Better you go for a 1500 Watt and up powersource.
In the case ETH mining comes to an end or another coin (with more power usage) with more income shows up,
you can just go on mining and dont crash your rig.
Dont forget that 3080s take over 40 watt out of the riser. This can cause trouble.
Thanks for the tips. Yeah i was using worst case wattage scenario, its how i arrived close to 1200 watts.
Ill just do the dual psu with the adapter in between and make sure i'm not splitting a single component across two psus, but just evenly distribute things.
I hadnt heard about the 40 watts in the riser with the 3080? Does this mean i should make sure things are a certain way? I already know the pcie cable should be split to the card and the riser (on the same line).
For the rig itself, i think i'm going to switch to the 6 gpu veddha model ($150ish on ebay) https://www.amazon.com/gp/product/B091D2H3F7/ref=ox_sc_act_title_2?smid=A2BTFENBZ612M&psc=1
Though i guess if i were willing to figure it out i could get wood and make my own, lumber in the usa is a bit expensive right now though.
Side note, Eth mining coming to an end is a bit of a concern or the difficulty bomb in july they keep mentioning, but thats another story, i would have to hope that there will be other coins (not in the eth family i guess) that could have "potential future" profit if this comes to pass.
