The best power supply models for a computer in 2022

During the assembly of the system unit, among all the components, special attention must be paid to the power supply. After all, if this component is of poor quality, then all the others can fly - the motherboard, video card, RAM and others, since during power outages, power surges or short circuits, not only the power supply fails, but also its distribution circuits loads. Therefore, the quality and durability of the entire system will depend on the correct choice of this particular part. In order to make it easier for you to make a 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 margin from the largest total in the entire system of at least 25%. The most optimal is a margin of up to 50%. This means that for a computer with one video adapter, but intended, including for games, acceptable power will be approximately 550 to 750 watts. PSUs with a lower rating 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 functions. 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 PSU with an efficiency above 80%. Determined according to the certification system:

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

• Components. It is very important to evaluate the quality of components before buying: converters, capacitors and other circuitry elements. This affects the longevity of your computer.
• 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 presence of high-capacity capacitors at the PSU input, so it is better to purchase PSUs that have this parameter available.
• Noise and cooling. Now you won’t surprise anyone with a quiet PC, 120 mm or 140 mm coolers are present in almost all modern power supplies.Thanks to the large blades, they capture a lot of air and at the same time do not slow down, thus making the computer work almost silently.

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 been leaders 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 high quality, but also by quite reasonable cost. The power supplies deliver good power and are capable of running multiple graphics cards. In addition, the highest build quality and reliable fan operation are noted, which is guaranteed to ensure a 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. Popular models of this brand are quiet in operation and clearly control 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 brand 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.
