RTX 3080 Ti GPU with a power consumption of 350 watts

You managed to get your hands on an RTX 3080 Ti, and are looking to build a high-performance PC.

Now that you are able to play games at high performance and stunning graphics, you need to figure out if your power supply can handle this card.

You’ve come to the right place. Here is a quick guide on the power consumption of the Geforce RTX 3080 Ti Graphics card.

How Many Watts Does an RTX 3080 Ti Use?

The RTX 3080 Ti has a TGP or Total Graphics Power of 350 Watts, which is the typical wattage it produces. When gaming you should also hit around 340 Watts. However, when idle the GPU should only produce around 16 Watts of power.

The wattage that this card uses can change depending on how powerful your gaming setup is, as well as the types of games and tasks you are doing.

For example, if you use more than one monitor expect your graphics card to have a higher idle power consumption.

Typically, with an extra monitor the idle power consumption will be under double what you would see with just one monitor.

In this instance, the Geforce RTX 3080 Ti graphics card will produce around 26 Watts of power when idle in a dual monitor setup.

When looking at a GPU’s power consumption, you want to look at the TGP (Total Graphics Power) because this shows the maximum power draw you will usually get when using your GPU for intensive tasks such as gaming.

Idle power consumption of 16 watts

You might also hear the phrase “TDP” which can be used interchangeably with TGP. The difference is essential in that TDP is the total power consumption of a component, and TGP is the total power consumption of a GPU specifically.

However, it is not actually the true maximum of the graphics card. The true maximum of the RTX 3080 Ti is around 375 Watts, but this only happens, when you see a spike in your performance. These power spikes only last a few seconds and will go back down to the max baseline level which in this case is only 350 watts.

This power draw can also be met when you overclock your system.

RTX 3080 Ti Power Consumption Compared to Other GPUs

The GPUs power consumption is compared using TGP. It is essential to know and compare your graphics cards to other similar models because it will help you get a grasp on the amount of power your system is going to use.

Here is a comparison of a few graphics cards that are around the performance range of the RTX 3080 Ti.

RTX 3080 Ti350 Watts
RTX 3090350 Watts

As you can see from this table, the RTX 3080 Ti has a very high power consumption compared to other GPUs. Up there with both the RTX 3080 and RTX 3090.

If you want to compare more graphics cards on their power consumption and TGP I have provided a database where you can look at dozens of different GPUs and their power consumption, that way you don’t have to do the research yourself.

Check out the Database.

I have also provided the average power consumption when gaming, as well as the average power consumption when idle, that way you can get a better understanding.

What Power Supply Do I Need to Use For an RTX 3080 Ti?

I would recommend that you try to get a power supply unit that is 850 watts. If you go on Nvidia’s page you can see that they say that the 3080 Ti would be able to run on a 750-watt power supply, however, that is the bare minimum.

850 watt power supply to support RTX 3080

When purchasing a power supply for your computer you want to keep in mind that every piece of hardware in your system also has a certain level of power consumption, not just your graphics card.

Although not as powerful as a graphics card, all of these little components add up and can exceed the wattage of your PSU very quickly.

That’s why you want to be safe and grab a PSU that has around a 20% increase in extra wattage than you planned for your system.

By doing this you will not only know for sure that your PSU will be able to support powering your whole system but it will also be safe from any power spikes that happen when you are gaming.

If you also want to save on your electricity bill, then you should purchase a power supply that is at least 80 plus Bronze certified, with the best rating being 80 plus Gold certified.

RTX 3080 Ti FAQ

What CPU is Best for The RTX 3080 Ti?

You should purchase either a Ryzen 9 or an Intel i9 as these CPUs are on par with the performance of the RTX 3080 Ti.

What Temperature Should The RTX 3080 Ti Run at?

The RTX 3080 Ti should run at 90 degrees Celsius or less. If your 3080 Ti runs at 100 degrees celsius or more, then you risk damaging the graphics card.
