how many watts does a gaming laptop consume

If you have a gaming laptop maybe sometimes you worry about how many watts does a gaming laptop use? 

Well, I also have this question in my mind so our team did research about that and find out some of the major facts that everybody should know.

Maybe you also have further questions in your mind that Does gaming laptop consume more than a normal PC or equivalent to a gaming pc? Well, we answer all those related questions in this article so stay tuned with us. 

how many watts does a gaming laptop use

Key Factors of gaming laptop Power consumption

First thing first you should know what are the key factors that your gaming laptop consuming power.

These factors are very important and play a very important role in your laptop to decide how much your gaming laptop is consuming power.

CPU : (Central Processing Unit)

CPU is one of the main factors in gaming laptop power consumption because gaming laptop CPU tends to be heavier and faster in performance to load heavy things quicker.

As its heavy for high performance so it consumes more power than a normal laptop CPU.

Normally Core i5 and i7 chipset use in a gaming laptop.

No one else talked about the generations of the CPU but it also matters in power consumption, the latest generation is more power-efficient in front of old ones.

The higher the CPU generation is the more efficient in power, in high generations we have 7th (Kaby Lake), 8th (Kaby Lake R), 9th (Coffee Lake), and 10th (Cannon Lake/Ice Lake).

Intel Low-End CPU (Core i3)55-73 W
Intel Mid End CPU (Core i5)73-95 W
Intel High-End CPU (Core i7)77-95 W
Intel Top End CPU (Core i7-E)130-150 W
AMD Low-End CPU (2 cores)65-95 W
AMD Mid End CPU (4 cores)65-125 W
AMD High-End CPU (8 cores)95-125 W

GPU : (Graphical processing Unit)

Graphics card in your laptop is also one of the main factors of gaming laptop power consumption.

As we are talking about gaming laptops so gaming laptops having heavy GPUs to handle all those heavy games.

Heavy GPU’s tend to use more energy because it requires more power to perform well.                                     

Load Power DrawIdle Power Draw
Low-End Graphics Card (Under $125)25-86 W5-10 W
Mid End Graphics Card ($125 to $250)110-164 W8-13 W
High-End Graphics Card ($251 to $400)162-258 W12-20 W
Top End Graphics Card (Above $400)240-350 W39-53 W

Storage Device : (HDD or SSD)

The storage device is a necessary part of a laptop or computer because it Loaded all your software components in your machine.

As it is a working component so it consumes a little amount of electricity.

The difference between the power consumption of Hard Disk Drive and Solid State Drive is very negligible in terms of usage as you can see.

Solid State Drive SSD0.6 to 2.8 W
2.5″ Hard Disk Drive HDD0.7 to 3 W
3.5″ Hard Disk Drive HDD6.5 to 9 W


Factors that affect motherboard power consumption is Integrated chipsets and modules, For Example ( USB connectors, Add-on SATA connectors, WIFI chip, etc).

Regular Motherboard25 to 40 W
High-End Motherboard45 to 80 W

RAM : (Random Access Memory)

RAM module also adds some little to gaming laptop power consumption, the higher clock speed also leads to high voltage consumption.

The interesting fact is the 4GB DDR3 Ram stick consumes power as same as a stick of 8GB DDR3 Ram.

DDR1 RAM (2.5 Volts)4 to 5.5 W
DDR2 RAM (1.8 Volts)3 to 4.5 W
DDR3 RAM (1.5 Volts)2 to 3 W

Screen Size : (13”,15”, or 17”, etc)

Screen size is also one of the main factors in gaming laptop power consumption, normally gaming laptops have 15”-17” of screen size.

The larger the screen size is, the more energy screen consumes.

Well, the Brightness of the screen and the total Nits in the screen is also matters in the energy consumption of a gaming laptop.

In short; big screen sized laptops consume more power than that small and medium screens.

Screen Resolution : (HD+, 2K, or 4K, etc) 

Screen resolution is one of the main biggest factors of gaming laptop power consumption that a lot of people don’t give attention to.

Normally the gaming laptops come with the 1080p HD, 2K, 4K display and some of them are highly incredible with 8k display.

The fact behind the power consumption due to screen resolution is the pixel on the screen, The more pixels you have in your gaming laptop the more energy it consumes Because every pixel of your screen consumes some of a little energy. 

An HD+ screen has 1.4 Million pixels.

Backlight Keyboard :

A backlight keyboard also a factor of gaming laptop power consumption in a gaming laptop because normally a gaming laptop has RGB color lights in the backlight keyboard.

Normal backlight Keyboard1-2W
RGB backlight Keyboard2-3W

External Devices connected :

External devices connected to a laptop obviously contain some of the extra energy, and in gaming laptops normally people connect gaming mouse and gaming keyboard in external and that also the factor of power consumption in a gaming laptop.


How Many Watts does a gaming Laptop Use? Answer to this question is, gaming laptop uses more power than a normal laptop. Gaming laptops use 135 – 180W per hour it depends also on the gaming laptop model and CPU, GPU it uses.

The Gaming Laptop Vs. Gaming PC Power Consumption

The normal laptop can draw 60-watt energy whereas the common Desktop is 160-180W but the gaming laptop Consumes 135-180 watts and the gaming Desktop ranges from 400-1350W depending on the GPU. Generally, laptops are power efficient and tend to consume 80% less electricity than a Desktop.

And there is much difference a High-End gaming laptop consumes 135-180W and a High-End Gaming PC consumes 300W-700W.

What if you don’t provide the required power to the laptop?

In this case, if the power of the charger is too low so it’s just won’t work but if it is too high so it can cause a problem and It can also burn things in the laptop out.
