Military Class Concept

The perfect trinity of quality, stability and efficiency all exist at one motherboard to meet end user expectations. The MSI Military Class series products provide the long lifespan, unparalleled quality, extreme performance and ultimate efficiency.


Icy Choke
Unbelievable Stability & Lower temperature!!
Compared to the traditional ferrite choke, the Icy Choke provides higher power efficiency and a more stable power supply, which also fulfills power users need for idealized environment with turbo speed and low operating  temperatures.


Solid CAP
10 years long lifespan
For providing the highest quality products, we built-in Solid CAP in the entire Military Class series. This not only makes bursting capacitors a non-issue but also ensures a dramatically extended lifetime and ultra-low ESR.

APS (Active Phase Switching)

Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s motherboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage.
