What Is A Modular Power Supply Unit

Whenever you are building a new gaming PC, one of the most important components that you have to go with should be the power supply unit. Without a good power supply unit installed in your PC, you are putting the rest of the hardware at risk.

Even though modern-day components have several redundancies built into them that prevent such failure, it is still a better thing to do avoid any mistakes that might cause more issues.

Now when you are buying a power supply, you will come across different efficiency ratings, as well as different types. For instance, you will come across power supply units that will be 80+, bronze, silver, gold, titanium, and platinum.

The higher the efficiency, the higher the price. However, the one thing that most people forget is to check whether the power supply unit they are buying is modular or not.

Now what is a modular power supply unit, you might ask? That certainly is a good question.

A modular power supply unit is the one comes with detachable cables. Which means that everything ranging from your 24-pin to your EPS as well as PCI-e and peripheral cables can be disconnected from the main unit.

These power supplies are normally more expensive since if you do not want the default cables, you can even invest in custom cables to mix and match your PC’s color scheme.

Additionally, you will find non-modular power supplies that come with all the cables attached to the unit itself, and then there are semi-modular power supplies; these have the 24-pin ATX cable, and the EPS cable coming out from the unit, and the rest of the cables are modular.

Now we must point out that having a modular power supply does not give you performance benefits at all. Although, the modularity feature is something that is linked with the higher end, top tier power supplies. So, they are correlated in some way.

At the same time, it does not mean that the modular power supplies do not come with their own set of benefits. As a matter of fact, there are a number of them.

Benefits of a Modular Power Supply Unit

Now for a lot of people, the benefits of a modular power supply unit are few and far between. People mainly stay away because of the added cost. However, the good news is that you are not only getting a power supply that is modular, but higher efficiency, and has longer warranty as well.

As for now, we are mainly sticking to some major benefits of having a modular power supply. Hopefully, this will remove some confusion for people who are not sure if they want to spend money on this type of power supply.

Less Clutter

If you are not the PC building expert that you see on the internet, then there are chances that you do not know how to properly manage cables, and in most cases, you leave a rat’s nest once you are done. The good thing about a modular power supply is that you do not have to worry about any clutter. Since you are only going to use the cables that you need to connect.

Easier Cable Management

This point ties into the first point that we have made. With a modular power supply, cable management becomes a lot easier than you might think. You do not have to worry about managing all the cables since you are only going to use the cables that you are actually going to use.

Full Custom Cables

On a non-modular or semi-modular cables, you are stuck with custom sleeved cable extensions, and while they look just as good, they only add more length to the cables themselves. So, if you have a relatively smaller case, managing the cables is going to require extra effort.

However, with a fully modular power supply, you can just buy full custom cables. They are sleeved across the entire cable’s length, there are some amazing color options available, and they can really make your PC look good.

Improved Performance

This is something that is not directly associated with modular power supplies but it is important to note down. You see, modular power supplies are usually the top tier power supplies that are available in the market.

They mostly come with 80+ Silver and above efficiency. So, generally, this means that the overall performance as far as the efficiency is concerned is going to be better as well.

This is a thing that most PC builders completely overlook.

Longer Warranty

Another benefit that you will be getting from investing in a modular power supply is that you will be getting longer warranties out of them. For instance, the Corsair RMx and RMi lineup of power supplies come with 10 years of warranty.

The reason for having longer warranties is that these companies have faith in the product, and are fully aware of the fact that despite extended performances, these power supply units will not be giving up on the users any time soon.


In conclusion, the only thing that we can say here is that modular power supplies are the way to go. Especially if you have the budget for them, these power supply units are hard to beat.

They are efficient, they perform really well, you get longer warranties, you have the option to customize the cables, and most importantly, these power supply units allow you to manage the cables with great efficiency as well.

All in all, buying a modular power supply is definitely a smart idea.

With the help of this article, we not only went through the benefits of this type of power supply but we also shed light on just what exactly is this type of power supply so the readers can have a proper understanding, and have an easier time making their decision
