Same for Nvidia, but here you must only add around 10 - 20w per card to the software readings.
Just to make sure,
So rig of 10x 3070, every card is averaging around 118w + 20w = 138w x 10 cards = 1380w
What about actual computer draw, CPU, etc. how much you usually add there?
I am running those on EVGA 1600w Gold PSUs
