Sometimes, ATX isn’t big enough for your needs. If you need to go all out and require a motherboard form factor that has the best overclocking potential and serves as the foundation for the most powerful PC you can build, then E-ATX is the way to go. AMD takes the cake when it comes to Micro ATX or ATX motherboards, but Intel reigns supreme in the E-ATX motherboard category.

But E-ATX motherboards can turn out to be incredibly expensive, but some of our top picks are half the price of the current best offerings, while also providing all the sweet bells and whistles for your rig. So, here are our top E-ATX picks for the best motherboards money can buy, while providing the best performance out there.

E-ATX Vs ATX Motherboards

While most PC enthusiasts will preferably go the route of ATX, you’d be surprised to know that EATX motherboards perform incredibly better–that is, if you’re looking to go all out. With EATX, you get a larger motherboard footprint, which can accommodate a plethora of additional slots and ports. Where you can normally find 3-4 PCIe X16 ports with 4 RAM slots on ATX, you get around 4-8 PCIe x16 ports along with 6-8 RAM slots.

EATX also offers additional benefits. Buyers can expect better heat dissipation, a solid gaming experience, and blazing-fast performance in productivity tasks and applications. But it comes with an outrageous price point. So, if you’re looking to get the most out of your gaming and productivity tasks, you can’t go wrong with EATX. But it’ll certainly put a hole in your wallet.
