Coolermaster Real Power Range

Power supply units

Crucial Ballistix PC6400


Coolermaster have, at times, been considered the kings of top of the line case manufacturing; thanks in part, to their popular Stacker range of chassis. In recent years though, Coolermaster have branched out into other areas, and attempted to apply their industry defining style and panache to other product types. Today I’ll be testing 3 of CM’s top of the line Real Power modular PSUs; lets see if they can live up the Coolermaster name.



  • World’s first six +12V rails for better power distribution in Quad-SLI and 2 ways server system
  • Modularized cable design to eliminate clutter and improve airflow inside the chassis.
  • Four 6 pin / Two 8 pin PCI-e connectors offer great future upgrade ability
  • Compliance with the newest Intel standard ATX 12V V 2.3
  • Compliance with the newest SSI standard EPS 12V V2.92
  • Ultra-silent operation with intelligent 135mm fan speed control (< 16dBA)
