How Many Watts Does Your Motherboard Use? 

Here is a thing for the computer geeks who ace computing skills but find it difficult to manage when it comes to the power consumption of the system. well, it is really difficult to handle if you lack information on the reasons for the high power consumption of your computer. Having said that, building a PC for the first time can be super intimidating. Pick the motherboard that matches the CPU. Pick the right RAM for the board. Choose how awesome the LEDs should look. Figure out how much all that will need power-wise!

How many watts does your motherboard use

When it comes to optimizing your PC build, understanding how many watts does your motherboard use is essential. On average, a motherboard consumes around 30 to 80 watts per hour. Of course, this number can vary depending on the type of motherboard you’re using. Gaming motherboards tend to draw more power due to their high-performance features. Additionally, the power consumption of your motherboard will be influenced by its current status. When overclocking components, the motherboard will naturally demand more power than when your machine is idling peacefully.

How to Check How Much Power your Motherboard is Using

Now that we know the ballpark figure for motherboard power consumption, how can you accurately determine the exact amount of power your motherboard is using?

How to Check How Much Power your Motherboard is Using

There are two main methods you can employ: referring to the manufacturer’s website and performing manual calculations, or utilizing software solutions that monitor power consumption in real-time.

Refer to the manufacturer’s website and perform some manual calculations.

Let’s start with the software solution. Some manufacturers offer 1st party software that provides information on power usage. For example, Corsair has a series of Corsair Link-enabled PSUs that allow you to keep an eye on the PSU’s temperature, fan speed, and voltage.

Refer to the manufacturer’s website and perform some manual calculations.

Additionally, there are freeware and open-source software options such as HWMonitor and Open Hardware Monitor, which attempt to provide comprehensive power usage information for all your components. However, keep in mind that these software solutions might not be universally compatible with every chipset.

Use a software solution that watches power consumption live.

If you find the software solutions unreliable or incompatible, you can turn to good old-fashioned research. Visit the manufacturer’s website and look for the expected power usage specifications for your CPU, RAM, and GPU when idle. Disconnect any USB devices, Bluetooth devices, and the internet from your machine to eliminate additional power draw.

Use a software solution that watches power consumption live

Next, use a physical energy monitor that plugs into a wall socket and acts as a passthrough for your PC’s power cable. Track the power usage over an hour, subtracting the power consumption of components you’re certain about but excluding the motherboard. The remaining value should give you an estimate of your motherboard’s idle power usage. While this method may seem a bit crude, it tends to be more reliable than software solutions.

Installed Components:

The power consumption of your motherboard is directly influenced by the components you have installed. From the CPU and GPU to RAM modules and storage devices, each component requires power to operate efficiently.

Installed Components

As you add more high-performance components to your system, such as powerful graphics cards or multiple storage drives, the motherboard needs to provide adequate power to support their functioning. The more power-hungry components you have, the higher the overall power demand on your motherboard.

Peripheral Devices:

Your motherboard serves as a hub for connecting various peripheral devices, including USB devices, external storage drives, and networking devices. Each device draws power from the motherboard to operate effectively. If you have numerous USB devices connected simultaneously, such as gaming peripherals, external hard drives, or other accessories, they collectively contribute to the power consumption of the motherboard. It’s a good practice to unplug any unused devices to reduce unnecessary power draw.

Wireless Connectivity:

Many motherboards offer built-in wireless connectivity options, such as Bluetooth and Wi-Fi. These wireless features enhance the versatility and convenience of your PC.

Wireless Connectivity

However, enabling these wireless functions consumes additional power from your motherboard. If you’re not actively using Bluetooth or Wi-Fi, consider disabling them to conserve power.

CPU and GPU Intensive Tasks:

The motherboard plays a crucial role in supporting the CPU and GPU, which are often the most power-hungry components in a PC. When you engage in demanding tasks like gaming, video editing, or 3D rendering, the CPU and GPU work at full throttle, resulting in increased power consumption. Consequently, the motherboard must supply additional power to meet the heightened demands of these components.


Overclocking, the process of increasing the operating frequency of your CPU or GPU beyond their default settings, can significantly impact power consumption. When you overclock, you essentially push these components to work harder and faster, which requires more power. As a result, the motherboard must deliver additional power to maintain stability during overclocking.


To mitigate excessive power demands and optimize your motherboard’s power usage, there are a few steps you can take:

Limit overclocking: 

While overclocking can boost performance, it significantly increases power consumption. Consider finding a balance between performance gains and power efficiency.

Manage peripheral devices: 

Manage peripheral devices

Disconnect any unused USB devices or peripherals that are not essential to your current task. This reduces the power load on your motherboard.

Disable unnecessary wireless features: 

If you’re not actively using Bluetooth or Wi-Fi, disable these wireless functions to conserve power.

Optimize CPU and GPU usage: 

Be mindful of resource-intensive tasks and consider optimizing them to minimize power consumption. For example, adjusting in-game graphics settings or using efficient software settings can help reduce the power demands on your motherboard.

Optimize CPU and GPU usage

By implementing these measures, you can strike a balance between performance and power efficiency, ensuring that your motherboard operates optimally without driving you or your PC mad.

Frequently Asked Questions

Can I use a power supply with lower wattage than the estimated power consumption of my components?

It is not recommended to use a power supply with lower wattage than what is required by your components. It may lead to unstable system performance, crashes, or even damage to your hardware. It’s best to choose a power supply that comfortably covers the estimated power consumption of all your components.

What is the significance of the 80 Plus rating for a power supply?

The 80 Plus rating indicates the efficiency of a power supply in converting AC power from the outlet to DC power for your components. A higher 80 Plus rating (such as Gold, Platinum, or Titanium) means better efficiency and less wasted energy, resulting in reduced heat generation and potentially quieter operation.

Can I mix and match motherboards and power supplies from different manufacturers?

Yes, you can mix and match motherboards and power supplies from different manufacturers as long as they are compatible in terms of form factor, power connectors, and wattage. It’s important to ensure that the power supply meets the power requirements of your motherboard and other components.


In a nutshell, understanding how many watts your motherboard use is essential for a successful PC build. By considering factors such as installed components, peripheral devices, and intensive tasks, you can optimize power usage and choose an appropriate power supply. Taking steps to manage power demands, such as limiting overclocking and disconnecting unused devices, can contribute to a more efficient system. Ultimately, striking a balance between performance and power efficiency will lead to a smoother and more enjoyable PC-building experience. Happy building!
