hmmm... i have 5 G6 racks (& 2 mini cases) with all sorts of various modules, and have never bothered adding up current draw totals or requirements. i just put the mods in more or less logical relation to each other (oscillators -> mixers -> filters -> vcas; with envelopes, lfos & other whatnots placed where they happen to fit; the sequencer subsystem is in its own dedicated case), and have never had any problems, at least none i have ever noticed. guess i've been lucky! i probably should add things up at some point, just to make sure...

yeah, modulargrid made me aware of the problem, though it's not always correct with it's values so i advise anyone to double check figures...

so for an individual who fears the power of electricity, the only way to get more power is to add in a A-100 DIY Kit #1

But note that you need to calculate the total current draw on a module by module basis-stated by manufacturers-not just what would seem to fit the cabinet/rack size. It is best to add the total draw for positive and the total draw for negative together then add 10%. as soon as that approaches your max current draw you need to upgrade.
