This is a Z390 ASUS ROG MAXIMUS XI EXTREME motherboard, which I purchased as a manufacturer reconditioned “OPEN BOX” item from NewEgg (still sealed), and never opened nor put it into a build. The ROG Maximus XI Extreme is a fully-loaded, flagship EATX form factor motherboard, compatible with Intel’s 9th and 8th generation LGA 1151 processors and DDR4 SDRAM.
