How to Measure Your PC’s Power Consumption: Easy and Accurate Methods


Do you want to keep tabs on your PC’s power usage? Whether you’re trying to reduce power consumption, monitor it during demanding tasks, or simply satisfy your curiosity, measuring your computer’s power draw is essential. Luckily, there are various ways to accomplish this accurately. From software solutions to hardware options, we’ve got you covered. So let’s dive into how you can easily measure your PC’s power consumption in a few simple steps.

Use an Online Calculator for a Rough Estimate

If you’re looking for a general idea of your system’s power usage, an online calculator can save you the trouble of taking measurements. Here’s how you can make a quick estimate:

  1. Head to the OuterVision website and open its Power Supply Calculator page.
  2. Depending on your level of expertise and knowledge about your computer, select the Expert or Basic tab.
  3. Input as much information as possible, including components, coolers, overclocking details, and any other relevant data.
  4. When ready, hit Calculate to get a rough idea of your PC’s daily power consumption.

Obtain Detailed Measurements with HWInfo

If you want more specific and detailed information about your PC’s power usage, HWInfo is an excellent tool that can provide comprehensive insights. Although it requires a little calculation, the results are worth it. Follow these steps to use HWInfo effectively:

  1. Visit the HWInfo official site and download the application. Install it following the on-screen instructions.
  2. Run the app and select Sensors only when prompted.
  3. HWInfo presents a wealth of information, so it may seem overwhelming initially. However, the data you need is right there; you just need to find it.
  4. Scroll down until you locate the CPU section. Look for the CPU Package Power, which represents the total power consumed by your CPU at that moment.
  5. Find the section for your graphics card and search for either Total Graphics Power or Total Board Power.
  6. Add the CPU Package Power and the graphics card power together to get an estimate of your system’s power usage. If your motherboard and memory support power sensors, consider adding that data for increased accuracy.
  7. For a more precise measurement, put your PC under a load (e.g., gaming or other resource-intensive tasks) and retake the readings to determine the power usage during such activities.

Measure Power Consumption with Hardware

Eager to obtain the most accurate readings for your PC’s overall power usage? To achieve this, you’ll need to measure the power supply’s connection to a wall outlet using an external power meter, like the P3 Kill A Watt Electricity Monitor. This device allows you to take precise measurements of your PC’s power consumption and is available from various retailers for around $20 to $40.

Simply plug the power meter into the wall outlet, then plug your PC’s power cable into the meter. Next, turn on your PC, and the Kill A Watt meter will display the power usage.

Knowing how to check your PC’s power consumption can help you make informed decisions about future upgrades. Although top-of-the-line graphics cards may enhance your gaming experience, it’s important to consider their power-intensive nature.

Now, armed with these easy and accurate methods, you can measure your PC’s power consumption with confidence and improve your power management strategies.
