How much Electricity does a Gaming Computer Use?

You might be aware that you have to set your laptops to sleep when you are not utilizing them. But it is all too easy to become satisfied and keep them on all day. Here the fact to consider is that how much electricity does a gaming computer use?

If you aren’t concerned with pricing, power consumption is essential when selecting components. However, increasing power consumption generates more heat and reduces the effectiveness of your cooling system. In this way, it puts more strain on your power source.

What is the significance of the electricity cost of gaming computers? 

Any power assessment must depend on your unique components. This is because every PC element consumes power, and everyone’s setup is suited to their specific demands. With all of the costs associated with a high-end gaming setup, few people consider the cost of power to have it functioning. 

So, I decided to discover out this! 

How much electricity does a gaming computer utilize? 

A typical desktop computer consumes between 60 and 300 watts of power. Thus, there are so many various hardware combinations. That’s why it’s challenging to determine precisely how much laptops use on aggregate.

It is not the best method to determine the energy usage by the computer power supply. It is because the power supply output is listed as the maximum number of watts a power supply can produce.

Following are some parts of a computer that consume more electricity! 

  • GPU 

The GPU was created for data programming and is utilized in various applications, including graphics and video rendering. GPUs are becoming more prominent for usage in creating opportunities and machine intelligence, despite their best-known use in gaming (AI).

  • Integrated GPU 
  • Discrete GPU 

As an outcome, it consumes a peak of 170 watts of power. There are also some unusual scenarios in which the GPU has two 8-pin ports. So, if you put all of the figures up, you will obtain a total of 375 watts, but it is an extreme scenario.

  • Video Card

A computer’s power generation is also highly influenced by its video card. It is because a high-end video card can consume a lot of power. For example, it can utilize as many powers as one card during higher gaming. Also, 3D rendering can consume a considerable amount of energy. 

It is estimated that a typical current desktop PC consumes around 100 watts of power without the LCD screen.

  • CPU 

When you use a computer to browse social media, send an email, or surf the internet, your CPU is hardly operating. When you play games on a computer, your CPU is running at full speed. 

Most intensive gaming PCs run in the full mode for about 4.5 hours each day. Commercial PCs, on the other hand, do not perform heavy computations. Therefore, they only use high-power modes around 1% of the time.

  • Power Supply Units 

A power supply is an electrical component that may provide electricity generation to an electricity gadget. For a computer system, a current supply voltage must deliver at least 18A on the +12V rail. Most mid-range gameplay PC designs may operate on 450-600W PSUs, based on the GPU.

  • Motherboard

Regular Motherboards consume 25 to 40W energy, and high-End Motherboards consume 45 to 80 W energy. The factors that affect motherboard power consumption are the number of power phases, type of voltage regulator, integrated chipsets, and modules.

  • RAM/ROM 

The result varies depending on several factors, such as the system component, installed apps, and the category of distinct memory. However, for every 8GB of DDR3 or DDR4 memory, you need to allow roughly 3 watts of electricity.

Does 3D performance require most electricity? 

Graphics cards’ power usage has skyrocketed in recent years. The highest versions consume between 110 and 270 watts from the energy source. Thus, an excellent graphics card consumes as much electricity as the rest of the application in a PC system. 

Do you want to update to a dual-chip card or expand your machine with an additional video card? The GPU is the most significant factor in deciding how much power your next power source can deliver

How to negotiate the electricity used by the gaming computer? 

Before starting, you need to consider few factors that can help you out. Following are the factors! 

  • Your PC’s Components 
  • How you use your computer 
  • Measuring your electricity usage 

PC’s Components 

It is also essential to consider that how much energy your gaming PC is consuming. A robust game Console with top-of-the-line specs will consume more energy. On the other side, a Chromebox with a reduced power CPU will use less energy while it is underuse.

How you use your system 

Only because your PC has a 750-watt power supply doesn’t guarantee it will require much electricity all of the time. Most PCs have power-saving capabilities that reduce your energy consumption. These functions help when the machine is inactive or performing simple tasks such as accessing the web.

Measuring your Electricity Usage 

The usage of the system varies so much from Computer to Computer and person to person. In this direction, the most straightforward approach to determine your electricity bill is to test it yourself. 


It is the most frequent question to ask that how much electricity does a gaming computer use. So, I have cleared all the points in this article to answer this question. By reading all the approaches, you can get this information. 

Also, Thermal Design Power (TDP) ratings are provided by producers for parts such as CPUs and graphics cards. It might help evaluate power usage, but they aren’t always correct.
