The Advanced Technology Extended, or ATX form-factor, is the name for a particular specification of motherboard and power supply that, when debuted in 1995, built upon older designs to create a more unified and capable standard for the industry.

EATX is defined as 12 inches tall by 13 inches wide, if it’s even defined at all, while a standard ATX board is 12 inches tall and 9.6 inches wide. … Making an ATX board taller allows more room for chipset cooling and PCIe slots, which are primarily useful for multi-GPU setups, which are increasingly rare. EATX is bullshit wannabe half-specification, not a real form factor. At least, not the way it’s being treated right now. It doesn’t mean anything. The name “EATX” implies a standard, but it’s not a standard, it’s a free-for-all. That’s not even getting into EE-ATX, or Enhanced Extended Advanced Technology eXtended, which is actually a name
