When choosing components, users of a personal computer often do not pay due attention to the choice of a power supply. If the computer is office and has low performance, this may not matter much, and the power supply unit that comes with budget cases will be quite enough. But if the computer is gaming and has high performance, choose the power supply carefully and take into account several points.

Step 1
When choosing a power supply, be sure to calculate the total power consumption that the system unit will have. This value consists mainly of the power consumption of the processor, video card, hard drives and optical drive. You can find out these characteristics on the websites of the manufacturers of these components. Then multiply the resulting figure by 1, 5, the result will be the recommended power of the power supply.
Step 2
In addition to power, power supplies differ in the types and number of connectors for connecting devices. Check what connectors you need and if they are in the selected power supply.
Step 3
If possible, purchase a so-called "modular" power supply. It differs from conventional blocks in that cables with connectors are detachable, and you can use only those of them that are needed to connect devices. At the same time, unused cables will not clutter up the space inside the case. The only drawback of such blocks is their higher cost compared to conventional ones.
Step 4
When choosing, be sure to pay attention to how the power supply cools. It should be equipped with a large diameter fan (12-14cm), which should also be quite quiet.
Step 5
Buy power supplies from well-known manufacturers. Do not try to buy the cheapest unit of the required power. Good PSUs are never cheap, and trying to save money can have a detrimental effect on the quality and reliability of a PSU.
