ASROCK B850M Rock WiFi
ASROCK B850M Rock WiFi
The ASRock B850M Rock WiFi motherboard serves as the cornerstone for building a PC with AMD Ryzen 7000, 8000, and 9000 series processors. It connects the individual hardware components and facilitates their communication and stable power supply in a compact mATX format. The board features an AMD B850 chipset with an AMD AM5 socket for home and gaming use. It supports fast DDR5 RAM and the PCI Express 5.0 interface for smooth system performance. The board includes connectors for both standard and addressable RGB LED strips and compatible accessories. Users can synchronise lighting effects using Polychrome RGB Sync or SignalRGB software. Various settings make it easy to customise the colour scheme of the entire PC build to your own liking.

Number of RAM slotsKey features of the ASRock B850M Rock WiFi motherboard
- Based on the AMD B850 chipset with an AMD AM5 socket in an mATX format
- Features two DIMM slots with support for DDR5 memory
- Connectivity is expanded by one PCIe 5.0 x16 slot and a second PCIe 3.0 x16 slot
- Storage consists of two fast M.2 NVMe slots and four SATA III ports
- Network connection is handled by a fast Dragon 2.5G LAN card and a Wi-Fi 6E module
- The power delivery system uses a stable 6+1+1 phase design
- An integrated Post Status Checker facilitates quick diagnostics
Stable power and high energy efficiency
The power delivery system uses a 6+1+1 phase configuration with integrated Dr.MOS circuits for VCore. These components optimise voltage for the processor and exhibit better thermal efficiency than traditional MOSFETs. The motherboard is built on a 6-layer PCB, which contributes to lower temperatures and stable signal transmission. This design provides greater energy efficiency, which is particularly noticeable when overclocking DDR5 RAM with XMP or AMD EXPO profiles.
Fast storage
The board features two slots for M.2 NVMe SSDs with a Toolless SSD Installation function for tool-free assembly. The first Blazing M.2 slot supports the PCIe 5.0 x4 interface with a transfer speed of up to 128Gb/s. The second Hyper M.2 slot works with the PCIe 4.0 x4 interface at speeds of up to 64Gb/s. For traditional hard drives, the board offers four Serial ATA III connectors with a speed of 6Gb/s and support for RAID 0, 1, and 10 disk arrays.
Advanced wireless connectivity options
Wireless connectivity is handled by a Wi-Fi 6E module, which also operates in the 6GHz band. This solution delivers higher network capacity and lower latency. The integrated Bluetooth 5.3 interface provides easy connection for wireless peripherals and accessories without the need for cables. A wired network connection is provided by a Dragon network card with a speed of 2.5Gb/s.
Design features of a modern motherboard
The main PCIe 5.0 x16 slot is steel-reinforced, increasing stability and mechanical resistance when installing heavy graphics cards. An aluminium heatsink ensures effective heat dissipation from the power delivery components. The cooling system is complemented by 4-pin connectors for fans and a water pump, for which the board automatically detects PWM or DC control mode. The board includes an integrated rear I/O shield for easier installation into a PC case. The Post Status Checker diagnostic system uses LEDs to instantly show the status of the CPU, memory, graphics card, and boot drive during startup. The BIOS Flashback function lets you update the firmware with only a power supply and a USB drive connected.

Choosing a motherboard
When choosing a motherboard (also known as a mainboard), it's important to pay close attention to the motherboard's socket type, format, and chipset. These parameters are among the most crucial and ensure the board's compatibility with the processor, expansion cards, and other components. The specific socket will determine the choice of a suitable processor, while the remaining connectors will dictate the selection of other components for your future computer.Specifications
