The power supply is a very important component of a personal computer, which converts 220 V, going through the mains, into a voltage of 3.3 to 12 V - depending on the needs of a particular element. Many users are reckless about buying such a device, buying it with the case, so to speak, for change. However, if you plan to assemble a fairly powerful and high-performance machine, you should approach the choice of such an element with all responsibility.
The fact is that a poor-quality or inappropriate power supply will quickly disable various parts, for example, a video card, motherboard or processor, the repair or replacement of which will be quite expensive. In this regard, we decided to devote our today's review to the best power supplies of this year that are only on the market. However, before proceeding with the analysis of the characteristics and operational capabilities of a particular model, let's first look at the key points that you need to pay attention to when buying such a device.
Summary of the rating:
How to choose the right power supply for your computer?
First, let's take a closer look at what voltage is designed for which elements. 3.3 V is designed to power all cascades of system logic, including the motherboard itself and RAM. 5 V is used for PCI logic and IDE elements, and SATA devices also belong here. 12 V is the busiest line, as it is used to operate the video card and processor. The first two lines are in most cases not loaded too much, so you can not pay special attention to them when buying - even the minimum values will almost always be enough.
The load on the last line is very high, since the most demanding in terms of resources video card and processor are fed from it. Be sure to pay attention to the number of connectors in this device. Blocks of the latest generations are able to provide additional power to the video card, especially since they are released more and more powerful, respectively, the requirements for the amount of resources will be much higher.
The overall dimensions do not play a special role - they can be selected for the case, but sometimes they do the opposite: first choose a device, and depending on its size they buy a case. The most common is the ATX standard, however, there are more compact models on sale - SFX, TFX, CFX. They are suitable for users seeking to create a system that takes up a minimum of free space. Be sure to pay attention to the efficiency of the product. It is not very difficult to calculate the required power of the unit - you need to add up all the indicators of the elements and add 15% of the margin in case you plan to upgrade the computer in the future.
When compiling our rating of the best power supplies, we took into account the feedback of users and professionals, the ratio of price and quality of the model. In order to make it more convenient for you to read it, we decided to divide it into three groups - cheap, medium and expensive. We hope that after reading this review, you can easily select the necessary equipment for yourself.
Inexpensive price segment
3.GIGABYTE GZ-EBS50N-C3500W
This is a good enough choice for a home or office personal computer, which is planned to be used mainly when working with documentation. The main element is a DC-DC converter, which can provide all the elements with the necessary voltage. In addition, there is a special protection system inside that protects the device from a short circuit. This allows you to maintain the health of the elements in a personal computer. The rated power of this equipment is 500 watts - this is enough to connect a medium-power video card and a quad-core processor. In addition, under the case there are several more protection systems - from overload and from power surges, which can also have a very negative effect on the entire computer. The diameter of the fan is 120 mm - this ensures high-quality cooling of the elements and prevents overheating of the equipment. Overall dimensions are 15x8.5x14 cm - standard indicators that are suitable for most system units.
Connectors are enough to connect a large number of devices. For the motherboard, the type of connector is 2- + 4 pin, for the processor 4 + 4 pin, for the video card 6 + 2 pin. In addition, there are three 15 pin connectors for connecting various types of SATA devices (usually they are hard drives), there is one 4 pin Floppy connector, which is used to power the drive. The device is housed in a black-painted stainless steel metal case. The surface of the casing is perfectly smooth, which protects it from dust accumulation. The hole for all wires is equipped with a rubber ring that does not allow fraying of the braid. The cooler is closed by a thin wire grill, thanks to which there is a large access to fresh air, moreover, right through it you can get to the fan and clean it.
Benefits:

The leader of our rating of power supplies of the year is this model. It is characterized by a rather interesting appearance - the case is painted black, all connectors are neatly labeled and signed, the ventilation grill has an original shape - the holes are elongated, have a rectangular shape. It is worth noting that such holes are located not only on the cover itself, directly above the fan, but also on the walls, on either side of it. There is an opinion among users that they were made not so much to improve the cooling system, but to make the ring LED fan illumination more noticeable. At the bottom of the case is a sticker with the main parameters of this equipment.
Peak output power is significantly higher compared to that declared by the manufacturer - it is indicated that it is 650 watts, but if necessary, this parameter increases to 780 watts. This allows you to use this equipment to build powerful gaming computers. The device supports input voltage in the range of 100-240 watts. The case is made of fairly thick metal, has a black color. Here, a fan with a diameter of 140 mm and a rotation speed of 1,500 rpm are the main element of the cooling system. Part of its area is covered by a special screen, which allows to optimize the movement of air flows in the product itself.
Benefits:
- Very original appearance;
- Provides RGB LED backlight type;
- The increased number of connectors;
- Superior work efficiency
- There is a computer application that allows you to analyze all the processes occurring in the power supply.
