As a gaming enthusiast, you might have wondered how much electricity your gaming laptop uses. This article aims to provide a comprehensive answer to that question, considering various factors that affect power consumption and comparing gaming laptops to desktop PCs. We’ll also discuss how to reduce electricity usage and calculate the cost of gaming on your laptop.

Factors Influencing Electricity Consumption


The Central Processing Unit (CPU) and Graphics Processing Unit (GPU) are the primary components that determine the power consumption of a gaming laptop. High-performance CPUs and GPUs consume more electricity as they work harder to deliver smooth gameplay and high-quality graphics.

Power settings

The power settings on your laptop can significantly affect its electricity consumption. High-performance modes increase the power usage, while power-saving modes decrease it.

Screen brightness

The brightness of your laptop’s screen also impacts its electricity usage. Higher brightness settings require more power, while lower settings conserve energy.


The amount of Random Access Memory (RAM) in your laptop can also affect its power consumption. More RAM typically means more power usage, as it allows for faster data processing and multitasking.

Storage drives

Storage drives, such as hard disk drives (HDDs) and solid-state drives (SSDs), also contribute to your laptop’s overall power consumption. SSDs are generally more energy-efficient than HDDs.

Gaming Laptop vs. Desktop PC

Power consumption comparison

Gaming laptops generally consume less electricity than gaming desktop PCs due to their smaller size and power-efficient components. Desktop PCs often have more powerful CPUs and GPUs, which can result in higher power consumption.

Price and performance

Gaming laptops are usually more expensive than desktop PCs with similar specifications due to their portability and compact design. However, desktop PCs generally offer better performance and upgradability.

Energy efficiency

Gaming laptops are designed to be energy-efficient to prolong battery life. This makes them more environmentally friendly than desktop PCs, which often consume more electricity.

Environmental impact

The lower power consumption of gaming laptops reduces their environmental impact compared to desktop PCs, as they contribute less to greenhouse gas emissions and energy consumption.

Reducing Electricity Usage

Optimizing laptop settings

Adjust your laptop’s power settings and screen brightness to conserve electricity. Enable power-saving features and lower the brightness when you don’t need maximum performance.

Upgrading components

Upgrade to energy-efficient components, such as SSDs, to reduce your laptop’s power consumption. Also, consider investing in a more energy-efficient GPU if you’re looking to upgrade.

Energy-efficient peripherals

Choose energy-efficient peripherals, such as LED-backlit monitors and energy-saving keyboards and mice, to further reduce your overall electricity usage.

Limiting gaming time

Limiting the amount of time you spend gaming on your laptop can also help reduce electricity consumption. Set gaming sessions with breaks to ensure you’re not using too much power.

Calculating the Cost of Gaming

Estimating power consumption

To estimate your gaming laptop’s power consumption, find the laptop’s power rating (usually measured in watts) in the user manual or on the manufacturer’s website. Multiply this value by the number of hours you use the laptop daily to get the daily power consumption in watt-hours.

Running cost

To calculate the running cost, multiply the daily power consumption by the cost per kilowatt-hour (kWh) in your area. Divide the result by 1,000 to convert watt-hours to kilowatt-hours.

Annual cost

To estimate the annual cost of gaming on your laptop, multiply the daily running cost by 365 days.


The electricity usage of a gaming laptop depends on various factors, such as the CPU, GPU, power settings, and screen brightness. Gaming laptops generally consume less electricity than desktop PCs due to their energy-efficient design. You can reduce your laptop’s electricity usage by optimizing settings, upgrading components, and limiting gaming time. To calculate the cost of gaming, estimate your laptop’s power consumption, running cost, and annual cost based on its power rating and the electricity rates in your area.


How can I make my gaming laptop more energy-efficient?

Optimize your laptop’s power settings, lower screen brightness, upgrade to energy-efficient components, and use energy-saving peripherals.

Do gaming laptops use more electricity than regular laptops?

Yes, gaming laptops typically use more electricity than regular laptops due to their high-performance CPUs, GPUs, and other components.

Is it more cost-effective to game on a laptop or a desktop PC?

Gaming laptops generally consume less electricity than desktop PCs, making them more cost-effective in terms of power consumption. However, they are usually more expensive upfront.

How can I calculate the electricity cost of my gaming laptop?

Estimate your laptop’s power consumption based on its power rating, then calculate the running cost and annual cost using electricity rates in your area.

Do energy-efficient gaming laptops compromise on performance?

Energy-efficient gaming laptops may have slightly lower performance compared to their power-hungry counterparts, but they still provide a satisfactory gaming experience while consuming less electricity.
