Good data on the pinouts here: https://edc.intel.com/content/www/us/en/design/products-and-solutions/processors-and-chipsets/alder-lake-s/atx12vo-12v-only-desktop-power-supply-design-guide/2.0/dc-connectors/ https://edc.intel.com/content/www/us/en/design/products-and-... I love the idea of making as many components as possible 12V-only. I think pulling the +5V from the AT-style drive connector and deleting all SATA power connectors is a mistake.
