ATX motherboard for AMD Ryzen 7000, 8000 and 9000 CPUs with DDR5 up to 256GB, one PCIe Gen5 x16, two PCIe Gen4 x4 M.2, two SATA3, Realtek ALC1220 7.1 audio and Dragon RTL8125BG LAN
Option B850 Live Mixer WiFi
Les versions barrées existent, mais ne sont pas disponibles ici.
The ASRock B850 Live Mixer WiFi is an ATX motherboard built for the AM5 socket. It supports Ryzen 7000, 8000 and 9000 series processors and runs DDR5 memory up to 8000 MT/s across four slots. A 14+2+1 phase VRM with 80A Dr.MOS delivers stable power for long streaming sessions.
This board suits creators who need many USB ports and validated capture-device compatibility. It provides 12 USB 2.0, 8 USB 3.2 Gen1, plus Gen2 and Gen2x2 Type-C ports. Builders wanting a smaller form factor or fewer rear I/O connections should look at a micro-ATX or Mini-ITX alternative.
The maximum supported memory is 256GB of un-buffered DDR5 with ECC across four 288-pin slots in dual-channel mode. If your workload needs that much RAM, this board fits; if 64GB or 128GB is the ceiling, a less expensive B850 model will cover it.
