ASROCK B850M PRO-A WIFI

ASROCK B850M PRO-A WIFI
The ASROCK B850M PRO-A WIFI motherboard is built on the AMD B850 chipset and features an AM5 socket, ensuring support for AMD Ryzen 7000, 8000, and 9000 series processors. It has four DDR5 RAM slots with support for frequencies up to 8000+ MHz when overclocked. The Micro ATX (mATX) format allows for installation in more compact PC cases while maintaining sufficient expandability and a robust design.
Key features of the ASROCK B850M PRO-A WIFI motherboard
- 8+2+1 Dr.MOS power stage design ensures a stable power supply for AMD Ryzen processors
- Support for DDR5 memory up to 8000+ MHz (OC) increases overall system responsiveness
- Reinforced steel PCIe 5.0 ×16 slot is ready for modern graphics cards
- Blazing M.2 PCIe Gen5 ×4 interface offers transfer speeds of up to 128Gb/s for SSDs
- Wi-Fi 6E 802.11ax module provides fast wireless connectivity in the 6GHz band
- Dragon 2.5Gb/s LAN card optimises data flow for smooth online gaming
Stable power and memory
The power stage, with its 8+2+1 phase configuration and Dr.MOS technology, provides the processor with a stable and smooth power supply, which is key to maintaining high performance even under heavy loads. The board features a six-layer PCB that optimises signal paths and thermal properties. Support for Intel XMP and AMD EXPO profiles makes it easy to set the optimal parameters for memory modules to achieve maximum system throughput.
Fast interface and storage
For graphics cards, there is a reinforced steel PCIe 5.0 ×16 slot that can handle heavier models and ensures maximum throughput for future hardware. Storage can be installed in one Blazing M.2 slot with a PCIe Gen5 ×4 interface for extremely fast SSDs with transfer speeds of up to 128Gb/s. Two additional Hyper M.2 slots use the PCIe Gen4 ×4 interface, providing ample capacity for the system and data. Four SATA III connectors are available for traditional drives.
Connectivity and networking
Network communication is handled by a 2.5Gb LAN Dragon controller optimised for low latency in online gaming and content streaming. Wireless connectivity is provided by a Wi-Fi 6E module with 6GHz band support and Bluetooth 5.2, which eliminates interference in crowded environments. The connector line-up includes rear USB 3.2 Gen 2 ports, including a modern USB-C interface, and HDMI 2.1 and DisplayPort 1.4 graphics outputs for connecting high-resolution monitors up to 4K at 120Hz.
