Are you using the cable to connect both PSU btw them?

Yes, I am using cable to connect them.

Like the link below:

You may  burned some PCI-e port  on MB if you did not feed all your risers and MB from the separate PSU for sure.

What do you mean dimpsk? is it you mean all risers must power with the same PSU as MB?

Yep, it is necessary. How ya 'd balance GPU supplie does not matter.

Basically we have 2 groups of people


Group 1 - Power MBO, HDD + all riser from one PSU and all the cards from other PSU
Group 2 - Power MBO , HDD from one PSU and all the cards with their riser from other PSU

I Don't know which one is correct, because all options will work until you don't get difference in electric current then it will all go to smoke.

Both work indeed, yes I do both of that scheme. It depends on conditions when we have PSUs with big enough wattage, powering the risers and GPUs from the same source is better. It is about power management, optimizing and risk management.

Make that a Group 3. The best way is to use one PSU for everything. No smokin :-)

There is no  harm in first case at all.
But. Ya can load first PSU with some GPU in addition,
The point was: power supply of MB and all risers should came from the same PSU
