NO!. SMPSUs do not like being run in parallel (unless
designed to be
used like that). One PSU will end up attempting to supply all the
current and the other PSUs may not like having voltages applied to
their outputs.
And once the first one drops dead, the next
most "powerful" one repeats the process.
Proof by "induction" left as an exercise :-)
*giggle* OK, ok, thought it was best to ask.... *laughs manically*
Presumably, if one could a) tolerate the voltage drops and b) find massive
diodes (many amps for the intended application in an 11/750), it could be
done safely. Please feel free to correct me if I'm wrong.
I thought this, then laughed at the size of the diodes. 135A total for
the 5v, 85A for the 2.5v lines...
