PCs are incredibly versatile devices. They have become a crucial part of our lives, whether we use them for work, play, or other activities. They can quickly take on very challenging tasks. But how much energy do computers actually consume to perform these tasks? This article will answer just that.
Read on to learn different methods to check how much power your PC is using. We will cover two main techniques that will allow you to discover this using hardware and software.
How to Check How Much Power Your Hardware PC is Using
Checking your PC’s power consumption using a wattmeter is arguably the best way to go. These dedicated electricity usage monitors are perfect if you plan to check your PC and laptop power usage frequently.
Its estimated margin of error is about 0.5%, giving you the most accurate result you can get. Additionally, energy consumption meters are quite easy to use. You just need to connect your PC or laptop to the meter and plug it into a wall outlet. The measurement takes a few seconds and you will see the energy consumption in kilowatt-hours (KWh).
Some of the top-rated units on the internet include kuman and pony.
If you have never used similar devices before, you may have trouble analyzing the results. But you can always compare your PC’s power consumption with average usage figures to get a good idea of how much or little power your device is using.
Gaming computers require up to 500 watts per hour to operate efficiently, while non-intensive use (surfing the Internet, word processing, etc.) requires up to three times less power. However, the figures vary depending on the software and hardware installed on the PC, as well as its location.
If you use a PC for heavy crypto mining, which requires computers to run 24 hours a day, it is obvious that your electricity bill will skyrocket. Energy efficient equipment can greatly reduce energy consumption. For example, a 10TB hard drive consumes four times as many watts as its SSD counterpart. Additionally, the higher the RAM and number of cores, the less power a computer will use. As you can see, many factors influence here.
How to check how much power your PC is using with a Windows app
The easiest way to calculate how much power your PC consumes is through software. Online tools perform energy consumption analysis quickly and are easy to use. However, there is a drawback. They are a less reliable option compared to hardware calculators. They only perform the analysis for a short period of time and may not accurately represent actual energy consumption.
You can use online tools like the OuterVision calculator to measure Windows power consumption. This analysis is free and provides data on charging power, estimated costs, and recommended power supply (PSU). There’s also an “Expert” mode for those versed in PC specs.
Here’s how to use OuterVision:
- Visit the Exterior view website.
- Click on Essential for standard calculations or Expert for the advanced.
- Enter the information for each p in their respective boxes.
- Click Calculate to get results.
Once the analysis is done, the site offers recommendations on the best power supply options for different categories. You can compare recommended power supplies, adjust the cost to see annual energy cost information, and choose the power supply that suits your needs.
Another application that you can use on your Windows PC is LocalCooling. This free program shows how much power your computer uses, with specific data about the hard drive, monitor, and other items. You can set it to turn off your monitor, slow down disks, or even put your computer into sleep mode.
To get the most out of this application, it is best to use it for a few days and during different activities. A good thing for environmentalists is that it shows them how many trees and gallons of energy it saved. You can take your ecological fight to the next level and compete against other users!
However, the main disadvantage is that you cannot change the units of measurement.
Here’s how to use Local cooling:
- Download the application from their website.
- Run the application on your PC.
- Navigate to Settings and click My power tab.
- You’ll see a rough estimate of how much power your PC uses.
How to Check How Much Power Your PC is Using with a Mac App
Knowing how much power your Mac uses can be useful for many reasons. You can know which part of your system uses the most energy and whether you can reduce overall consumption.
Mac allows you to view your power consumption in Activity Monitor. You can use the Energy dashboard to analyze overall power usage and get more details on how much power each app uses.
Here’s how to check your power consumption in Activity Monitor:
- Launch the Activity Monitor app on your Mac. Just type Activity monitor in your search bar and click on the app from the results.
- Click on the Energy button.
- Select Viewso columns to show more columns. Select the ones you want on the screen.
You’ll be able to see the power usage of every app and process on your Mac at the top of the window.
Here is some basic information to look for:
- Energy Impact. This is a relative measure of an application’s current power consumption. The lower the energy impact number, the better.
- 12 hour power. The energy impact of an app over the last 12 hours or since the device was started. Please note that this column is only available for Mac laptops.
- Graphic card. This shows you if the application requires a high-performance graphics card. This information is only available for Macs with more than one graphics card.
There are some third-party apps you can use to calculate how much power your Mac uses.
One of the most efficient and information-filled programs to check your energy consumption is OuterVision. This free app gives you information about your estimated electricity costs related to your Mac’s power usage, charging power, and more.
Simply follow the steps below to run the OuterVision test on your Mac:
- Go to the Exterior view website.
- Select Essential for standard calculation or Expert for advanced.
- Enter information for each p.
- Click on the blue Calculate button to see the results.
The software will provide you with advice on the best power supply options for your Mac. It will also allow you to modify costs to see annual power consumption expenses and more.
Stay on track with your PC’s power consumption
The amount of power each PC unit consumes is very inpidual. Many factors influence power, including software, hardware, location, etc. The most accurate way to calculate energy usage is to use a hardware device, such as an energy consumption calculator that plugs into an outlet. A little less accurate but just as valuable are online tools like OuterVision, LocalCooling, or your own Mac’s Activity Monitor.
Whichever method you choose, you’ll get a decent estimate of your PC’s power consumption. Just be sure to check your power consumption several times a day and during different activities. If you have any questions related to the topic, please drop us a comment below.
