We find many power supplies on the market, which makes our choice very difficult. Therefore, we have thought that it will be useful to know which are the best manufacturers of power supplies on the market in order to rule out options that may not be so good. Not everyone pays attention to this component, and it is vitally important in our team.
In all fields there is a manufacturer that offers a quality superior to that of its rivals, something that is complicated in computing. Here, the competition speaks for itself and all products have a weak point, but we are going to show you which is the best manufacturer of power supplies that you can find.

be quiet! The best silent fountains
The name of the brand gives us a clue to the added value of its products: silence. The company be quiet! It has been manufacturing cooling solutions, power supplies and PC cases for many years.
It has a well-deserved reputation for the low decibels that its components produce. As you know, active power supplies are usually components that do not take much care of this aspect because the objective is another: to be efficient, reliability and great power.
Many people think that passive or semi-passive sources are the best options to obtain a silent source. On the other hand, be quiet! is a highly reputable refrigeration manufacturer, and has already warned that the heat that this type of product gives off inside the box is not recommended.
So, their position was to not include any passive sources in their catalog to offer active sources as quiet and reliable as possible. In contrast, it introduced stopping systems on the fountain fan so that it only rotated when the load was higher, saving energy and increasing silence.
For this reason, if you are a person looking for a silent team, keep in mind be quiet! because very few brands offer systems as quiet as this one. To give you more weighty arguments, we recommend this model.

Best Modular Fonts: Corsair

It is true that we can find other options such as NZXT , Cooler Master or SilverStone , but Corsair takes the modular experience to another level . We can find semi-modular systems, like other modular ones that work really well. Also, mention the number of cables and replacements that we receive with the box when we buy a Corsair product.
Why did we choose Corsair? Basically, because of the customization options we have. There is the possibility of customizing the cables of the power supply in order to improve the appearance of the interior of our equipment.
In this way, it is possible to play with the ideal colors or themes, creating a total ecosystem inside and outside the PC. If we go to third-party stores that offer this possibility, you will see that the option with the most spare parts of all is Corsair . In fact, this manufacturer sells its own cables in its official store.
So, we consider it to be one of the best manufacturers of modular power supplies that we can find in the market. We propose a semi-modular option and a modular one .

The sources with the best energy certification: SeaSonic

There is no doubt that SeaSonic is one of the best power supply manufacturers in the world. On this occasion, we raise our claims with the idea of finding the most efficient source , or with the best energy certification on the market. This field is covered by SeaSonic sources with different powers, but none brings RGB lighting.

Best value for money power supplies: SilverStone

If we are on a tight budget and want the best source possible, consider SilverStone . As you have seen, each manufacturer looks like the best in certain aspects. Until now, SilverStone has not been recognized as one of the best, but the value for money of its products places it as one of the best manufacturers of power supplies in the world.
A good power supply should have good wattage , good certification, and semi-modular or modular options if possible. You will see that all this requires a lot of money, being a component that can range between € 70-120 perfectly.
As we know that not all of you can invest that amount of money, we have thought about focusing this section on sources that do not exceed € 70 and, in return, we obtain what we have said before.
We soon realize that energy certifications raise the price of the source a lot . We have looked for options in 500W and 650W , which are the most sought after and with the best value for money that exist. These are our proposals.
| Hardzone | SilverStone ET550-G 550W 80 Plus Gold |
|---|---|
| Continuous power | 550 W |
| Voltage (VAC) | 90 – 264 |
| Frequency (Hz) | 47 – 63 |
| Pfc | Active |
| Sound level | 18 dBA minimum |
| Energetic certification | 80 Plus Gold |
| Warranty | 5 years |
| Useful life | 100,000 to |
| Operating temperature | up to 40ºC |
| Dimensions | 150mm x 86mm x 140mm |
Best SFX Power Supplies: SilverStone
Do not forget another form factor widely used in more compact equipment: SFX . It is not a market in which we find a huge offer of models, so SilverStone stands out with the best catalog of SFX sources on the market.
In this case, perhaps, the brand with the best value for money is SilverStone because we find very valid models below € 100 . On the contrary, to enjoy an SFX source from other brands we have to exceed € 100.
These types of sources deserve your attention because they are widely used in Mini-ITX boxes or more compact solutions. Mounting a smaller form factor doesn’t mean equipping a PC with worse components. This translates to a certain power requirement, but only one SFX source can supply it to the team.
| Hardzone | SilverStone SX500 V2 SFX-L 500W 80 Plus Gold Modular |
|---|---|
| Continuous power | 500 watts |
| Form factor | SFX-L |
| Voltage (VAC) | 90 – 264 |
| Frequency (Hz) | 47 – 63 |
| Pfc | Active |
| Energetic certification | 80 Plus Gold |

| Warranty | 5 years |
| Useful life | 100,000 to |
| Operating temperature | up to 40ºC |
| Dimensions | 125mm x 63.5mm x 130mm |

Each manufacturer is specialized in certain aspects, so there is no clear best manufacturer of power supplies in general terms . On the other hand, we can see brands that offer better qualities than the rest, such as a more attractive price.
