After the PSU feeds the motherboard VRM, the VRM then changes that voltage from 12v to something like 1.25v for the CPU, and that is where Z370 motherboards generally fall short (except high-end). GIGABYTE has designed all of their Aorus Gaming Z390 motherboard to handle the increased requirements.

DRAM: If you go to GIGABYTE's website you will find a tab under "Support" for "Support List". Under that you will be able to download individual lists for each motherboard, such as the
