How Many GPUs Can a Motherboard Support?

One of the most important components of a computer, the graphic card (GPU) impacts the smoothness of the performance of the computer. A GPU is especially important for activities including mining and gaming and can be critical towards the experience that the user gets. That is why users today are more aware of the GPUs when they want to switch to more capable versions of PCs that perform the best.

How Many GPUs Can a Motherboard Support?

Many people have a question “How Many GPUs Can a Motherboard Support?”, especially when they want to upgrade their GPU card configuration. The majority of the motherboards will support 6 GPUs. However, it may depend on the number of PCIe slots that the motherboard has. Therefore, for a computer with a CPU, storage, memory, and a motherboard, there can be a maximum of 6 GPUs. However, just like other things, there can be different kinds of motherboards as well. The latest motherboard by a company called Asus accommodates 20 graphic cards. Such a motherboard and CPU is more suitable for resource-intensive activities including mining.

Putting Multiple GPUs In A Motherboard

Technically, it is possible to have 2 GPUs in a single motherboard. But the GPUs will function independently if they are different and are not linked together through a GPU array. When you want to use dual or multiple graphic cards, your PC should have AMD or Nvidia Technology. Any of these technologies can link the multiple GPU cards so that they can provide a single output. The two technologies have different names. For AMD, it is called Crossfire, while for Nvidia it is known as SLI. However, no matter what solution you are choosing, you should have a motherboard that is compatible with multiple GPUs and has the necessary PCI slots for it. The majority of the computers have motherboards with an expansion slot and capacity. However, if you aim to use more than 2 graphic cards and GPUs, you should try to know more about the manufacturer of the motherboard and find out with it whether three or more GPUs can be added to the PC or not.

Adding 2GPUs to the Motherboard

First, you need to add the video card to the provided slot in the motherboard. Press the card down gently and you will hear a “snap” sound. You can also screw the GPU to the motherboard as there is a metal plate available at the end of your graphic card. The same process should be carried out for the second GPU and video card. Once the two cards have been added, you need to power them. If the two GPUs are having different connectors, they need to be connected with power separately. In other cases, you can connect power to only one of them

Why Have Multiple GPUs

There can be certain unique benefits of having dual or multiple GPUs in a motherboard. When you have multiple GPUs on your PC and motherboard, it can provide for much better performance and improved video graphics. With multiple graphic cards available, the games can also be run at higher resolutions on a computer. There are certain expenses associated with having an extra GPU on a computer. If you have a budget for it, you can always go for more GPUs as it will improve your experience on your computer. More GPUs and more powerful processors and computers are already being used for certain activities such as mining.

However, if you do not play any video games on your computer or if you do not mine for cryptocurrency, you do not need a computer having multiple graphic cards. In such a scenario, having dual or multiple GPUs will be a waste of money or time as there would be no difference in performance. A motherboard may also not be able to carry multiple GPUs if it is not compatible with it. Therefore, you may also have to upgrade your motherboard as well to accommodate multiple cards. It would further increase the investment, which is not required when you do not want a greater performance.


Different kinds of motherboards have different compatibilities and capabilities. It is not difficult to find a motherboard that has multiple PCIe slots and which can gather and run multiple GPUs. However, if you are not sure of the configuration, you can talk with the manufacturer and know more about the compatibility of the GPU.
