4MS Row Power 40 Eurorack Power

4MS’s Row Power 40 module is an extremely clean power solution for Eurorack modular systems. The module connects easily to 4MS’s Power Brick and provides 40W of power to up to two Eurorack rows (just add flying bus cables; not included). 

Row Power 40 Features

  • Two power jacks for daisy-chaining multiple Row Powers: a common laptop-style power brick could power 3-5 rows (typical)
  • On/off switch cuts power without interrupting the daisy-chain
  • Row Power 40 is suited for up to 2 typical Eurorack rows
  • Ultra-clean: Each rail is separately regulated with high-grade components
  • Runs cool: Row Power is efficient so it won't heat up your system. Electronics like to chill

  • CV/Gate headers for expansion
  • Blade tabs for power entry, to be used in custom installations (e.g. if the 4HP panel is not used)
