Well, no, that would be connecting ground to the "live" wires. What you have done is wired the supplies in parallel.
Very simply, you have halved the power draw from each PSU (assuming single rail, equal resistance, etc.)
However, if the two power supplies do not provide the same voltages, you will be inducing a voltage potential across a strand of wire. I am sure that this potential is minimal, and modern power supplies and computer components will probably cope, but this is still quite undesirable.
Simply using the two independently would be better. (Even though your system does not need it.) As long as you distribute the power draw intelligently, you will end up with the same goal
as parallel psus (half power draw on each psu) without the the drawbacks.
Essentially, you had two directions to go in, and you have chosen the poorer one.Edited by Sun - 1/13/11 at 1:43pm
