Magnetic mark

The magnetic plates can be attached according to different installation orientation of the power supply, giving this power supply the appearances that you like. ( The yellow frame labels the place that can be adjusted. )


Redefine the power supply's fan design and optimize its utility as the power supply's best operational support.

  • rwdimg Material
  • rwdimg Airflow
  • rwdimg Bearing Type


The MEG SILENT GALE P12’s fan blades are constructed by LCP (liquid crystal polymer), a compound that reduces vibration while the fan is running at maximum speed and has a high strength that can withstand thermal expansion.


The fan blades are also carefully crafted to maximize airflow performance, optimized at a 32-degree angle to retain 58% of the airflow.


The HDB (hydro-dynamic) bearing effectively reduces friction noise as well as increases the fan’s life expectancy.
