How to Check the Wattage of a Power Supply in Windows 10

​A power supply’s wattage rating tells you the maximum amount of power the PSU can deliver to your computer’s components. To find out how much wattage your power supply has, go to your computer’s BIOS.

The BIOS is a software that enables communication between the computer’s hardware and operating system. To enter the BIOS, you need to press a key during the boot process. The key varies depending on your computer’s manufacturer, but it’s usually F2, F10, or Del. 

Once you’re in the BIOS, look for a page that shows information about your system. This page is different for every BIOS, but you should be able to find the power supply’s wattage under a section called “Power.”

If you can’t find this information in the BIOS, you can also check the power supply itself. Usually, there’s a label on the PSU that lists its wattage.

As long as your power supply has a higher wattage than the recommended wattage for your graphics card, you should be fine. For example, if your graphics card needs a 400W power supply, a 500W PSU would be more than enough.

If you have multiple components that need power, add up the wattage of all those components to get your total power draw. Then, make sure your PSU has enough watts to handle that total.

It’s also important to note that your power supply will use more watts when it’s under load than it will when it’s idle. So, if you’re gaming or doing some other resource-intensive task, your PSU will use more watts than it would if you were just browsing the web or working in a word processor.

Make sure your PSU has enough headroom to handle your computer’s peak power draw. A good rule of thumb is to get a power supply that’s rated for at least 25-30% more watts than your computer will ever need. That way, you’ll have plenty of headroom for any future upgrades you might make.

If you want to err on the side of caution, there are some online wattage calculators that can help you estimate your computer’s power draw. Enter in all the components you have and how much power they draw, and the calculator will give you an estimate of the total watts your computer will use under load.

Once you have that number, add 25-30% to account for headroom, and then find a power supply with a wattage rating that meets or exceeds that number.

How to Ensure the Wattage Rating is Accurate

​As a general rule, it’s a good idea to have a PSU that’s rated for at least 50-60% more power than your system will ever need. A higher-wattage PSU can also deliver power more efficiently than a lower-wattage one, which is important if you want your system to be as energy-efficient as possible.

There are a few different ways to check the wattage rating of your PSU. The most accurate way is to look at the label on the side of the PSU itself. The label will usually have the max wattage rating clearly listed.

If you don’t have the label handy, you can also check the watts rating in the specs for your PSU on the manufacturer’s website.

Another way to check your PSU’s wattage is to use a power consumption monitoring tool like Power Consumption Manager. This tool will tell you how much power your system is currently using, which can be helpful in estimating your future power needs.

Keep in mind that the wattage rating is only part of the story when it comes to choosing a PSU. The quality of the PSU is also important, so be sure to do your research before making a purchase.

How to Find your PSU’s Wattage in the Device Manager

​It’s always a good idea to know how much wattage your power supply unit (PSU) is putting out. This is especially important if you’re building or upgrading a gaming PC, as you need to make sure your PSU can handle all of the components. If you’re not sure how to find this information in Windows 10, don’t worry—we’ll show you how.

First, open the Device Manager by right-clicking the Start button and selecting “Device Manager” from the pop-up menu.

Scroll down and expand the “Processors” section.

Double-click on your processor.

In the resulting window, go to the “Details” tab.

Under the “Property” drop-down menu, select “Wattage.”

You should now see the maximum wattage your processor is rated for in the “Value” field.

Keep in mind that this is the maximum wattage your processor can draw, not the amount of wattage your PSU is putting out. Your other components will also draw power, so you’ll need a PSU that can handle the combined wattage of all of your components.

If you want to be extra safe, add up the maximum wattage of all of your components and then add 20-30% to that number. That will give you a PSU that can handle everything without breaking a sweat.
