Full vs. Semi vs. Non-Modular Power Supplies and What’s the differences???

Full vs. Semi vs. Non-Modular Power Supplies

Today we are talking about Full vs. Semi vs. Non-Modular Power Supplies and what the difference is between that are If you are building a new pc and the time has come to decide on a power supply we hope you didn’t plan to skimp out here since having a few dollars off the PSUs can end up costing you way more down the line not only will a higher quality unit offer better power efficiency and therefore a rack up a slightly lower electrical bill it also won’t run the risk of potentially frying all of your expensive hardware.

However, we’d like to turn our attention to one aspect of power supplies that don’t get as much attention.PSU has come in three flavors when it comes to modularity non-modular semi-modular and fully modular each one has its own pros and cons and we’ll cover all of them in this blog so without any further ado let’s begin.

Briefly Explain What is the power supply or PSUs?

An power supply is an electronic device that provides electrical energy to an electric load the main function of an electric supply is to convert one form of electrical energy to another end because the resultant power supply is sometimes referred to as an electrical supply which is unusually stand-alone devices while others are built into large devices along with their load example. All found in desktop computers and consumer electronics devices.

For each power supply it is necessary to provide its load as well as to utilize any energy from its design depending on the energy source while performing this task. An electrical supply can obtain energy from a variety of energy source in which electrical energy conversion system energy storage devices such as batteries and fuel cells electrical mechanical system such as generator and alternating solar energy converters or any other electrical supply is a power input in all electrical supply that receives energy from the energy source and is the power output that provides energy to the load.

Most power supply consists of electrical input and output electrical connector or hard wired circuit connection although some power supply employs wireless energy transfer rather than a galvanic connection for electrical input or output. Some power supply also has other types of inputs and output such as external supervision and control for the function.


What is Modularity

First, a brief overview of modularity itself a module is defined as a set of standardized parts or independent units that can be used to construct a more complex structure its a broad definition that encompasses standard house plaything toys and everything in between however within the context of power provides modularity refers to the Cables.

Namely, will the cables be swapped out or are not they inbuilt absolutely standard and semi-modular PSUs may be customized to varying degrees within the former case all of the cables may be removed or replaced whereas within the latter thus just some go with these standard options, therefore, the name, however, the cables on a non-modular PSU ar all soldered to the unit allowing zero customizability as you’ll guess this is still bound implications computer builders ought to understand each aesthetic and sensible so let’s get through all 3 varieties and see what each has got to offer?

What are Non-Modular Power Supplies?

The main benefit of non-modular PSUs is the price since all the cables that you could possibly need permanently attached to it non-modular power supplies are cheaper to manufacturer it’s important to note that this is not a matter of quality.

A non-modular power supply is not necessarily less reliable than its semi-modular and fully modular siblings it’s just more cumbersome and since some of the many cables attached to the unit simply aren’t going to find any use you Will be left with quite a cable clutter on your hands.

At its core, cable management is an aesthetic issue but having lots of cables clogging up the case can seriously impede the airflow so it’s not all about the looks. your cooling system could end up working worse than expected simply due to the cable clutter still this doesn’t mean that the non-modular power supply is all bad.

Full vs. Semi vs. Non-Modular Power Supplies

Novice builders area unit sure to appreciate them for his or her easy use since all the cables can already be properly hooked up they will have less bother connecting everything no have to be compelled to discover what goes wherever on each end and if you have a bigger case ideally one with many spaces for cable management then you’ll be able to even use a nonmodular PSU with a clear case and nobody are going to be the wiser.

Bigger cases generally tend to cost more money but non-modular power supplies have the benefits of being the cheapest power supplies around so the price really evens out either way, this is the case and the power supply combination we suggest to most novice builders mostly those on a budget.

What are Semi-Modular Power Supplies?

Semi-modular power supply strike a fine balance between the approachable price of non-modular units and the aesthetic appeal and customizability of fully modular units they typically come with at least the 24 pin connector permanently attached with some models also giving the PSI express in the 8 pin CPU cables the same treatment, the other cables can all be removed or replaced so why are semi-modular PSUs so popular?

Well the great thing about them is that they offer all of the modularity most people will need not to suffer from clogged cable all the cables that come connected to the power supply via just the 24 pins connector or the PCI Express and 8 pin CPU cables as well our cables that you will definitely use. so if you don’t go fully modular you won’t have any cables dangling around for no apparent reason.

Semi-Modular Power Supplies?

Now as we’ve said you can get away with non-modular units if you’re building inside a larger case without too many issues it’s even a great way to save some bucks but if you’re using a smaller case well then you’ll definitely want the benefits of modularity on your side it’s easier to fit everything into place when there are no unwanted cables hindering our progress, so if you’re are building inside a micro ATX case we thoroughly suggest getting a semi-modular PSU.

What are Fully-Modular Power Supplies?

Now you Might be asking yourself but wait if the semi-modular power supplies are all that great both in term of price and functionality why anyone even bothers with fully modular units and honestly the answer boils down to just the looks 99% of the time so if you’re looking for a PSU that will look great perform great and not block the airflow in any way all in an acceptable price then you don’t need to bother with fully modular units.

The semi-modular ones offer everything you will ever need but if it’s all about the looks and you have plans to build the ultimate transparent case pc where cables will not only be something to hide but additional features and the full modular units are for you since you can replace all wires you can start to tinker with custom watercolors and not just a color you get to decide on the cable length- this opens up a whole new avenue when it comes to.

Fully-Modular Power Supplies

Planning out the aesthetics of your build but adds you’d expect this comes at a price on their own fully modular units aren’t that much more expensive than semi-modular ones but once you start adding custom cables to the mix all of which are purchased separately the overall price Starts to skyrocket so for most people the cables only really boils down to non-modular and semi-modular.

Fully Modular units are just too much of an overkill for anyone not looking to take full advantage of the opportunities they present namely customizing the cable color and length. the only practical reason to get a fully modular unit is if you’re building a mini ITX gaming PC or the modularity and custom cable lengths will really help out with the cramped space.


In this blog, we summarize the modularity of the power supply whether cables are permanently connected to units or not. All cables in non-modular units are permanently connected and thus they have to come up with all the cables that you could ever need as a result of which most of the inactive cable is not random. Semi-modular units offer the best of both the world in which you are bound to leave all the cables that you are bound to attach permanently but offer an option for modularity with rest and fully modular units that can remove or replace all their cables if you plan on good use of custom cables only really need. visit robinguide.com
