The RX 6800 is a powerful GPU on par with the performance of the RTX 3070 Ti. With the outstanding FPS, and graphics that this graphics card produces, you are probably wondering how much power a card like this eats up.
That’s why in this article we will go through what kind of power consumption this GPU uses, and what PSU you will need, and we are going to put it up against GPUs in the same performance category and compare their TDP.
How Many Watts Does The RX 6800 Use?
The RX 6800 has a TGP or Total Graphics Power of 250 Watts, which is the typical wattage it produces. This is also the average power consumption it uses when gaming. However, when idle The RX 6800 only uses 7 Watts of Power.
The power consumption of your GPU will change depending on what games you are playing, and what applications you are using on your computer.
Another thing to note is the number of monitors you are using with your computer. The more monitors you use the more power your GPU will consume especially when idle.
However, AMD does a good job with its power consumption with multi-monitor use. With the RX 6800, the idle power consumption with a second monitor only increases by one watts, so with two monitors it will have an idle power consumption of 8 watts.
This is pretty good considering that most Nvidia GPUs double their idle power consumption when you add a second monitor to your computer.
With the RTX 3070 Ti, you will see an idle wattage of 10 watts, and you could reach up to 19 watts with a second monitor.
As you can see AMD GPUs are a lot more power efficient than their Nvidia counterparts.
Typically, with an extra monitor, you should expect the idle power consumption to be close to double what it would be with a single monitor, but with this graphics card, it doesn’t.
When you are looking and comparing a GPUs power consumption, you want to look at the GPus TGP or Total Graphics Power, which shows the base power draw you will get when using your GPU for things such as gaming
When talking about power consumption, you might hear the phrase “TDP” used interchangeably with the phrase “TGP”. Essentially TGP and TDP are the same things, but TDP is the total power consumption of a component and TGP is the total power consumption of a GPU specifically.
You should also note that the TGP of a GPU isn’t the true maximum power draw of the specific graphics card, and the power consumption can be increased when computing graphically intensive tasks and while overclocking.
The Rx 6800 has a power limit of 275W which AMD has put in place to prevent damaging your GPU when overclocking.
RX 6800 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 RX 6800.
From this table, you can tell that the RX 6800 is a pretty power-efficient card when compared to similar GPUs.
There is a 40-watt difference between the RX 6800 and the RTX 3070 Ti, which has the same performance level as the RX 6800, and when comparing it to the next level up RX 6800 XT GPU from AMD there is a 30-watt difference.
However, when comparing it to the RTX 3070 you can see that Nvidia wins this one. However, the RTX 3070 doesn’t perform as well in the performance aspect, so it is expected for that card to have a lower power consumption.
Having a high-performance GPU with low power consumption is ideal for many gamers because it can save them money on their electrical bill, which can be put to adding performance to their rig.
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 For My RX 6800?
With the RX 6800, you should look for a PSU that is at least 550 watts. Even then I would go a bit higher and try to get a PSU that is 600 watts that way you have room to upgrade and overclock in the future.
The reason for this is that you never know what you might encounter with power spikes, upgrades, and overclocking.
I would recommend that you get a power supply that is at least 600 watts. That way you have room for upgrades in the future, and if you are planning on overclocking this will provide you with the proper wattage to do so.
Although there are many power supply brands and different qualifications out there I would recommend you go for something that is at least 80 Plus certified that comes from a trusted brand such as EVGA, or Corsair.
This will provide you with power supply hardware that is very reliable and can save you on your energy bill as well.
The reason for this is that a power supply unit that is not certified can take a significant amount of electricity out of your wall that doesn’t do anything. Not only that, but power supplies from a brand that isn’t trusted can damage other parts of your computer, or have underlying issues that you will experience sooner or later.
What’s the Difference Between The RX 6800 and The RX 6800 XT?
When comparing the RX 6800 and the RX 6800 XT you can see that the RX 6800 XT is a slightly upgraded version of the RX 6800.
The RX 6800 XT provides higher FPS, and graphics when gaming. Using an AMD GPU that has XT is similar to using an Nvidia card with a Ti at the end of it.
They are pretty much the same graphics card, however, they have slightly upgraded versions of them with higher clock speeds and better features.
