Best PC power supplies for 2020

The power supply is the main component that is necessary for the stable operation of a personal computer. The main function is to convert the voltage of 220 V into the required values ​​(3.3-12 V) to power the motherboard, processor, video card, etc. On the forums there are frequent problems with this device, for someone it fails after a month or a year and takes with it almost all or most of the components. Such problems happen for one reason - the wrong choice. After all, some users do not pay due attention to the purchase or even purchase this product from their hands. In order for the computer to work properly and for a long time, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best power supplies for 2020.

Purpose of this device

The first thing a person should understand is to understand what voltages the power supply gives and for what purposes they are needed. All power supplies have 3 lines:

• +3.3 V. It is necessary to power the motherboard, RAM, and output stages.
• +5 V. Designed to power PCI-E as well as IDE.
• The last line is 12 V. It supplies the voltage to the central processor and video card. There shouldn't be any losses. However, this can only be checked with a special tester. There are often cases when all lines are in good order, except for this one, so you should pay special attention to it.

In most of the design, the 3.3 V supply comes from the same winding as the 5 V. Therefore, some manufacturers indicate the total power. Due to the fact that these lines are not loaded up to 100% (except if a person installs several solid state drives or hard drives per terabyte), there is no problem with them. Therefore, it is not necessary to focus only on them, especially when a power supply unit is bought from a store, if with hands, then it is still necessary to check.

The main line in this device is 12 V. It is loaded almost to 100%. After all, it powers the central processor, which, depending on the modification, can require from 50 to 150 W, as well as a video card, which requires twice as much power. When choosing a power supply, it is important to look at the total power along this line so that the computer can start up.

The second thing to pay attention to is the connectors. This is a mandatory requirement, especially when the user has a powerful video card that requires two 6 pin connectors. Whereas the purchased device may have only one and the same 8 pin. In order not to get into such a situation, this is taken into account in advance. You should not pay special attention to the main power supply (20 + 4 pin), which is connected to the motherboard, it is enough to check the integrity of the contacts. Next comes the power supply to the processor, which can be either 4 or 8 pin. In some cases, two 8 pins are required, but this is only found in very powerful devices. It is important to understand that if a person buys a power supply and there is only one 8 pin cable for the CPU, but there is a second cable for the video card, then it is prohibited to install its connector for powering the CPU.

Some video cards do not require additional power, for example, products with a capacity of up to 75W Because they are able to function properly through the PCI-E slot. In more powerful modifications, the presence of an auxiliary source is required. It is important to make sure that all cables are present, you can even take it with a margin if you plan to upgrade the system.Just remember that in this case the person will overpay a little.

To power peripheral devices and drives, a special SATA connector is used, which is connected to the motherboard and the corresponding device. No pins are provided here. The main thing is to ensure that the PSU has the required number of connectors. If the user bought a power supply, and then found that there is no additional connector for a video card, then a Molex adapter is bought. This is a suitable solution, but it is rarely found, since most of the manufacturers produce devices with all the necessary cables.

The size of the power supply unit is selected for the features of the case, but the opposite situation is also allowed. There are also standard ATX versions on the market, which are suitable for almost every computer. Compact models are not focused on small systems.

Auxiliary function to ensure safety

Every year manufacturers release more powerful power supplies that are able to work with multiple video cards and two processors without any problems. However, the wires in the sockets remain the same and do not change. Therefore, impulse noise may occur, this phenomenon is quite common. Power Factor Correction (PFC) has been developed to prevent early damage to the instrument and components.

The system is a powerful choke that is installed immediately after the rectifier up to the first filter capacitors. The main purpose of the product is to limit the charge current. In practice, it looks like this, if you turn on the power supply without this element, then the person will hear a click, there are no harmful consequences in this. A sound occurs due to the fact that in the first milliseconds the product consumes many times more energy than indicated in the technical data sheet, which leads to sparking. If this module is installed, then it extinguishes all interference not only from the outlet, but also from some capacitors inside the system unit itself.

Correct power calculation

After studying the theoretical part, the user needs to find a good PSU that fits his system. This process is easy, you can do all the calculations yourself, which will take a lot of time, or use a special calculator that is present on many thematic sites. All that is required is to enter the name of the processor, video card, RAM, hard drives, the number of cooling fans and how long you plan to use the computer per day.

Depending on the result obtained, the appropriate equipment is selected. There is an important point here - it is not recommended to buy a power supply end-to-end. For example, if the maximum load turns out to be about 550 W, then it is best to buy a 750 W product, the computer will not make much noise, which will create a comfortable environment. If a quiet system is created, then the power must be even higher.

What to look for when choosing?

For a correct purchase, remember:

• It is not recommended to use the built-in power supply unit designed for 650 W. 90% of these products do not have PFCs, which can lead to negative consequences if a power surge occurs. When this happens, at best the user will only need to replace the power supply unit, at worst some components, starting with RAM and ending with a CPU or video card.
• It is important to understand that if 650 W is indicated on the power supply, this does not mean that it can really give that amount of energy. There is a deviation from the nominal value and it is found in almost all products, somewhere more, and somewhere less. You should not buy a product where voltages less than 11.5 V are supplied through the 12 V line, this will negatively affect the main components of the PC.
• Active PFC is one of the main criteria for long lasting and reliable performance. It is also recommended that you pay attention to the various certifications that ensure that only tested and reliable radio components are placed inside the product.
• In some cases, video card manufacturers indicate the recommended power supply unit on the box, which is very different from the actual requirements. For example, a video card can consume only 100 W, and the manufacturer recommends installing a 600 W PSU. This is done to reassure the company that produces the graphics device. The manufacturer deliberately inflates the readings so that he would not have problems if the user uses less powerful devices.
• For a quiet assembly, it is recommended to buy equipment that will be 2 times more powerful than the nominal requirements. This way the system will not be heavily loaded, so the fans will not bring discomfort. However, in this case, there is a high overpayment, this should also be remembered.

Following all the described criteria, a person can easily find a suitable device for his computer. At the same time, the price of the products is different, sometimes you can find a quality option for 1,000 rubles, and sometimes you cannot find a normal power supply even for 4-5 thousand rubles. The main thing is to read reviews or see a selection of the best power supplies.
