Users who care about productivity and efficiency can definitely count on the MSI PRO Series to assist you with multitasking and increasing efficiency.
MSI motherboards are designed with advanced hardware and technology, well-supporting the demanding computing usage of gaming and AI. Moreover, we also introduce AI to MSI Center and BIOS, making everything more effortless than before.
provides several categories for you to sync the applications you want to perform and automatically optimizing them to create a comfortable environment.
optimizes networking performance and minimizes latency, providing a seamless online experience.
automatically adjusts fan duty to make sure the system stays in cool, stable and high performance.
is an MSI exclusive feature. It overclocks NPU to improve higher AI performance.
Unleash and sustain the maximum performance with a VRM design built with a total of 7+2+1 digital power phases. With an 8-pin power connector, PRO B850M-G is ready for the challenge of heavy-loading tasks.
The PCB design has been optimized for higher bandwidth and faster transfer speeds, which is also beneficial for reliable circuit transmission.
A huge step of DDR performance enhancement with the latest DDR5 memory. Combines with dedicated SMT welding process and MSI Memory Boost technology, PRO B850M-G is ready to deliver the world-class memory performance.
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.
The 4-pin, 8-pin, and 24-pin power connectors of MSI motherboards are all designed with solid pins. The solid pin design allows for a more stable transmission of 12V power to the CPU, even when handling high current loads.
An extra layer of sponge materials along with corrosive resistance IO Shield to help improve static electricity and reduce electromagnetic radiation noise from the system as well as much more durable compare to traditional IO Shields.
Connect and synchronize with MSI coolers and cases with strategically positioned pin-header locations including a dedicated pump-fan header.
MSI’s premium network solution provides incredible data transfer speed for demanding users.
MSI PRO series motherboards support all the latest storage standards, which allows users to connect any ultra-fast storage device. Start games faster, load levels faster and have a real advantage over your enemies.
Doubling over the previous generation, the bandwidth of a x16 interface can reach 128GB/s.
The advanced SMT(Surface Mount Technology) PCIE slot diminish interference and electrical noise, fully support the PCI-E 5.0 signal.
