Modular power supplies are a must-have for custom PC builders. It doesn't matter if you are a PC enthusiast wanting to build your dream PC. Or just a gamer who wants to play with the best components for a flawless gaming experience, a modular power supply is something you should NEVER compromise on.

A modular power supply is a type of power supply that is specifically designed for users to make their work easier. With this type of power supply, the cables and connectors are detachable, making the installation and management process much more convenient.

However, this isn't the only reason for a custom PC builder to get a modular power supply. There is a list of benefits for custom PC builders, and in this article, we will cover the top benefits for you. So without further ado, let's get started!

1. Offers Convenient Cable Management

If you are someone who likes to keep everything managed, then here's a solid reason for you to go with the modular power supply. A traditional power supply consumes a lot of space inside the computer case. 

However, with the modular power supply, you can add the components of your PC and plug in the modular cables you need. This typically saves your PC case from overflowing with wires, and now you can have fewer cables (typically 1.5 meters less wires) in your case. Overall, this saves you time as you don't have to make too much effort managing your cables. 

However, getting a modular power supply isn't the best option if you already own a high-end case offering premium cable management. But it is undoubtedly one of the cheapest ways to keep your interior neat and cope with aesthetics. 

Furthermore, now that you have your cables managed, you can feel free to work on the looks of your PC. With no wires tangling in your case, you are now adding LED lights to make your PC case more aesthetically pleasing. Modular power supplies also allow users to have custom cables if they want to.

2. Better Managed Cables Lead To Better Power Flow

If you are a custom PC builder willing to build a high-end gaming rig, then a modular power supply is a better option to go with. Modular PSUs ensure that they provide better power flow through all the computer components. 

The modular connectors allow the PSU and PC components to connect uninterruptedly. These modular connectors enable more efficient power transfers that won’t bottleneck your PC’s performance, ensuring you can enjoy the best games without system lag.

3. Systems With Modular PSU Have Lower Temperatures

Another edge that a modular power supply gives to your PC is that it lowers the temperature. Since a modular power supply has fewer connectors and power cables, the chances of them clogging up inside your PC case are comparatively low, and the overall airflow in your computer case increases.

In general, modular power supplies deliver better continuous performance than non-modular power supplies because modular ones don't hold as much heat in them as a non-modular power supply would. Modular power supplies help keep the overall operating temperature low; this increases your system's reliability and stability and reduces overall power consumption.

4. Modular PSUs Are Perfect For Small Form Factor Cases

If you are a fan of small form factor cases like the Mini-ITX cases, then a Modular PSU is a blessing. The small form factor cases are limited to space, but worse is that these also tend to have limited cable management features. 

You won't find any holder to route and hide cables in such small cases. These cases also lack specialized spaces and gaps as well. Since everything is so small and packed together, one can use a modular PSU to free up some space in the PC case. 

5. They Are Easier To Clean

Another benefit of choosing a modular PSU over any other type of PSU is that modular ones are easier to clean. With the modular PSU, you don't have to go through the tedious process of removing a stiff 20 or 24-pin connector and then clean. Instead, you can disconnect the PSU side of the cable.

The modular power supply also keeps the tower case (if you have one) uncluttered and clean. Many modular PSUs have intake fans that pull clean air directly into the unit; this way, you don't have to worry about dust, and you will always have a cleaner PC.

6. You Have Easy Access To All Your PC Components 

Being a custom PC builder is not easy. You have to attach all the different components of your PC while building it, and if a component isn't working, you might as well want to detach it and get a replacement. Accessing each component one by one is time-consuming and can get frustrating.

However, with a modular PSU, you can have much easier access to all the components at once, and the best part is that you don't have to remove the wires before accessing the components. This can be useful when changing or adding components while the system is running.

7. You Can Remove Or Replace The PSU With Convenience

One of the silent benefits that most PC builders won't discuss is this. People rarely talk about this benefit, but it's worth mentioning. It doesn't matter if you are replacing a faulty power supply or just removing it for your routine clean-up, uninstalling a modular PSU is a piece of cake. 

For a modular PSU, all you have to do is detach the power connectors from the unit and unscrew it from the computer case, and that's all. The power cables can still stay connected to the different components of the PC. You can clean the components and put the PSU back in its place without hassle.

In comparison, if you want to remove a regular power supply unit, you must unplug all the power connectors' internal components. This means you can disconnect optical drives, motherboard, hard drives, graphic cards, case fans, and everything else, all one by one. In this process, you would also have to deal with the cables and manage them again once you put the PSU back. 


There are several benefits of getting a modular PSU. However, it all comes down to the type of PC build you are looking for and your budget. A modular PSU is slightly higher in price than other types of PSUs that you can buy, but its benefits are worth it.
