MSI PRO B850M-A WIFI PZ Motherboard PRO B850M-A WIFI PZ – Next-Generation Style and Tidiness The PRO B850M-A WIFI PZ combines an elegant silver and white design with a rear connector layout that facilitates cable management and creates a clean interior. It features Wi-Fi 7 with EZ Antenna, fast 5G LAN, PCIe 5.0 M.2 and additional PCIe power, making it ready for AMD Ryzen 9000 processors and modern components. Back-Connect Design – a clean interior without cable clutter The PRO B850M-A WIFI PZ relocates key connectors, such as motherboard and CPU power, fan headers, SATA, and other interfaces, to the back of the laminate. This simplifies cable management and gives your computer a neat and tidy look. EZ M.2 CLIP II – Tool-free SSD installation The MSI EZ M.2 CLIP II allows you to install an M.2 drive quickly and without the need for screws or tools. Simply slide the SSD into the slot and press down, and the clip automatically locks it in place. Removal is equally simple – a single flip of the latch and the drive can be removed. It's a convenient, lightning-fast computer upgrade with literally just one finger. Integrated I/O Shield The pre-installed I/O shield simplifies motherboard installation, eliminating the need to manually align the motherboard in the case. Precise alignment ensures perfect port alignment, secure installation, and added protection, enhancing the durability of the entire system. EZ Debug LED – Quickly Diagnose Problems Built-in EZ Debug LEDs instantly pinpoint the source of an issue, so you know immediately which component needs attention. It's a simple way to boot up your PC faster and set up your system hassle-free. EZ Memory Detection LED – RAM Diagnostics The EZ Memory Detection LED instantly alerts you when a memory problem is detected in a specific slot, eliminating the guesswork during diagnostics. This means faster fault detection and a smoother system startup. Direct 8+2+1 Power Design – Stable Power Under Load The 8+2+1 phase digital power design ensures reliable and efficient power delivery to the processor, allowing it to maintain high performance even under prolonged, intense loads. Additional 8+4-pin power connectors prepare the board for demanding tasks and powerful configurations. Optimized PCB Design The laminate design has been refined for higher throughput and faster transfers, resulting in stable, reliable signal transmission. This ensures the board runs reliably and efficiently even with powerful configurations. High-Performance DDR5 Memory Support The PRO B850M-A WIFI PZ supports the latest DDR5 memory, offering a significant performance boost across the board. Thanks to the precise SMT process and MSI Memory Boost technology, the motherboard ensures stable operation and great RAM performance, ready for demanding applications and gaming. Solid Pin Design – Stable CPU Power The 8-pin and 24-pin power connectors utilize a Solid Pin design, which improves conductivity and stability of 12V power to the processor. This allows the board to confidently handle high current loads, maintaining stable operation even under demanding configurations. Grounded Power Design MSI's proprietary, patented power design effectively reduces electromagnetic interference (EMI), improving board stability. It also supports better heat dissipation to the copper PCB layers, translating into lower temperatures and more reliable operation under load. Fast and Future-Proof Storage MSI PRO Series motherboards support the latest drive standards, so you can easily connect ultra-fast storage. This means shorter system and game boot times, faster level loading, and a real advantage in fast-paced gameplay.
