Whether your work involves a lot of heavy graphics-related work or you are an enthusiast trying to build a high-end gaming computer, having a motherboard that supports a multi-GPU setup will do wonders for you.

If you don’t know how it works, here is a quick answer:

NVIDIA uses a Scalable Link Technology or SLI that can link more than one NVIDIA GPU together, giving you more processing power at once. The more graphics cards you add, the more power you can use.

While SLI technology is available on a plethora of motherboards — from budget to expensive, the only thing that varies is the number. There are 2-way SLI, 3-way SLI, and 4-way SLI motherboards available, and depending on the power and performance you need, you can pick any one of them.

To help you pick the right one, I have made a list of the 5 best motherboards for SLI in 2022.

Best SLI Motherboards in 2022

While SLI motherboards are available in different form factors like ATX, micro-ATX, etc; your best bet is to consider ATX or bigger motherboards as they offer better connectivity and expansion options for multiple graphics cards.

Another point to keep in mind while buying an SLI motherboard is to check the CPU socket. Multiple graphics cards would be of no use without the support of a powerful CPU. So in order to make sure your computer is performing perfectly, you should invest in a high-end CPU.

In this post, I have categorized each of these motherboards into — Top Pick, Runner-up, Micro-ATX, Value for Money, and Budget.

Having said that, here are the 5 best motherboards for SLI in 2022 and everything about each one in-depth!
