ES 8 TipTop Happy ending kit

[Subsequent]

Hey there,
i am new to this forum (and modular)
I picked up an es 8 last week at midiamsterdam and I love it
however; I am expiriencing noise on all of my inputs on the es 8
this is in standalone mode (with usb connected) and over adat (whitout usb connected)
when I have no modules connected and only the es 8 there is no noise.
the more modules I introduce the more noise (- 24 db in Ableton)
Could it be that the standard psu from the happy ending kit is not sufficient enough.
Hope someone can help me out here Scratching my head here

kind regards geer
