How to Check How Much Power Your Windows PC or Mac Is Using

Personal computers are very versatile devices. They have become a vital part of our lives, whether we use them for work, gaming, or other activities. They can quickly take on extremely challenging tasks. But how much power does the computer actually use to perform these tasks? This article will answer that.

How to Check How Much Power Your Windows PC or Mac Is Using

Read on to learn about the different ways to check your PC’s power usage. We’ll cover two main techniques that will enable you to find this out both in hardware and software.

How to Check How Much Power Your PC Is Using Hardware

Using a wattmeter to check your PC’s power consumption is arguably the best way. These dedicated power usage monitors are perfect if you plan to check your PC’s and laptop’s power usage frequently.

Their estimates have a margin of error of about 0.5%, providing the most accurate results you can get. Also, the power consumption meter is very easy to use. You simply connect your PC or laptop to the meter and plug the meter into a wall outlet. The measurement takes a few seconds and you will see the energy consumption in kilowatt-hours (KWh).

Some of the internet’s highest rated units include Kuman and Poniie.

If you have never used a similar device before, it may be difficult to analyze the results. But you can always compare your PC’s power consumption to average usage figures to get an idea of ​​how much power your device is consuming.

Gaming PCs require up to 500 watts per hour to run efficiently, while non-heavy use (browsing the internet, word processing, etc.) requires up to three times less power. However, these numbers vary depending on the software and hardware installed on your PC and your location.

If you use your PC for heavy crypto mining, which requires the computer to run 24 hours a day, your electricity bills will obviously skyrocket. Energy-saving gears can greatly reduce power consumption. For example, a 10TB HDD consumes four times more watts than a corresponding SSD. Also, the greater the amount of RAM and cores, the less power your computer uses. As you can see, many factors come into play here.

How to Check How Much Battery Your PC Is Using Using a Windows App

The easiest way to figure out how much power your PC is using is through software. Online tools perform power analysis quickly and are easy to use. However, there is a downside. They are a less reliable option than hardware calculators. They are only analyzed for a short time and may not accurately represent actual power consumption.

You can measure your Windows power consumption with online tools like the OuterVision Calculator. This analysis is free and provides data on load power, estimated cost, and recommended power supply (PSU). For those versed in PC specs, there’s also an “expert” mode.

Here’s how to use OuterVision:

  1. Visit the External Vision website.

  3. Enter the information for each section into its own box.
  4. Click Calculate to get the result.

Once the analysis is complete, the site provides recommendations for the best power options for different categories. You can compare recommended power supplies, adjust costs to view annual energy cost information, and choose the right power supply for your needs.

Another application you can use on your Windows PC is LocalCooling. This freeware shows how much power your computer is using, as well as specific data about hard drives, monitors, and other elements. You can configure it to turn off the display, spin down the disk, or even put the computer to sleep.

To get the most out of this app, it’s best to use it for several days in different activities. One great thing for environmentalists is that it can show you how many trees and how many fuel gallons of energy you’re saving. You can take your eco battles to the next level and compete with other users!

How to Check How Much Battery Your PC Is Using Using Mac Apps

Knowing how much power your Mac is using comes in handy for a number of reasons. You can see which part of the system consumes the most power and whether you can reduce overall power consumption.

Mac lets you see your energy consumption in Activity Monitor. You can use the Energy pane to analyze overall power usage and get more details about how much power each application is using.

Here’s how to check energy consumption in Activity Monitor:

  1. Launch the Activity Monitor app on your Mac. Just type “Activity Monitor” into the search bar and click on the app from the results.
    1 8
  2. Click the “Energy” button.
    2 3
  3. Choose View, then choose Columns to display more columns. Select the ones you want from the display.

You’ll be able to see the energy usage of each application and process on your Mac in the upper part of the window.

Here’s some basic information to look for:

  • energy impact. This is a relative measure of the application’s current power consumption. The lower the energy impact value, the better.
  • 12 hours power. The application’s energy impact over the last 12 hours or since the device was started. Note that this column only applies to Mac laptops.
  • graphics card. This will show you whether the application requires a high-performance graphics card. This information applies only to Macs with multiple graphics cards.

You can use some third-party applications to calculate how much power your Mac is using.

OuterVision is one of the most informative and effective software for checking your power consumption. This free app gives you estimated electricity bill information related to your Mac’s power usage, load wattage, and more.

Just follow these steps to run the OuterVision test on your Mac:

  1. Go to the external vision website.

The software will give you tips on the best power options for your Mac. It also lets you adjust costs to see your annual energy consumption bill and more.

Track PC Power Consumption

The power consumed by each PC unit is highly independent. Many factors affect wattage, including software, hardware, location, and more. The most accurate way to calculate your electricity usage is with a hardware device, such as a power calculator that plugs into an electrical outlet. Online tools like OuterVision, LocalCooling, or your own Mac’s Activity Monitor are less accurate, but equally valuable.

Whichever method you choose, you’ll get a reasonable estimate of your PC’s power consumption. Just make sure to check your power consumption several times a day during different activities. If you have any questions on this topic, please drop us a line below.
