6 GPU Motherboards · 8 GPU Motherboards
We’ve compiled a list of cryptocurrency mining rig 8 GPU motherboards to make hardware selection for builders easier. The list is a combination of manufacturer confirmations as well as from our own mining rig build experiences. GPU mining motherboard manufacturers include ASUS, Gigabyte and MSI.
8 GPU motherboards for cryptocurrency mining
Do note that one or more M.2 to PCI-e adapters are required to reach the 8 GPU capacity. These adapters are simple to install and inexpensive. You can find more information about M.2 to PCI-e adapters, including how to calculate how many you will need, beneath the list of motherboards.

Some of the motherboards above can support 9 GPUs and all obviously support less than 8 GPUs.
* The motherboard we use most often is the ASUS Z370-A, the successor to the Z270-A.
M.2 to PCI-e adapters
Getting to 8 GPUs or more requires at least one M.2 to PCI-e adapter. These adapters transform a M.2 SSD slot into an additional PCI-e slot. Installing them takes just a couple of minutes. To determine how many of these adapters to buy, simply look at how many PCI-e slots the motherboard you are interested in has. Subtract that number from 8. That is how many adapters you need.
The ASUS Z370-A motherboard, for example, has 7 PCI-e slots. That means it would require adapter to reach 8 GPUs. And, since this motherboard has 2 M.2 slots. you could purchase two and go to 9 GPUs.
We have purchased and used the following M.2 adapters:
An 8 GPU motherboard means ‘up to 8 GPUs’
If you’re not going to be running 8 GPUs when you do your initial build, you should still consider if an 8 GPU motherboard might be the right fit. Just because it supports 8 GPUs doesn’t mean your system must have 8 video cards. All of these motherboards can run with up to 8 GPUs.
The most common customer build we do is a 6 GPU mining rig. For those mining rigs, we still go with an 8 GPU motherboard. The cost difference is negligible and it allows for future expansion.
