what is a modular power supply?

Wondering what a modular power supply is, and how they differ from their non-modular counterparts? You've come to the right place. Here at Bravo Electro, we're the experts in all things power supply. We're going to break it down in laymans terms to help you gain an in-depth understanding of how this style varies from others and when you may need one. In this article, we're going to explain everything there is to know about modular power supplies. We'll start by answering the question "what is a modular power supply?" in simple terms that anyone can understand.

Then, we'll talk about why modular power supplies are essential, and explain the different situations where they're necessary. Finally, we'll discuss the pros and cons of modular power supplies, and help you pick the right one for your needs. At the very end, we'll recommend the #1 place you can find all your modular power supply essentials - so stick around for that! Let's get started with the main question you came here with today:

What Is A Modular Power Supply?

A modular power supply is a type of unit that gets its name from the fact that it has several removable cables. The "modules" in question are the various parts of the PSU that can be added or removed as needed. This flexibility is one of the main advantages of modular PSUs since you're able to add or remove cables based on your needs - which we'll talk about more later.

Now that we've answered the question "what is a modular power supply?" let's move on to explaining why they're essential, and some of the situations where you may need one.

What Is A Modular Power Supply Used For?

As we briefly touched on before, modularity is one of the key advantages of this style over non-modular PSUs. When you're not using all of the cables that come with your unit, they can just be removed - which helps keep things tidy and organized inside your computer case. This is especially helpful if you're tight on space, or if you want to improve airflow to help keep things cool.

Another advantage of modularity is that it allows you to custom-tailor your PSU to your needs. For example, if you're only using a few extra devices right now but may add more in the future, you can buy a modular PSU with enough "ports" (i.e., connectors) for your current needs and then buy additional cables later as needed.

This flexibility means that you don't have to pay for cables you're not using, and that you don't have to worry about having too few or too many cables later on. It also means that you can easily upgrade your PSU if you need more power in the future - something that's not always possible with non-modular PSUs.

There are a few other advantages of modular PSUs worth mentioning as well. For example, they tend to be easier to install since you're not dealing with a bunch of excess cables. And, they often come with longer warranties than non-modular units since manufacturers know they're built to last.

Now that we've talked about the advantages of modular power supplies, let's move on to discussing the different types so you can pick the right one for your needs.

The Two Main Types Of Modular Power Supplies (Fully Modular vs Semi-Modular)

There are two main types of modular PSUs: fully modular and semi-modular. As you might've guessed, fully modular units have all of their cables removable - while semi-modular units have some (usually the essential) cables hardwired in place.

What Is A Fully Modular Power Supply?

Fully modular PSUs offer the greatest flexibility since you can remove all of the cables when they're not needed. This is helpful if you want to improve airflow or if you're tight on space inside your computer case. It's also helpful if you plan on upgrading your PSU in the future since you won't have to worry about compatibility issues with new cables.

What Is A Semi-Modular Power Supply?

Semi-modular PSUs, on the other hand, tend to be more affordable since they don't have as many features. They're also generally easier to install since you don't have to deal with as many cables. And, they often come with longer warranties since manufacturers know they're built to last.

Which Is Right For You - Fully Modular vs Semi-Modular Power Supply

So, which type of modular PSU is right for you? If you want the greatest flexibility and are willing to pay a bit more for it, go with a fully modular unit. But if you're on a budget or if you don't think you'll need all of the extra cables, a semi-modular PSU will probably suffice.

How To Pick The Right Modular Power Supply For Your Needs

Now that we've gone over the different types of modular power supplies, it's time to talk about how to pick the right one for your needs. The first thing you need to do is determine how much power you'll need. This can be tricky, but a good rule of thumb is to add up the wattage requirements of all of the components you'll be using.

Once you have a rough idea of how much power you need, you can start looking at specific units. When doing so, pay attention to the following specs:

  • Wattage: Make sure the PSU has enough power for your needs. It's always better to err on the side of caution and get a unit that's more powerful than you think you need since you can always underclock or turn off components if necessary.
  • Efficiency: Look for a PSU with an 80 Plus efficiency rating of at least Bronze. This will help ensure that your unit is as efficient as possible, which is important both for performance and for saving money on your electric bill.
  • Modularity: As we mentioned earlier, fully modular units offer the greatest flexibility. But if you're on a budget, a semi-modular unit will probably suffice.
  • Connectors: Make sure the PSU has enough of the right connectors for all of your components. For example, if you have multiple graphics cards, you'll need more PCIe connectors than someone who only has one.
  • Form Factor: Ensure that the PSU will fit in your computer case. The most common form factors are ATX and SFX, but there are a few others to be aware of as well.
  • Price: Don't spend more than you need to, but don't cheap out either. A good quality PSU can last for years, so it's worth investing in a unit that will do the job right.

Once you've considered all of these factors, you should have a good idea of which modular power supply is right for you. Just remember to do your research and buy from a reputable manufacturer, and you'll be all set! Speaking of place, we know just the place to find all your modular power supply needs: Bravo Electro.
