POWER SUPPLY  What is it? + Types and Functions ▷ 2020

The power supply It is an essential element that you must have on your computer in perfect condition. This is because the function it fulfills is so important that it could burn the motherboard or any other hardware.

But Keeping it in perfect condition is not the only thing you should do, you should also know how it works and what are the characteristics it has.

If you want to know how to choose a power supply, we invite you to continue reading. Further, we will show you the different types that exist today and how you can calculate the best model for your computer.

What is a power supply and what is this component for?

The power supply is a hardware that is inside the box of our PC and serves to transform the electric power. Its task is to convert the alternating current, which comes from the home, into a direct current so that it can power the different electronic circuits that exist on the boards, or computer bus, that make up the computer.

In this way, the different components receive the voltage required according to manufacturer’s specifications. In addition, some models include protection against a rise or fall of electrical voltage that can be done at home.

Types of power supplies How are these hardware classified?

There are different types of feeding that you can find on a computer.

We will show you each of them below:

  • Linear: are characterized by work online. They take care of reduce the voltage, then convert it to the voltage that corresponds and the filtering wave to finish in the maintenance that the voltage must have for the output. This is necessary for you to do because of the different variations that are made in the entry of the stream.
  • Commutative: they are more efficient than the previous model. So they are used more when needed work with a low cost and compact design. Your task is convert energy by means of a commutative function.

We can also classify these components according to the format they present. In this way, you can get different sizes and connectors that can be used in different models of computers.

Next, we will present the types of power supplies most used today:

  • AT: has two connectors, with 6 pin each and connect directly to the motherboard. They had the disadvantage that connectors 8 and 9 were similar and if they were connected in the wrong way they could burn motherboard. This model is not widely used today.
  • ATX: is the power supply that replaces the previous model. It has 24 pin and they have a measurement of 15 cm wide by 8.6 high. Today it is one of the most popular.
  • SFX: when you need hardware that can go into compact equipment, this model is ideal. This is because its dimensions allow it to fit into thin devices, you can count on a powerful fan and reach a capacity that can reach up to 700 W.
  • TFX: It is not one of the most used due to its elongated design in which it cannot be installed in any box.

What is the function of a power source in a computer?

The functions that power supplies have in a computer are those that we will show you below:

  • Transformation: The first thing a power supply must do is convert the alternating current from 230 volts (or 120 in some countries) that comes from home to a voltage between 5 and 12 volts. This will be done by means of a coil which is covered with copper wires.
  • Rectification: as there are curves in the process of alternating current, it is necessary to prevent these oscillations so that the voltage is maintained constant during the time it is inside the fountain. This will prevent it from exceeding 12, but also not that it falls below 0.
  • Filtration: through capacitors that retain the Energy and they let it pass very slowly so that the voltage can be kept as stable as possible.
  • Stabilization: It is the last stage that the power supply has. Once the stream meets rectified (for having a continuous voltage) and is flattened (because it has been filtered through the capacitors), it is necessary to stabilize it so that the components receive direct current and manage to work without variations or the possibility of burning.

How do I know which power supply my computer needs according to its performance?

To know what power source your computer needs you must first know the technical requirement that has.

To do this, you must carry out the following steps:

  • Go to browser from your computer and open the page OuterVision. “www.outervision.com”
  • Search the eyelash
  • In Base plate choose Desk.
  • Then find the UPC brand and socket.
  • Then, you must choose the processor and the amount you have. To do this you will have to look for it by displaying the menu in which all the available models will appear.
  • Select option 90% TDP (recommended).
  • In the countryside Memory, you must select the type of memory RAM you have and choose the modules of it. When you have found the model, you must enter the amount you have of this hardware.
  • Go to Video Card – Group 1 and choose the model and brand.
  • Address the group Storage. Select the amount and type of disc you have.
  • You should do the same for the optical drives, PCI Express cards, PCI cards, liquid cooling, and liquid cooling pump.
  • If you have other elements on the PC, you must add it in the option Other devices (USB, LEDs, controllers, etc.).
  • Finally, you must choose the hours per day that you will use the computer.
  • When you have finished you will have to click on the option Calculate.

A report will appear in which you will have the amount of voltage and power you will need.

If you prefer, the tool will recommend the type of power supply that suits these needs. In case you do not want to do it by this means, you must search in Google or in specialized stores what is the best tool for your technical requirements.
