How much amps does a gaming computer use?

How much amps does a gaming computer use is a difficult question to answer. If it was not so, you would not have come to the internet to search for this topic in the first place, right? Well, this question is made even harder to answer for the fact that everyone has a different pc with different configurations. 

Computers have become a necessity for almost everyone around the world. Many people earn their living through it by not only doing productive works such as editing but also gaming, as well. A gaming computer with top-of-the-line specifications will draw more power than a normal computer with normal specs. But there are a lot of things to know and consider before you can find out the amps gaming or any computer use. 

In this article, we will discuss the amps a gaming computer use. So, without further ado, let us begin. 

Previously we mentioned that you need to know a few things before you can calculate the amps consumed by a gaming computer. We will answer those questions first and then go into the rest of the details. 

What can be considered a gaming computer?

In the simplest of words, a gaming computer is one that you use for gaming. In reality, you can use any computer with a decent enough chipset to play games. So by this definition, almost every computer is a gaming one. Well, that is one way to look at it, but that does not tell the full story. You see, a gaming computer is one that you build, specifically keeping gaming in mind. 

The most common difference between a gaming computer and a normal one is the GPU or the graphics card. We know games need to render high-quality images to deliver a playable FPS or frame per second, and without a dedicated GPU, it is not quite possible to do so. The integrated graphics card of your CPU can render well enough for some light gaming but not for heavy gaming. The AMD Ryzen series APUs have changed this theory a bit over the years by delivering powerful integrated GPUs. But they are a far cry from a dedicated graphics card.

Another determinant of a gaming computer can be the monitor. For everyday users, monitors do not play a major role as they just use them to fulfill basic needs. But gamers require high refresh rate monitors that can view every scenario as smoothly as possible. If you look at the specs of any professional gamers, you will see a high refresh rate monitor for every single one.

How much amps does a gaming computer use?

There is a simple equation that you can use to find out how many amps does your gaming computer use. But to solve that equation, you will need to find out some necessary information beforehand. The equation is 




So, you can see that you have to know how many watts your computer draws and the voltage rating of your area. 

How many watts your computer draws

Just like we mentioned before, every computer has different specs, and for that reason, the power each system draw can be variable. To find out how much power your system draws, all you need to do is look at the number on your power supply. People mostly use a 500-watt power supply. But check yours to be confirmed about it. If you cannot see your PSU through your casing, you can check the PSU box or look it up online to find it out. 

But you have to know that you cannot accurately determine the total power your system draws. A system does not always draw the full power of the power supply unit. Usually, it draws less power than what the PSU shows. But the number on your PSU shows an approximate number that a system can draw. 

The voltage rating of your area   

The next thing that you have to know is the voltage rating of your area. The voltage rating can be different based on the country you live in. You can easily find it by looking up the internet. 

Calculating the amps of your Gaming computer

We are assuming that your pc draws 500 watts of power, and the voltage rating of your area is 220 volts. Now all you have to do is place the numbers on the equations and calculate them.




So, if we place te numbers, 


AMPS= = 2.27 amps.


Things to keep in mind

Usually, most pc builders buy a PSU higher than what the system needs. Doing so ensures that the system will not face any power-related issues while operating. So, your computer will mostly draw less power compared to what the calculations say. Another thing is that a computer does not always draw the same amount of power. It draws only the power it needs at a certain time. Doing light works will not draw as much power as doing heavy works. 

The calculation only shows how much power your computer draws. This equation does not count the additional power a monitor draws. A high-end monitor can draw a lot of power. Some users also prefer using multiple monitors. Others add a high-end sound system to their setup. These additions will increase the total number of amps. 


If you have read through all that, you should be able to understand that how much amps does a gaming computer use is not as easy to answer as it might seem. A computer is a complex machine with a lot of parts inside of it. Every part draws a different amount of power based on how you use your computer. The power count for a gaming computer is naturally higher because of the addition of a dedicated graphics unit. Gamers also prefer high-end monitors as well. So, finding out the exact power consumption of a gaming system is really difficult. But we can find a relatively close power consumption number using a simple equation.

We hope this article helped you.
