About the MSI MAG B550M MORTAR MAX WIFI

PREMIUM HARDWARE DESIGN | OPTIMIZED FOR WATER COOLING

Designed to support the most popular All-In-One & customized water cooling solutions on the market. A dedicated water pump PIN header supports up to 3 amp, giving you full control of the water pump speed. A clearly marked 'keep-out-zone' allows for easy and safe installation and a perfect fit.

THERMAL SOLUTION FOR MORE CORES AND HIGHER PERFORMANCE

With more cores' processors, thermal and power design is more important to make sure the temperature keeps lower. MSI extended PWM heatsink and enhanced circuit design ensures even high-end CPU to run in full speed with MSI motherboards.

M.2 SHIELD FROZR

World's fastest SSDs can start to lower performance when getting hot. Part of the motherboards heatsink design, M.2 Shield Frozr is the next generation M.2 thermal solution to avoid this by offering the best thermal protection to make sure that SSD maintains maximum performance.

With MSI M.2 Shield FROZR

  • Prevents throttling
  • Maximizes drive performance
  • Higher maximum SSD speeds

Normal M.2 SSD | ENHANCED PERFORMANCE
