Just addressing the '950 (as there seems to be lots of confusion about it):

a) the *wattage* of the '900 and the '950 are *the same*. The '950 splits (NOT
shares, *splits*) the wattage in between the +5V outputs and the +-15V outputs.

b) the '950 power board shipped with the unit has 4ea of the 4-pin (+-15V)
connectors and 6ea of the 6-pin (+5V and +-15V). You are free to use ANY of
these, in ANY combination.

c) even if you do not plug *anything at all* into the 6-pin connectors, the
power supply limits (and this is not changeable) the output *current* to allow
powering around 11 +-15V modules using the 4-pin connectors.

d) even if you don't plug *anything at all* into the 4-pin connectors, the power
supply limits (and this is not changeable) the output *current* to allow
powering around 8 of the newer modules that require the additional +5V (like the
MIDI-CV converter). You could probably power 10 of them if you keep the displays
on the dim side (for examle, in the MIDI-CV converter, 80% of the entite
operating current is in the LCD backlight!).

If you are NOT planning to put a newer module in your system, the get the '900.
If you are planning to use a '600, '650, or '520 then you MUST have a '950.

e) Micromodules use a LOT less current than the 'regular' versions do.
