Hello,
If you are running two PSU (with add2psu for example) on a rig with USB Risers, should you go method A or method B?
Method A : Connect one PSU with the motherboard and all the risers and some GPU. Connect the second PSU only with GPUs
Method B : Every GPUs have to be connected to the same PSU his riser is connected, so connect every (GPU+Riser) on the same PSU. Then connect the motherboard on one of the two PSU
In other words:
Method A : "It is risky to supply the motherboard and some risers with differents PSU. But supplying a GPU and his Riser with differents PSU is ok"
Method B : "It is risky to supply a GPU and the riser connected to this GPU with differents PSU. But supplying some risers and the motherboard with differents PSU is ok"
Or also

I know this has already been discutted but it seems there is a huge controversy in this with this subject. I found a lot of people on both side claiming that the other method is really risky.
Both team have "I have already used method X and no problem" claimers (until problem). So I suppose both configurations actually work but one of them is risky while the other is the actual way to go. But I have no clue wich one
Can someone sure of himself (not just because he always tried something without a problem) help me a bit here?
