MasterWatt Maker 1200 MIJ
Made in Japan, Made to Last.

To celebrate our 25th anniversary, we wanted to pave the way for a future where power supplies surpassed all standards of today and delivered the best possible reliability. Designed in secret in collaboration with a crack crew of 40 engineers, the MasterWatt Maker 1200 MIJ is fully designed, manufactured, and assembled in Japan using unique Murata components. The engineering prowess and dedication that went into the MIJ’s development makes it simply the best power supply we’ve ever made. Made in Japan, made to last.

  • Fully Made in Japan
  • Components by Murata
  • Unique Stacked Transformer
  • Fanless up to 600Ws
  • 10 Year Warranty
  • Exceeds 80Plus Titanium


Murata carefully designed, manufactured and assembled the power supply using enchanced production methods.


40 engineers at Murata designed primary PFC stage chokes reducing heat, and increasing efficiency.


Murata designed a unique stacked transformer that cannot be found in other PSUs. It's cooler and provides more stable power.


Exclusive bearing technology with fanless profile lets the MIJ operate completely silently up to 600Ws.


Three years, forty engineers and collaboration with aerospace and robotics giant, Murata, fully unleashed our R&D capabilities.


Gives you peace of mind on your investment throughout multiple lifecycles and multiple computers.


Most power supplies today convert the 5V and 3.3V from the 12V rail. This can affect the power delivery of the 12V rail under extremely high loads and as such, the MasterWatt Maker 1200 MIJ has separate power conversion for the 5V and 3.3V rails.
