Is there any chance of a breakout board that Has ATX and cpu connections on it? would rather use one psu rather then one for mobo and one for the gpus.
Cheers
It's pretty evident that you have literally no clue about what a server PSU means (no offense, but you need to think about it)
What you requested it's technically impossible, they simply don't exist.
You need to convert the voltages from +12V to obtain +5, +3.3, +5VSB, PSON and so on.
This sector it's too hard for the casual investor, the one that should't play with such costly toys
