I wonder what would be the risk when a psu has for example 400W at one 12A line and i would power one board directly and 3 others with cables? I could use 3mm speaker cables if that helps...

You risk that the weakest part melts.
The power for the 3 others has to go through the PCB from the direct connection to the green terminal then.
burnin already recommended to only connect two boards and use solid wires. I would just follow his recommendations.

I took solid as stable and not static and i still wonder whats the difference. In theory the size of the copper inside tells how easy the electrons can wander inside. So i cant see what difference would there be.

When i think about the setup with the cables... connecting a second board this way would mean that the power would flow completely through the first board until it goes to the second one. In case i overclock the first board would have to take up to 200W and the second 100W. Burnin mentioned that some parts regarding the voltage already is at its limit with such high overclocking/overvolting. So would this setup not be possible for overclocking or are there no parts involved that get at their limits with that overclocking?

As I asked,

Thanks for pointing this out. Thats not a good thing. One would need special PSU's that have different 12A-Outputs since a high wattage PSU with only 1 or 2 such channels used with Y-cables would hurt the miners when i understand it correctly.
Its a good thing i didnt buy more psu's yet but others might have bought wrong ones. Or is there a workaround for this?
