In this article I will tell you about the ratings of the PSU and on basis of which things they are made.

I will also let you know about the tiers of PSU in 2021 by which you can get an idea about which ones are best and which ones are the worst.

This is a fact that:

Power Supply Unit aka the PSU is one of the most important component of your PC.

If you don’t know about what your current power supply then checkout our separate post on what power supply do I have.

Choosing the best PSU for your computer is very essential to ensure the lasting of the other components. Wrong PSU for your PC may cause serious damage to the components. And it can get you into a great loss.

which -powersupply-is for-you

Why Getting a Good PSU is Important

Getting a good power supply (PSU) is really important because: If you buy a low-end PSU then, you won’t be able to upgrade to a high-end graphics card.

Your gaming power supply won’t give you a higher gaming experience or higher frame rate, but it’s a quiet essential component. As a result, you need to take your decision wisely with the purpose of building a high-quality gaming computer.

Even a power supply of 800W-1000W range is going to be overkill for you unless you run a multiple video card configuration and getting into some extreme system overclock going on.


There really isn’t a need for this much power.

Important Reminders When Buying a PSU

I have given some common as well as very important that you need to ask yourself before purchasing a PSU. The answers to these questions will give you a better idea about which one to choose from those many options that are available on the market.

  • How Many Watts Do I Need for My Gaming PC?
  • What is the +12V Rail?
  • What is an 80Plus Rating?
  • Should I Get A Modular Power Supply?
  • Do You Need A Good Power Supply for Gaming?
  • Can You Have Too Much Wattage?
  • Is Energy Saving Important for me?

Don’t worry if you are confused to answer. By reading this post till the end you will be sure of what are you gong to purchase.

How to Pick The Right PSU

You need to calculate your power usage (watts), system type and rating for picking the right Power Supply Unit (PSU).

Power supply units are the most sensitive part your your computer which can cause a big harm if not chosen wisely.

Your PC is running nicely with your power supply unit doesn’t necessarily mean that it’s perfect/sufficient for your PC. Sometimes your PC may require more power than usual times.

Moreover, while overclocking your PC’s CPU/GPU/RAM power consumption will be very high.So, for such a high end PC a Beast Power supply is  a must.

It gets better:

When you choose a PSU perfectly and it is also capable to run your future upgrading component smoothly.

But choosing the perfect Power supply for your PC isn’t a child’s play.

You need to have a good amount of knowledge about PSU before buying it. There many factors that you will need to understand separately for this.

You might be wondering:

What if I buy  a cheap but high wattage PSU or an expensive PSU?

The simple answer:

That’s how people fall in trouble with power supplies for the first time.

Don’t worry.


Read till the end and you will get to know all about power supplies and which one is the most suitable for your PC.

Also check out how to turn on 144Hz on your monitor.

How Many Watts PSU Do I Need

You can get to know about how much power will your new system require by using some power consumption calculators to calculate PSU watts.

To spend money on a way more powerful power supply than that of you will ever need.

I have given some links of some power calculators below that will give you a good idea about your system’s power needs:

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

What Does Rating Mean on PSU


Power supply units have 4 important ratings marked on them which give you the information of what can you get as output from the PSU.

  • Efficiency

Efficient PSU means less electric consumption and fewer e-bills. the more a power supply is efficient the more it can give output with ratio to it’s input.

  • Stability

Stability is one of the most important feature of a power supply. If a Power supply isn’t  stable enough,then it may shut down or lower its capacity under high temperature or other circumstances.

Talking of stability, here is a stable fix for scratch disks are full.

  • Safety

All of your PC component’s safety depends upon your power supply. A good power supply is always well built and has good safety mechanisms like OVP (Over Voltage Protector) and UVP (Under Voltage Protector) etc.

  • Components used

A power supply is generally consists transformers, rectifiers, filters and regulator circuits.

Some power supplies also come with good quality cooling fans. if these components are of good quality then the power supply will perform better as well as last for longer period.

These factors have a great impact on the performance of the Power Supply Unit. The Power supplies have ratings like:

80+, Bronze , Silver, Gold, Platinum and Titanium. Some power supplies don’t have any rating at all. These ones are recommended to be ignored while building PC.

Besides these ratings you can also choose your PSU by observing my given Tier list for PSU in 2021. I have made a list for you to get a clear idea about which power supply to buy.

Based on factors like Efficiency, stability, components used and safety I have made this tier list.



Question: Does PSU rating matter?

Answer: Yes,there are few differences in performance.

Question: How does PSU tier help?

Answer: It helps in differentiating among the PSUs and also classifies the PSUs among groups to know about which one is better.

Question: What is modular PSU?

Answer: : Modular PSUs are the ones having no cables attached to them BUt they come with cables so that, you can use cables as your want.

Question: What is semi modular PSU?

Answer: Semi Modular PSUs are the ones having only the cables of 24 Pin and Pin cables attached to them and they come with other cables too so that, you can use cables as your want.

Final Thoughts

Choosing the Right PSU for you is as essential as protecting your PC from any horrible damage.

Choosing the Right PSU for you is as essential as protecting your PC from any horrible damage.

Good power supply units can cool it’s internal body efficiently and doesn’t spread heat inside the PC case. for this the PSU needs to have good Fan. Some of the new PSU also have the feature to change the fan or upgrading them.

Talking of thermal issues, you can fix your PC’s thermal problems very easily with few tricks. We have a separate article on How to monitor CPU & GPU temperature where you can find the easiest way to control your PC’s temperature.

If you choose a weak PSU you will need to upgrade it while upgrading other components of your PC.

So, I will recommend you to spend your money a little bit more for buying a good PSU for your PC.
