PSU for a high-quality gaming experience.

The 800W-1000W range is not a good option when you want to run numerous video card configurations on the same extreme system. Therefore, do not for higher power too but go for a good PSU.

Before Buying, Things to Consider:

If you are here looking for the best PSUs for you, you are in the right place. Here are the PSUs hundreds of companies manufacturing. That brings you to a question: which one is the best? Are all PSU the same? What thing makes which PSUs different from the rest? How to opt for the perfect PSU for me?

We believe that these are the few queries that need to be clarified. Before moving forward, let us explain and place in front the names of the available brands; CoolMax, Corsair, Antec, Seasonic, and Ultra. Selecting a PSU from one of the best-renowned brands does not guarantee quality. You need to go through the multiple steps to opt for the best PSU for yourself.

Before we begin, just imagine that you are ready to buy the best processor from the market. Let’s just suppose that you find two most famous companies for it; Intel and AMD. Now it’s not that simple. You buy a processor, an Intel or AMD will satisfy all of your demand. Similar is the case with PSU.

Components Used

Some critical components are used in the PSUs. A list of those components is given below.

• Filters, Rectifiers, Transformers, and Regulator Circuits.
• Most of the PSU come with fans with silent features, and some are fan free.

If your PSU does possess all of these components of good quality, then definitely you have selected a reliable PSU. But still, you need to understand the details about what steps to be followed to opt for the best PSUs.

Some of the Common PSU Ratings:

PSUs usually come with a surfeit of gradings and a discrete certification system. One of the most popular certifications is mentioned below:

• 80 PLUS
• 80 PLUS BRONZE
• 80 PLUS SILVER
• 80 PLUS GOLD
• 80 PLUS TITANIUM

Safety Measures:

All the safety of your components depends on the type of power supply. The more reliable power supply, the more you will be secure. PSUs are embedded with automatic shutdown systems that help them to not malfunction and destroy the expensive components.

OVP (Over Voltage protection): An automatic shutdown features that activate when the power exceeds 110% of the rated grading.

OPP (Overpower protection): Usually, activates when the power grading exceeds 130%.

OCP (Over Current Protection): This integrated sensory detection happens when the PSU is overloaded with the current. Edgy currents can also promote this sort of behavior, leading to a complete shutdown. Since current production involves heat dissipation, it’s worth noticing that the feature has its advantages.

On the contrary, it could be disadvantageous as well. Some of the time, components require more current. This triggers the sensory alarm in the PSU resulting in another shut-down. So yeah, it’s cumbersome.

SCP (Short circuit protection): short circuit can be minimized with the help of this feature. When CPUs and GPUs run hotter, and juice out more current from the PSU, the PSU disconnects itself from short-circuiting the transistors on the motherboard. Otherwise, your system can die predominantly.

BOP (Brown Out protection): Inconsistent electrical grids and fluctuation in voltage levels can do more severe harm to your components. This feature eliminates such possibilities.

OTP (Over Temperature Protection): When the temperature inside the case exceeds the threshold, the PSU automatically shuts-down the system.

Stability

The stability of a power supply is directly proportional to the power grading, and the type of PSU. Most of the locally manufactured power supplies tend to run erroneous, indicating a dead end for your components. Make sure you buy a power supply which is greater than the added TDPs of all the components, otherwise if by chance, it’s lower, then you have no choice but to pray for your components for living a little longer.

Wattage of PSU

If you believe that the power of a PSU depends on increasing the output in watts similarly as someone may think that the power of a motor car depends on the bigger engine.

In both cases it is wrong. So how do you select the best powerful PSU that can complete your desire in the gaming world? 

Therefore, if you are confused about deciding what PSU best supports your system. You need to understand some basics. That is to say, PSU is mostly rated between 200 to 2000 Watts.

Now what you need to do is that you must calculate the required power of your Central Processing Unit (CPU) which is known as Thermal Design Power (TDP).

In short, TDP is the aggregate of the power requirements of all the elements on your computer. Are you confused about calculating this? Here is a simple solution to your problem.

Several online calculators are available to figure it out. Just put the required values in their places and the machine will calculate the TDP for you.

Users’ Reviews

Some companies are working on manufacturing PSUs. You might end up confusing yourself about which company’s product to root for. To understand which PSU is reliable and can fulfill all of your demands, you must go through the customer review section.

That will solve your problem and through this, it will become easy for you to select the best PSU for your system.

Efficiency

For better understanding the efficiency of the PSU. This is not enough that it does not get very hot and things like this.

Rather, if you are familiar with the PSU or even if you have seen the PSUs in your life you may have heard about an 80+ rating.

Now, this is an important part. Some of the ratings are 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, 80 Plus Platinum, and 80 Plus Titanium.

As you can yourself figure out that the best among these 5 is TITANIUM. This is the best rating that a PSU can get.

The concept of this 80 Plus rating means that the PSU is efficient to the tune of 80%. Now the problem arises: what rating must you go for?

For instance, if you have a 16-core processor which is overclocked to 5GHz and your room temperature is controlled with some air cooler. You may require 80 Plus Silver. But 80 Plus and 80 Plus bronze are enough in this case.

From the above example, you must be pretty clear about which PSU rating is best. Most of the gamers prefer 80 Plus and 80 Plus Bronze. These two ratings best suits and even satisfy your demands as well.
