Military Class II

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


Hi-c CAP
8X Lifespan than solid Capacitor!!
Insisting on the best stability, MSI utilizes Hi-c CAPs on Military Class series.  Made of the rare element Tantalum, often used on space shuttles and satellites, which sustains very high temperatures and shows an amazingly high electrical conductivity.


SFC
SFC(Super Ferrite Choke).The super Ferrite Chokes use a Ferrite core that is Super-Permeable. Compare with traditional choke, the Super Ferrite Chokes run at a 35 degree Celsius lower temperature. The lower working temperature will enhance motherboard stability.



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.

DrMOS

In order to provide customers stable and high quality products, starting from P45 series motherboards, MSI is leading the industry to introduce the world's most advanced power supply component, DrMOS (Driver-MOSFET), which integrates Driver IC, Top MOSFET and Bottom MOSFET into one chip. Except for its outstanding performance in power saving, DrMOS possesses switch frequency which is 400% faster than traditional MOSFET and has great improvement in stabilizing power supply and voltage control. Even under heavy loading and overclocking conditions, DrMOS can still provide the most stable and efficient power supply and quality.

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. 
 

NVIDIA SLI

SLI technology allows using multiple Nvidia graphics cards in a single computer system with a motherboard equipped with an nForce SLI MCP. Users need an a motherboard with two PCI-Express 16x graphics slots and two matching GeForce graphics cards which are "SLI Ready". Most NVIDIA's PCI-Express graphics cards starting from the 6600 GPU can enjoy the benefits of SLI.

AMD CrossFire

AMD CrossFireX™ is the ultimate multi-GPU performance gaming platform. Enabling game-dominatig power, AMD CrossFireX technology enables two or more discrete graphics processors to work together to improve graphics performance. AMD CrossFireX technology allows you to expand your system's graphics capabilities. It allows you the ability to scale your system's graphics horsepower as you need it, supporting up to four AMD Radeon™ HD graphics cards, making it the most scalable gaming platform ever. With an AMD CrossFireX gaming technology, the traditional graphics limitation exists no more, allowing you to enjoy higher performance as well as visual experience.
