ASRock B860 LiveMixer WiFi ATX LGA1851 DDR5 Motherboard
The ASRock B860 LiveMixer WiFi is an ATX motherboard for Intel Core Ultra Processors (Series 2) designed around the needs of content creators who stream and work with multiple external devices. It combines reliable performance with extensive connectivity options including Thunderbolt 4, multiple USB ports, and Wi-Fi 6E.
Why this product
Thunderbolt 4 and USB4 connectivity
One rear Thunderbolt 4/USB4 Type-C port supports high-speed data transfer and video output up to 8K 60Hz, alongside ten USB 3.2 Gen1 ports for simultaneous peripherals.
PCIe 5.0 and Gen4 storage
One Blazing M.2 slot runs PCIe Gen5x4 for maximum NVMe speed, with two additional Hyper M.2 slots on Gen4x4 and four SATA ports for flexible drive configuration.
Wi-Fi 6E and 2.5G Ethernet
Dual network options cover wired and wireless: Intel Wi-Fi 6E with Bluetooth and a 2.5 Gigabit LAN port ensure stable streaming and file transfer.
12+1+1+1+1 power delivery
Dr.MOS power phases deliver stable voltage to CPU and GPU, supporting overclocking and sustained workloads on demanding processors.
7.1 surround audio with Nahimic
Realtek ALC1220 codec with Nahimic processing and impedance sensing on rear outputs ensures clean audio for content production and streaming.

- SKUASR-3335
- EAN4711581490147
- Fits Intel Core Ultra Processors Series 2 in LGA1851 socket only; not compatible with older Intel generations or AMD processors.
- Accepts standard DDR5 DIMMs (CUDIMM supported) in four slots; maximum capacity 256GB.
- ATX form factor fits standard mid-tower and full-tower cases; verify case supports at least one rear I/O shield opening for Thunderbolt 4 port.
- PCIe slot 2 runs at x4 mode via chipset, not x16; graphics cards and high-bandwidth devices perform better in slot 1.
Best for
- Content creators and streamers who need multiple simultaneous connections for cameras, capture devices, and external storage.
- Users who rely on wireless and wired network flexibility, with Wi-Fi 6E and 2.5G LAN for redundant or concurrent connectivity.
- Builders planning PCIe 5.0 NVMe expansion and requiring three M.2 slots plus four SATA connections.
- Systems requiring professional audio output with 7.1-channel codec and impedance sensing.
Trade-offs
- Compact builds: ATX form factor is larger than micro-ATX or mini-ITX and requires a full-size case.
- AMD-based systems: LGA1851 socket supports only Intel Core Ultra Processors Series 2.
- Second GPU workloads: PCIe slot 2 operates at x4 mode via chipset, limiting bandwidth for dual-GPU configurations.
- Budget-constrained builds: ATX B860 boards with integrated Wi-Fi 6E and Thunderbolt 4 carry a higher cost than stripped-down alternatives.
