Direct 6+1+1+1 POWER DESIGN

Unleash and sustain the maximum performance with a flagship VRM design built with a total of 6+1+1+1 digital power phases. With an 8 pin power connector, PRO B860M-B WIFI is ready for the challenge of high-end processors.

DDR5 MEMORY SUPPORT WITH HIGH PERFORMANCE

A huge step of DDR performance enhancement with the latest DDR5 memory. Combines with dedicated SMT welding process and MSI Memory Boost technology, PRO B860M-B WIFI is ready to deliver the world-class memory performance.

Transient Voltage Suppressors (TVS)

Transient Voltage Suppressors (TVS) are safety devices used to protect against excessive voltage. All motherboard models of MSI are equipped with TVS. When the voltage abnormally rises, the TVS switches from a high-resistance state to a low-resistance state, diverting the excessive voltage to ground. This helps prevent circuit damage caused by high voltage.
