 x99

OC Certified is a military class burn-in test for motherboards. Running Prime95 for over 24 hours with a highly overclocked CPU is already a stressing endeavor, but removing all airflow from the motherboard ensures that only the best motherboards survive. If a motherboard can survive this, it can survive any overclocking situation.

MSI Overclocking motherboards are equipped with all the necessary features to make sure you get the most out of your system. From the Enhanced PWM with a large amount of power phases and Thermal Design that give you the best stability, to all the easy features that ensure that you don't have to perform a lot of tricks to get great stability in your quest for performance.


 Z97 MPOWER MAX AC

OC PCB

The OC PCB used for the MSI overclocking motherboards has a completely new design in which 50% more layers are used compared to standard motherboards. This allows us to optimize all traces for overclocking. Power and signal traces are isolated, resulting in higher efficiency and performance and more features can be installed relatively close to each other without causing interference. Every MSI overclocking motherboard is tuned for better stability under extreme circumstances:

  • Increased number of PCB layers
  • Increased humidity resistance
  • Tight weave Fiberglass PCB
  • Increased ESD protection

DigitALL Power PWM

DigitALL Power digitally steers and receives feedback through a DigitALL PWM controller. This allows for pinpoint voltage delivery and lower power consumption.

Thermal Design

Besides inspiring visual awe the MPOWER Thermal Design was developed to deliver the highest cooling potential in the worst situation. Because it is optimized to work in low-airflow situations, it is the ideal cooling to use with your liquid cooling setup.

  • MPOWER thermal design
  • SuperPipe
  • Low airflow
  • Optimized design
  • Clear CPU space
  • Metal screws

Extreme OC Socket Design

What is more frustrating than not being able to properly fit your cooling solution on your motherboard? Through feedback from professional overclockers, extensive research, unique design and the use of Military Class 4 components, we were able to create a lot of space around the socket making sure you can fit any cooling solution you want. Having this much space also makes it easier to insulate the motherboard for use with LN2 or other extreme cooling solutions.


OC Backplate

Mounting your LN2 pot or other extreme cooling solution can be a real hassle when using the stock X99 backplate, because it blocks the necessary screw aperture. That's why MSI created the OC backplate. A low profile backplate which is perfectly flat and gives full access to the screw aperture needed to mount your extreme cooling solution. The OC Backplate generates optimal mounting pressure. This leads to lower CPU temperature and maximizes overclocking results. You can also combine the OC Backplate with the MSI Delid Die Guard for even better mounting and cooling results.
