Row Power 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. Row Power modules run cool and provide safe, clean and quiet power to your modules. In a typical system, a single Row Power 40 module can typically power 150-250HP of modules.


  • Two power jacks for daisy-chaining multiple Row Powers: a common laptop-style power brick typically powers 300-500HP.
  • On/off switch cuts power without interrupting the daisy-chain
  • Row Power 30 (white panel) provides more than enough power for 104HP of modules (sometimes up to two 84HP rows).
  • 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
