Guys, this is analog, so all specs are just guide lines....  Of
course, I am not a technical expert, but in my practical experience,
the more amps, the merrier....


The bottom line is stability - even with power supplies operating
within the specs of the necessary current draw of the modules in your
system, the issue is really, "How stable do you want your oscillators
to be?"

If you really want VCO stability, you really want a separate PSU for
the VCOs, so that when your Woggle bug is wigging out with its LEDs,
there will be no microscopic pitch deviation due to the additional
current draw from the LED show.

In my system, I have a separate 1.5A PSU specifically for the
VCO/WFCs.  The rest are on a two other PSUs, isolating the VCOs from
any CV antics that I might conjur up in a patch.  Thie way, no changes
in the current draw resultant from LEDs of the other modules will
effect the VCOs tuning in any way.

The bottom line is that there is really not too much PSU amperage that
you can throw at your system - it is more about what you want to
afford....  But VCO stability is the major guideline.
