Modular Vs Semi Vs Non-Modular PSUs: Which To Choose

Things can usually get complicated when you find yourself constructing a PC. For instance, selecting the best PSU modularity. The time period ‘modularity’ right here refers back to the flexibility of attaching or detaching the cables based mostly on the consumer’s necessities.

Although modularity has nothing to do with the working mechanism of a PSU, selecting the best one will all the time assist enhance the high quality of the construct.

There are three varieties of modularities a PSU affords—modular, semi-modular, and non-modular. While modular PSUs will let you detach all of the cables, this isn’t doable for those who go for a non-modular one.

But after we are referring to semi-modular PSUs, they do supply customization, however solely as much as some extent. To be more exact, you can’t detach the motherboard and CPU energy cable.

In this text, I’ll break down the variations between the three varieties of modularities together with their professionals and cons. By the top, I’ll make sure that you’ll have an in depth understanding of every of them. Without additional delay, let’s soar proper in.

What is a Modular PSU

Modular PSUs are these PSUs that provide a removable cable setup. Meaning, you’ll be able to plug in solely essentially the most required (24-pin ATX motherboard energy cable and 12V CPU energy cable) wanted to function a PC and unplug the remaining ones.

Suppose you’re operating a PC with no graphics card and an NVMe SSD. In such a case, you’ll be able to let go of the PCIe and SATA energy cables out of your PSU. This means, you gained’t have pointless cables messing round.

Below I’ve listed some professionals and cons of a modular PSU for higher evaluation.

What is a Semi Modular PSU

An fascinating truth about semi-modular PSUs is that they have already got a few cables hooked up to them. As you may need guessed, I’m significantly referring to 24-pin ATX and 12V CPU cables. Some of the semi-modular PSUs also have a pre-attached PCIe cable for connecting a graphics card.

Apart from them, you’ll be able to add or take away different cables as you want. While these PSUs aren’t absolutely customizable just like the modular ones, they do supply flexibility to some extent.

What is a Non Modular PSU

Unlike the previous two, non-modular PSUs keep all of the cables hooked up to them, whether or not or not they’re getting used. You can’t detach them as with modular or semi-modular ones. But sure, you’ll be able to undoubtedly unplug the AC wire although.

Jokes aside, now let’s see how the non-modular PSUs could smash the aesthetics of your construct. Assume that your PSU has three PCIe cables hooked up to them. However, in case your PC makes use of a single GPU, as generally, you’ll be able to’t detach the remaining two cables.

They will solely occupy area inside your PC case and make it aesthetically unappealing. Further, the cable litter might additionally prohibit the airflow contained in the case, resulting in thermal throttling in the long term.

Modular Vs Semi Modular Vs Non Modular PSU

No matter the modularity of a PSU, its sole objective is to transform the AC energy from the wall outlet to the DC energy that your PC parts can use.

However, there are just a few variations between the three modularities. Here, I’ll cowl the foremost ones that ought to show you how to determine the most effective PSU in your construct.

Ease of Installation

Non-modular PSUs are a lot simpler to put in in comparison with the modular and semi-modular ones. Since they have already got cables hooked up to them, you don’t require extra effort to attach them.

Having stated that, it doesn’t essentially imply that modular and semi-modular PSUs are tedious to put in. These PSUs have a transparent tags that can assist you join them effortlessly. For instance, you’ll be able to see the labels in my absolutely modular EVGA Supernova 550 G3 PSU beneath.

It embeds a transparent MB label for connecting the 24-pin ATX cable that powers up the motherboard. Similarly, a CPU1 label to point the 12V CPU energy cable socket, and a VGA label for connecting a GPU.

Not solely have they got labels on the PSU, however on the connectors too. This makes it simpler to tell apart the fitting cable in your element.

However, you may discover it difficult and time-consuming to put in a non-modular PSU. In truth, a bunch of unused tangling cables may even be annoying.

Cable Management and Aesthetics

As mentioned earlier, non-modular PSUs have a bunch of cables soldered to them that may not be essential in your system configuration.

For instance, when you have not put in a devoted GPU or the PC case doesn’t embody a CD/DVD drive, you may wish to detach all of the PCIe and MOLEX cables. Unfortunately, you’ll be able to’t do this!

Those unused cables will solely make cable administration a nightmare. While you will have the choice to tie them up using a zipper tie or Velcro, it could nonetheless interrupt the airflow contained in the PC housing.

On the opposite hand, modular PSUs look higher within the first place. It helps you to detach each cable, even the essential ones like a 24-pin ATX and 12V CPU cable that are important for powering up the PC.

Similarly, airflow is all the time higher when there are fewer cables contained in the PC case. So, the system with modular or semi-modular PSUs has higher cooling than one with non-modular ones.

When it involves aesthetics, I don’t suppose I would like to elucidate it additional. The much less the cable litter, the more aesthetically pleasing your PC case will look.

However, you must have a correct concept of routing the cables. Otherwise, the cable administration will all the time look poor irrespective of whether or not you utilize a modular, semi-modular, or non-modular PSU.

Cable Replacement

If you will have a non-modular PSU and encounter any faults within the cables, you’ll have to interchange your complete PSU unit. However, this isn’t the case with modular or semi-modular ones. Simply substitute the unhealthy cables and try to be good to go.

While you might be changing the cables, be sure you use solely those out of your PSU producer. Otherwise, you could encounter connector compatibility points as a result of distinction in pinouts.

Price Range

Now that you’re right here, you may need already discovered which PSU is the costliest one.

The more customization and comfort, the upper the value tag. So, it will be a no brainer to state that modular PSUs are costly. Following the modular ones, semi-modular PSUs come second within the record of pricing.

On the opposite hand, non-modular PSUs are the most affordable amongst all three and higher for a price range construct. Although cheaper, they arrive at the price of poor cable administration and poor aesthetics and are by some means much less dependable than the remainder of the variants.

If you might be low on a price range, the non-modular variant may be the most suitable choice for you. However, don’t accept one that’s too low-cost. They usually use low-quality parts that don’t present safety towards over voltage, beneath voltage, or brief circuit, in the end posing a danger to different essential parts of your PC.

Verdict – Modular Vs Semi Modular Vs Non Modular PSU

The alternative between modular, semi-modular, or non-modular PSU completely relies upon upon your price range and preferences.

Modular ones are for fanatic PC builders who wish to construct a PC with full customization. Semi-modular for mainstream customers who’re on a price range, however search higher cable administration and personalization. And the non-modular ones for many who are comparatively on a low price range.

Revising the variations we mentioned earlier, semi-modular PSUs may be the most effective worth for cash. It will show you how to obtain a stability between the value of a non-modular PSU and the customizations supplied by a modular PSU.
