it's already available - go to the datasheet view and scroll to the bottom (if you have to) and you will see power consumptinoo by row

remember to leave at least 20-30% headroom

but, why would you use psus with rack warts, especially 4 of them - this will cost you 16hp in rack space and use 4 wall warts and flying busboards

you can probably find a much better solution for all 4 rows for not that much more money

Utility modules are the dull polish that makes the shiny modules actually shine!!!
