Hi guys,
I have 2x 1200W common slot PSU that I want to use on the same mining gear.
I have similar things in the past back in the early days of overclocking over 15 years ago and back then there were some things to do to get this running correctly.
Specifically: * Do I need to connect the grounds from each PSU together? or is that done automatically through the hardware (MB, GPU's, etc.) * Same question for the 12V, should I connect the GND and 12V lines together through a couple of 6 pins connectors. What happens if I do?
The goal of connecting 12V and GND would be to streamline what goes where, so that I don't have to really pay attention too much about how many GPU's should I connect to each PSU's. Maybe I am overthinking it, but I know some current is going through the PCI-E riser boards, and some through the 6-pin Power connect on the GPU itself. But what's the balance? that's highly dependent on the cards themselves.
from my point of view connecting 2 PSU together (linking 12's and GND's lines) would be ideal - though the question of much current will be going through the "bridge cable". If that's too risky (through cable), why don't manufacturers of PDB/Breakout boards don't do DUAL boards with all the linking done through the PCB where it's a lot easier to get through high current?
thanks
