The best power supplies for your computer in 2020

During the assembly of the system unit among all the components, special attention must be paid to the power supply unit. After all, if this component is of poor quality, then all the rest can fly - the motherboard, video card, RAM and others, since during power outages, voltage surges or short circuits, not only the power supply fails, but also its distribution circuits load. Therefore, the quality and durability of the entire system will depend on the correct choice of this particular part. To make it easier for you to make your choice, we have compiled a rating of the best power supplies for computers.

How to choose

It is generally accepted that the most important characteristic when choosing a power supply is its power, but in fact the list of selection criteria is much wider:

• Power. There should be a power reserve of at least 25% of the highest total in the entire system. The most optimal margin is up to 50%. This means that for a computer with one video adapter, but intended, including for games, the acceptable power will be approximately 550 to 750 watts. PSUs with a lower rate are suitable for systems in which there is no video card at all or it is very weak.
• Efficiency and certificates. This indicator determines how efficiently the device is functioning. Higher - ensures that the amount of power from the network is as close as possible to that given by the computer components. For systems operating at an indicator of 500 W or more, it is better to take a power supply unit with an efficiency higher than 80%. Determined according to the certification system:

1. Certificate 80+;
2. 80+ Bronze certificate;
3. 80+ Silver certificate;
4. 80+ Gold certificate;
5. 80+ Platinum certificate;
6. 80+ Titanium certified.

• Components. It is very important to evaluate the quality of components before buying: converters, capacitors and other circuitry elements. The longevity of the computer service depends on this.
• PFC. The functionality of the system is aimed at reducing the phase shift, which is almost impossible to avoid in AC networks due to the fact that there are high-capacity capacitors at the input of the power supply unit, therefore it is better to purchase power supply units that have this parameter available.
• Noise and cooling. Nowadays you won't surprise anyone with quiet PCs, 120 mm or 140 mm coolers are present in almost all modern power supplies. Thanks to the large blades, they trap a lot of air without slowing down, making the computer virtually silent.

Which company is better

Today, there are quite a few brands offering power supplies for computers. Therefore, the competition in this segment is very high, however, the best manufacturers have long held leading positions in the market and offer a reliable, high-quality product. These include:

• Corsair. The popularity of the models of this company is explained not only by the high quality, but also by the quite acceptable cost.The power supplies deliver good power and are capable of handling multiple graphics cards. In addition, the highest build quality and reliable fan operation are noted, which are guaranteed to ensure stable and durable computer service.
• Thermaltake. The power supplies of this brand have high-performance parameters that can withstand heavy loads on the power grid. There is also a powerful cooling system and the most reliable protection. The popular models of this brand are distinguished by their quiet operation and precise control of the flow of electricity, which does not allow the influence of drops and loads on the operation of the system.
• FSP Group. The main feature of this company is that it produces only power supplies, which differs from most competitors. Therefore, all the brand's developments are aimed at continuous improvement of the device components, while the company is a supplier of budget models, which does not affect the quality in any way.
