The 4ms Row Power 40 Eurorack Power Supply is a clean, regulated, and protected power solution for Eurorack systems. A single Row Power module can power a small system, and multiple Row Powers can be daisy-chained to power a large system using a single power brick.

Simply plug a laptop-style universal power supply into the Row Power panel and connect your modules via Flying Bus cables or a Bus Stick. You can even daisy-chain multiple Row Powers to use a single power brick for multiple rows. Each row will be independently regulated and protected for ultra-low cross-talk.


  • On/off switch cuts power without interrupting the daisy-chain
  • Row Power 40 (black panel) is suited for up to two Eurorack rows (more than 200HP)
  • Ultra-clean: Each rail is separately regulated with high-grade circuitry
  • Runs cool: Row Power is efficient so it won't heat up itself or your system. Electronics like to chill!
  • Skiff-friendly: very shallow module fits in any case
  • CV/Gate headers for expansion
  • DIY-friendly: PCB pads for blade tabs for power entry, to be used in custom installations where the faceplate is not used
  • Row Power 40: +12 V @ 1.5 A, -12 V @ 1.25 A, +5 V @ 1.5 A
  • Power brick: 2.1 mm barrel, positive center, 15 V - 20 V.
  • 4HP wide, 24 mm deep (0.96"), up to 28 mm (1.1") with power cable
