Manually it is hard to calculate the exact power usage, yet you can still find an average power consumption value or max power consumption value. I hope this article was able to explain to you ‘How Many Watts Does a Gaming Laptop Use?’ To understand the basics of power consumption of different electronic devices, you should check this excellent article on too. To know the exact cost of using your laptop for 6 hours, you can check this simple calculator. The device will record the power usage for the entire 6 hours and show you in KWh rating. So let’s say you connect your gaming laptop to a charger via the Kill A Watt device and you do gaming session for around 6 hours. However, the major USP of this device is that it tracks the KWh usage till the time a device is plugged into it. Once the battery is charged, the laptop will then draw power directly from the charger rather than the battery, and you can notice how much power your laptop draws in real time. Until the time the battery is charged, the Electricity Usage Monitor will display the value as 60W because the battery is being charged at that rate (with minor fluctuations). On a device like P3 Kill A Watt, you can check various factors like Volts, Ampere, Watts, Frequency and so on.īasically, if you’re using a regular laptop that is low on battery and you connect it to a 60W charger via Kill A Watt. If you’re unhappy by mathematically calculating electricity usage, then an Electricity Usage Monitor like P3’s Kill A Watt can exactly compute how much power your laptop is drawing from the wall socket.Ī device like this can be used to monitor the power consumption of any electrical device or appliance in your house.Īll you have to do is attach the Kill A Watt device to your wall socket and connect the laptop charger to the 3 pin socket in the device. Yet if you want to know the whole power consumption then jump onto our next method. However, to be true it’s tough to calculate the exact power consumption of each component in a laptop. Considering a 4K display, then the power consumption will be higher. While the laptop is in load, the power consumption of these two components increases by around 10-15%, whereas on idle it can be as low as 10-15W.Ĭonsidering the other components in the laptop like Screen, Keyboard, RAM, Wifi, HDD/SSD, the total power consumption can anywhere be between 135W-150W on load.Įven the Full HD screen’s power consumption varies from 0.5W on idle to 5-15W on full brightness. The TDP for CPU is 45W and for GPU is 75W, and when added results in 120W. If you check the official specifications of Intel and Nvidia, you’ll find the power consumption of both the components. The CPU and GPU in this laptop are Intel Core i7-8750H and Nvidia GTX 1050 Ti respectively. Let’s take an example of another popular gaming laptop, i.e. Manufacturers of all CPU and GPU list out the Max Power Consumption (TDP) in their specifications. In a gaming laptop, the two highest power consuming components are CPU and GPU. However, to solve this issue, there are two easier alternatives.ġ. It’s only after you’ve purchased the laptop, you can notice the Watts on the charger itself. Most manufacturers don’t show the actual power consumption of their gaming laptop or do not mention the rated Watts on the charger in the specifications page too. Hence at any given time the 13” MacBook Pro will not consume more than 61W of power and no more than 87W for the 15” version.įor a broad idea on idle the 13” MacBook Pro has an average power consumption of around 13W and while in sleep, the power consumption drops down below 1W.īut most of these power consumption values come from the battery however, when it comes to gaming laptops, the majority of them are connected to the charger during gaming sessions. The latest 13” version of MacBook Pro is supplied with a 61W USB-C Charger, whereas the 15” version is supplied with an 87W charger. How Many Watts Does a MacBook Pro Charger Use?Īs we all know, MacBook Pro is one of the most influential and powerful laptops. To make things straightforward, let’s jump onto a very known and popular laptop. Hence for any given time, your gaming laptop will not surpass its maximum rated power or for another instance it will never be higher than the capacity of the charger itself. Yet, the rated maximum power for Acer Predator Helios 300 is 135W. This indicates the max power consumption by the laptop will never exceed 180W per hour. For starters, to find the maximum wattage that your gaming laptop will consume, just check the wattage ratings on the charger.Ī favorite gaming laptop like Acer Predator Helios 300 comes with a 180Wh charger.
