Power Consumption Of Gaming Laptops

Power Consumption Of Gaming Laptops

Although laptops are portable, consume less power than giant desktops, but laptops that are specifically made for gaming (gaming laptops) also consume way more power than normal ones.

As gaming laptops do come with powerful GPUs and power-hungry parts, their TDP, as well as power consumption, is also pretty high. So, let’s discuss things you should know about the power consumption of gaming laptops in this post.

How much electricity does a gaming laptop use? Although normal laptops that are not specifically made for gaming, they can be run on 65W to 95W, gaming laptops typically consume from 130W to 200W and more depending on how much system resource the laptop is using. Also, the power consumption of gaming laptops increases by around 20% when you use them while plugged in.

That’s why, people often think that gaming laptops use a huge amount of power, but is it really true, are you getting good performance compared to power consumption? Let’s have a look:

Does Gaming Laptops Consume A Lot Of Electricity?

Gaming laptop still consumes a lot less power than desktops. If a user not overclocking a gaming laptop, the power consumption is more likely to stay below 100W (80W). On a desktop with a graphics card like 3070, you at least need a power supply (PSU) of 650W-700W.

Here are some of the best gaming laptops and their maximum power consumption. Note that, the power consumption I have given in the chart is almost maximum when not overclocked, but laptops can also exceed this in extreme overclocking scenarios.

LaptopsPower Consumption (Highest)
Asus rog Zephyrus G14150W
Alienware M15 R4140 W
Gigabyte Aorus 17G125 W

The power consumption depends on what task you are doing and how much system resources it is using.
As gaming needs a powerful graphics card, more RAM, and also a good CPU, so all these together fuels the overall power consumption.

Also, according to a test, gaming laptops consume 20% more power on average when they are directly plugged in while running than running in battery power.

Although I don’t recommend running laptops on battery power while gaming, but doing this can save money. You can read why I don’t recommend it from here: Do Laptops Run Better When Plugged In?

Basically, as it is almost impossible to fulfill the power requirements of gaming laptop’s high-end parts from the battery, so power-hungry parts like GPU, CPU restrict the performance and consume less power while they are getting it from the battery.

But when gaming laptops are used directly while plugged in then there is no worry, all the parts can consume power without any restrictions and that’s why the performance also increases when laptops are used directly while plugged in.

So, we have discussed the power consumption of gaming laptops till now but how much difference we get between a gaming laptop and a desktop:

Power Consumption Of Gaming Laptop vs Gaming Desktop:

If you are also thinking about do desktop computers really use more power than laptops, then yes, gaming laptops consume less power than desktops. This mainly happens because desktops have bigger and better parts that can give better performance than laptops.

This is obvious, as desktop mostly has separate parts for everything, all these parts combining consume more power than laptops where all the parts are placed together.

Bigger Parts:

Desktop parts are usually bigger and also more powerful than laptop ones. That’s why for high performance their power consumption is also too high.

While in laptops, the power-hungry parts like Graphics card, Processor are made specifically for it so that they can also run on low power. However, this lowers the performance of those parts, but it is important in the case of laptops as people also use them on battery power.

Separate Parts:

Desktops have separate keyboards, mice, CPU cabinets, monitors, and because of this general power consumption of desktops is very high. Also, nowadays people like RGB in their system, this is another factor for it.

Overclocking Capabilities:

We can take the performance of a PC to the next level by overclocking. It is also possible to overclock in laptops but as laptops cooling is not great, there is not enough space for airflow, so it is almost impossible to overclock at that level.

But the thing is when a PC is overclocked it consumes much higher power for giving only a little bit of performance. As overclocking is mostly done is desktops because of better cooling, that’s why the power consumption is also high on desktops.

Now, let’s understand in detail, exactly how much power difference we can see between a gaming desktop and a laptop.

For this, I am taking the example of MSI GE75 Raider laptop. It is a popular gaming laptop and consumes 45W power in normal conditions. But at extreme uses, this can be increased to 70-80W, but 45W is average.

Taking about the specifications of MSI GE75 Raider, it comes with RTX 2080 super GPU. Now, the desktop version RTX 2080 super has a TDP of 250W and you need at least a 650W power supply in your desktop if you have RTX 2080 super on your desktop.

But as we can see the same GPU consumes less power on laptops, it also gives less performance on laptops. The mobile GPUs ( made for laptops) are too small compared to desktop versions and that’s why give less performance too.

Laptop GPU Power Consumption:

GPU or graphics card is the most power-consuming part of the laptop and it also impacts the most in games. But the power consumption in laptop GPUs is way less than their desktop variants. Still, it needs 40W to 100W and more in laptops according to uses.

That’s why a normal laptop that is not made for gaming doesn’t come with high-end GPUs to reduce the power consumption and making them slimmer.
