I already have 1 PC with 1 RTX 3090, I ordered one more RTX 3090 that is coming but I am not sure if I need to change my PSU

my PC specs: i9 10850K,32 GB 3200 RAM,1 RTX 3090 ( 1 extra more will be added)

My current PSU is 850W, will it be enough or I will need to upgrade it?

If I need to upgrade it, is 1200W Enough? Or can I do a cheaper way to buy another 850W and connect it to the new GPU with the same motherboard PC?

Is it safe to have 2 different PSU connected to 2 different GPU with the same PC for mining?

Or you would recommend me to have upgrade the 850W and to have 1 PSU?

You already have one RTX3090 ? Why not look up what's its power draw while mining and then do the math yourself ? In any case you can always downvolt them and replace the PSU if that still doesn't work out.
