How to choose a power supply for a computer?

The main criteria for any power supply is power. In order to understand how much power is needed, you need to add up the total power required by all of your components, and then, to be safe, add a small margin (15-35%). This kind of power reserve will increase the overall stability of the system and, in the future, will allow for system upgrades. For simple tasks (surfing the Internet or using office software), a 300-500W power supply will be enough. For more complex work, such as gaming, it is recommended to use a power supply with no less than 500-850W. The required power for professional tasks (graphics design or audio/video editing) is 850-1000W or even more.

The second criteria: available connections. There are 2 types: Standard - the connection to the components is made with the help of built-in wires, which are included in the power supply. A more economical option than the alternative, but you need to pay attention to the connectors on your motherboard. For example, motherboards tend to use 24 or 20-pin sockets, while CPUs tend to use 8 or 4-pin sockets. Modular power supplies – Provide the option to only connect the wires you need to the power supply. This type of power supplies are more expensive, but much more convenient to use, because you don't have to think about where to hide the excess wires in the case. These power supplies are universal because they come equipped with a "20+4 pin" motherboard connector that fits both of the above-mentioned variants. They are also equipped with universal connectors for the CPU - "4+4". Using these kinds of power supplies, it is possible to connect all kinds of components without worrying about compatibility.

It is also important to pay attention to cooling - the power supply fans protect it from critical overheating. Possible fan sizes: 80mm – Low efficiency and loud operation. Quite outdated, but they can still be found on weak desktop computers. 120mm – A good option for a mid-range computer. 130-140mm – Perfect for powerful computers used for gaming, graphics design and other complex tasks. Efficiency - an important indicator that determines the power supplies efficiency. It is measured as a percentage. The closer to 100%, the more efficient the power supply is. To make your choice easier, the Energy star 4.0 standard was invented. According to this standard, the efficiency of any power supply must be at least 80%. All blocks that meet this standard (marked with the 80 Plus label) are divided into the following categories: Bronze – from 82% to 84% Silver – from 85% to 87% Gold – from 87% to 90% Platinum – more than 90% It is recommended to choose a power supply with the “80 Plus” label, as they are not that more expensive and will last much longer than their alternatives without this standard.

Of course, you should also pay attention to the form factor - there are four possible types: TFX - Most often found in office computers, 85x65x175 (Width, height, depth in millimeters) ATX – The most popular option, 150x86x140mm SFX - Similar to ATX, only slightly smaller, 125x63.5x100mm EPS – Used for the most demanding systems. An improved ATX version with greater depth up to 240mm and eight connector sockets.
