How to calculate the power supply?

Many gamers are collected every year or two yearsa new computer to enjoy modern powerful games. In order to assemble a new computer, it is necessary to understand its device, and also be able to calculate the power of the components. Due to this, you can always calculate the power of the power supply unit for the computer, which will power all these devices. But not everyone knows how to do this.

Let's take a closer look at how to calculate the power supply.

Self-calculation of power unit power

Calculating the power of the power supply for the configuration of your computer is not so difficult. For this you need to know:

• Type of disk drives and their number;
• Installed sound cards, TV tuners, wireless modules, keyboards, mice and other devices that are powered by a computer;
• Type of motherboard and name;
• Type and number of coolers in the computer;
• Is there a backlight and its power consumption?
• Number and type of hard drives;
• Number and type of RAM;
• The model of the video card and processor, as well as their power consumption.

Knowing all this information about the future computer, and alsopower consumption of all components and devices, you can summarize the data and get a certain number of watts of power consumption. Based on this information, it is necessary to select a power supply. However, it should be taken into account that power consumption can be even higher, so it's worth adding 20-30% to the value, which will give an extra amount of power, for example, for overclocking the processor and video card.

And always it is worth considering that different manufacturers of video cards, CPU, RAM, hard disk and motherboard power consumption are different and are set inaccurately.

If you are too lazy to climb through the documentation and learneach component for energy consumption, you can go to the site nimafirst.com.ua and calculate the power of the power supply automatically. However, remember that this calculation will be approximate.
