## Long description

ASRock B850 LiveMixer WiFi is an ATX motherboard for AMD Socket AM5 processors, compatible with Ryzen 7000, 8000 and 9000 series. It supports DDR5 memory up to 256 GB across four DIMM slots and provides extensive storage and connectivity options including PCIe 5.0 M.2, PCIe 4.0 M.2, SATA III, multiple USB ports and Wi‑Fi 7. The board is designed for content creators and streamers who need stable performance, broad device compatibility and versatile expansion.
Advantages
The LiveMixer WiFi motherboard combines an optimized 14+2+1 VRM with Dr. MOS power stages, Hi‑Density CPU power connectors and an upgraded 20K 1000µF capacitor to improve power stability, thermal performance and long‑term reliability. An 8‑layer PCB and robust cooling features — including large aluminum heatsinks, M.2 heatsinks and PWM/DC fan support — help sustain high performance under load. Connectivity is extensive: 23 USB ports, dual PCIe x4 slots, front-panel USB 3.2 Gen2x2 Type‑C header, 2.5 Gb/s LAN and Wi‑Fi 7 with Multi‑link Operation for low latency and high throughput. Onboard audio with Nahimic and Lightning Gaming Ports target clear communication and reduced input lag for gaming and streaming workflows.
Suitable for
Content creators and streamers using multiple capture devices and peripherals
High‑performance gaming PCs with overclocking
Workstations that require fast NVMe storage (PCIe Gen5/Gen4)
Systems needing advanced wireless networking (Wi‑Fi 7) and 2.5 GbE LAN

How to use
Install an AM5 CPU, populate DDR5 modules in matched slots per the manual, and mount M.2 SSDs under the provided heatsinks using the toolless mechanism. Connect the power supply to the Hi‑Density CPU and 24‑pin connectors, attach case fans to PWM/DC headers and connect thermistor cables if customized thermal monitoring is required. For storage, install PCIe Gen5 or Gen4 M.2 drives in the designated sockets and configure RAID in BIOS if needed. Use the UEFI or ASRock utilities to enable XMP/EXPO memory profiles and to set fan curves via Fan‑Tastic Tuning.
Usage recommendations
For stable overclocking and long‑term reliability, use a quality power supply that can deliver sufficient current to the Hi‑Density connectors, ensure adequate case airflow for M.2 and VRM cooling, and keep motherboard BIOS and Wi‑Fi drivers up to date. Use compatible XMP/AMD EXPO memory modules and follow the manual’s slot population guidelines to achieve optimal DDR5 performance.
