## Long description

The BIOSTAR B850 SAM5 Micro-ATX motherboard is built on the AMD B850 chipset and supports AM5 (SAM5) processors in a compact Micro-ATX form factor. It offers one PCI-Express 4.0 x16 slot and one PCI-Express 4.0 x4 slot, two M.2 slots for high-speed NVMe storage, both HDMI and DisplayPort video outputs (video output availability depends on the installed CPU), a Realtek ALC897 audio codec with three analog audio ports, and a 2.5 Gigabit LAN port. The board provides a broad set of wired connectivity options including multiple USB 2.0, USB 3.2 and a USB-C port, plus SATA ports and RAID support.
Advantages
This Micro-ATX motherboard combines AM5 CPU support with modern connectivity: PCIe 4.0 expansion, dual M.2 slots for NVMe drives, and multi-gigabit LAN. Integrated video outputs (HDMI and DisplayPort) allow use of CPUs with integrated graphics. The inclusion of USB-C and numerous USB 3.2 ports supports contemporary peripherals and fast data transfer. Hardware RAID for SATA and NVMe and a TPM header add options for storage redundancy and platform security.
Suitable for
Compact desktop builds where AM5 CPU support is required
Home or office PCs needing multiple high-speed storage drives (NVMe + SATA)
Systems that use discrete GPUs or, when CPU has iGPU, need onboard video outputs
Users who require fast wired networking with 2.5 Gigabit LAN

How to use
Install a compatible SAM5 CPU and required cooling according to the CPU and cooler manufacturer instructions, insert memory modules into the appropriate DIMM slots, and mount the motherboard into a Micro-ATX compatible case. Connect power supply cables (24-pin ATX and CPU power), attach storage drives to M.2 slots or SATA ports, and install a discrete GPU into the PCIe x16 slot if needed. Connect front-panel connectors, USB headers, and case audio to the corresponding motherboard headers. Configure BIOS/UEFI settings for boot order, storage RAID (if used), and enable TPM if required.
Usage recommendations
Use quality DDR5 memory modules supported by the AM5 platform, ensure BIOS is updated to the latest version for best CPU compatibility and stability, and use a proper case airflow solution to maintain temperatures when using high-performance CPUs or multiple storage devices.
