It is worth taking a power supply for a PC, taking into account the following characteristics:
- Power;
- efficiency;
- Size;
- Cooling system.
The main parameter for PC power supplies is power. In this case, the principle is relatively simple, the more productive the hardware on the computer, the higher its power consumption, which means that a more powerful PSU will be required.
A standard PC will need a power supply up to 400W. The gaming machine will require 500-700 50 watts. A computer for 3D modeling, working with video and graphics needs to be connected to a power supply unit with a power of up to 1500 W.
However, power is not the only important indicator. Another important characteristic is efficiency. The higher it is, the lower the level of losses when converting AC to DC. For standard models, the efficiency is approximately 70%. However, modern developments and applications of innovative technologies allow large brands to approach 100%.
PSU models that have passed extensive efficiency testing can be assigned an 80 plus certificate. Depending on the results obtained, the class can be from “Bronze” to “Platinum” and “Titaniun”. For such power supplies, the efficiency ranges from 80% to 96%.
Power supplies are available in three sizes:
- shortened;
- Standard;
- Extended (such models are characterized by increased power from 1000 W).
In most cases, it is recommended to purchase a PSU of a standard size.
During operation, the power supply generates heat, so that it dissipates, a cooling system is needed. Usually it is represented by a built-in fan. For cooling, a fan with a standard diameter of 120 mm is used. The cooler makes noise during operation. Silent devices are equipped with a passive cooling system. The disadvantage of such devices is high speed, in addition, their power is very limited.
Fans of neat assembly should pay attention to power supplies with cable management. It is a modular panel that allows you to neatly connect the necessary components. At the same time, the cords are fixed with cable ties and removed into special channels.

The calculation of the required power of the power supply is determined depending on the characteristics of the two main consumers: the processor and the video card. During operation, they convert the consumed energy into heat. TDP (or Thermal design power) is an important design requirement for heat dissipation. To calculate the power of the PSU, add the TDP level of the processor and video card, after which the resulting number is multiplied by two. Let's take an example. For the Intel Core i5 10600 processor, this figure is at the level of 65 W, for the RTX 2070 video adapter it is 175 W. A 480 W power supply can ensure their operation. However, experts recommend leaving a margin of about 100 watts for the possibility of an upgrade. As a result, for this configuration, a 550-600 W model is recommended, preferably with 80 + Bronze certification.

When choosing a computer power supply, you should pay attention to the quality of the 12 V circuit. However, do not forget about 5 and 3.3 V circuits. The stability and durability of equipment depend on their work. The choice of power depends on the consumption of the components used.Choosing a model with a large margin is not recommended, as this will not affect performance in any way. Cable management with detachable cords will allow you to clean up the inside of the case, improve cooling efficiency.
