The ASUS ROG Apex brand extension is reserved for motherboards with the best CPU and memory overclocking capabilities. Since Intel processors tended to overclock better than AMD, Apex remained confined to the Intel platform, until now. ASUS at CES showed off the ROG Crosshair X870E Apex, the first AMD platform motherboard to feature this brand extension. The board features a powerful CPU VRM solution meant for sub-zero overclocking of Ryzen 9000X3D processors that are fully capable of overclocking. It also comes with a 1 DIMM-per-channel memory topology, with just two DDR5 DIMM slots. 1DPC is the most optimal dual-channel topology for memory overclocking.

The topmost M.2 Gen 5 NVMe slot features an elaborate fan-heatsink solution. Right next to the two DDR5 DIMM slots, is a breakout DIMM.2 module that provides additional M.2 NVMe slots. There are a couple of more Gen 4 NVMe slots scattered across the board. The board features an I/O feature-set that's at least as good as the ROG Crosshair X870E Hero. The board draws power from two 8-pin EPS, a 24-pin ATX, and an additional 8-pin PCIe power input. The board is packed to the gills with features professional overclockers would look for, including onboard buttons, diagnostic readouts, a hydrophobic PCB surface treatment, dual-BIOS, and clearly labelled voltage domains.
