Doepfer a-100 Diy Kit Upgrade

Hay all,

I wanted to add (x2) A-100 Bus Board V6 expansions and just add (x4) 84hp rails. Is this possible with 1 power outlet from a A-100 DIY Eurorack Case Kit. I wanted to know a few things… would this change the voltage or power usage of the power supply? How many expansions am I allowed?

So, yeah it’s gonna be a 4 shelf Eurorack.

Thanks! : )
