Although these types are more expensive compared to the non-modular power supplies, the fact that they provide the best performance is what makes them a smart investment. While you can cable manage non-modular PSUs to eliminate some of the effects from the ‘nest’ of cables there are almost always unused cables that need to be stuffed somewhere and it’s generally a clumpy mess.īoth the semi-modular and the fully-modular power supplies allow the best airflow efficiency. These cables interrupt the flow of air and also attract dust which can lead to components overheating/ breaking quicker. Air FlowĪirflow is largely affected by non-modular power supplies due to the cables that stretch across your case from the power unit to the components. Going for a modular option gives you a bit more flexibility with your current build or future upgrades. Lastly, The more expensive fully-modular PSUs aren’t that much more expensive than the semi PSUs so if you can spare a bit more cash then always go for the modular option. The semi-modular PSUs offer a cheaper alternative to fully modular PSUs however the savings aren’t all that much and this is where your choice depends on your individual building needs. We clearly see that a non-modular power supply is the cheapest option with it costing nearly half as much as a fully modular PSU. Below is a table of EVGA’s 750W non-modular, semi-modular, and fully modular power supplies showing how the prices differ between types. Prices vary depending on the modularity of the power supply with non-modular PSUs often being the cheaper option. The lack of cables and the extra case space equate to lower temperatures and happier components.ĬHECK PRICE Pros and Cons of Modular, Semi-Modular, and non Modular PSU Price Thanks to the reduced amount of cables sat inside the case there will be less dust building up.You also won’t have a ‘nest’ sat in the middle of your case as only the cables you require will be used. Airflow is greatly increased thanks to better cable management flexibility and a few extra sockets to seat the cables into the PSU.The main benefits to a fully modular PSU are similar to the semi-modular PSUs: While this may be a good point, fully modular PSUs are still highly recommended and they are compatible with the different coloured power cables giving you a bit of extra design flair with your build. If your budget allows for it there are no negatives to a fully modular PSU and you may be wondering why bother going fully modular if you are going to plug those important cables in regardless?

Lastly, we have the fully modular power supply and as you expect all cables are individually seated. It is worth noting you cant use braided cables with a semi-modular PSU fully so bear this in mind if you are considering getting cable mods.įor the price, we are a big fan of this semi-modular PSU option:ĬHECK PRICE What is Fully Modular Power Supply? With these semi-modular PSUs, You don’t have to compromise too much on unused cables as you will be plugging in most of the important pre-attached cables. Semi-modular power supplies are a great way to save money on your new build. The 24pin and 8-pin CPU come pre-attached, while the PCIe and other cables come as modular.The 24pin and the PCIe come pre-attached while all your others come as modular.The 24pin comes pre-attached while the PCIe, 8pin CPU, and other cables come as modular.There are various types of semi-modular power supplies available: Think of a semi-modular PSU as a hybrid power supply with a mixture of attributes from the non and fully modular PSUs. Next to the dedicated cables, your SATA cables and sometimes an extra PCIe cable are your modular options. Semi-modular power supplies have your main cables, like the 24-pin, 8-pin CPU, and a PCIe cable all connected to one circuit board. There are a lot of non-modular power supplies out there but this one is our favorite:ĬHECK PRICE What is Semi-Modular Power Supply?Īs you may have been able to tell from the name, the semi-modular PSU has some but not all cables hardwired.
#VIPER SMPS DESIGN SOFTWARE WINDOWS#
If you are on a budget or are building a system in a case with no windows then a non-modular PSU is acceptable, however, be aware that the cables will gather dust and airflow inside will be negatively affected which can increase the stress on your components.
#VIPER SMPS DESIGN SOFTWARE PC#
If you are rocking the best PC case, the last thing you want is dust covered cables all over the place. These types of power supplies will often feature in budget builds and even though they still do an effective job at powering your system, the nest of cables is an eyesore. This speeds up manufacturing making these ugly components cheaper. Non-modular power supplies look and do the same as other power supplies except the cables are all soldered to one circuit board inside.
