Yes.
But like I said, instead of using two PSU's (they're not transformers...), just use appropriately heavy wires and keep them as short as feasible.

Thanks. Will do.
But what is the danger/risk of what I have done? I am still a bit confuse of the underlying principle and would like to understand it a bit more to prevent it from happening it again.
