ASRock B850I Lightning WiFi Motherboard - AMD AM5 - DDR5 - Mini ITX

ASRock B850I Lightning WiFi Motherboard brings compact power to Mini ITX builds with support for AMD Socket AM5 processors and modern connectivity.

Designed for the AMD platform, the ASRock B850I Lightning WiFi supports AMD Ryzen 7000, 8000 and 9000 Series CPUs on Socket AM5, delivering compatibility for current and next-generation Ryzen processors. Its AMD B850 chipset provides a solid foundation for desktop performance in a small 170 x 170 mm form factor.

Memory support is modern and flexible with two DIMM slots for DDR5-SDRAM in dual-channel mode, accommodating up to 128 GB of ECC or non-ECC unbuffered memory for demanding multitasking and content creation workloads. The board’s UEFI AMI BIOS (256 Mbit) makes memory and system tuning straightforward.

Storage and expansion options are robust for a Mini ITX board, offering one PCIe 5.0 x16 slot, two M.2 slots (one up to PCIe 5.0 2280, the other up to PCIe 4.0 2280) plus SATA III connectors, supporting up to four drives with RAID 0, 1 and 10 capability. This makes the board ideal for fast NVMe storage and redundant arrays for reliability.

Connectivity is extensive with Wi‑Fi 6E (802.11ax), Bluetooth 5.2, a 2.5 Gigabit Ethernet port powered by the Killer E3100G controller, one HDMI 2.1 output supporting up to 3840 x 2160 resolution, multiple USB ports including USB Type‑C Gen2, and integrated audio via the Realtek ALC1220 codec with 7.1-channel output.

Cooling and customization are well considered for compact builds: the board includes one CPU fan header, one chassis fan header, one water pump connector, and two RGB LED pin headers for lighting. Power delivery features include a single 8-pin EPS connector and standard 24-pin ATX power connection to support high-performance Ryzen CPUs.

Use cases for the ASRock B850I Lightning WiFi include a compact gaming PC with high‑speed NVMe storage and Wi‑Fi 6E networking, a small workstation for video editing or software development using up to 128 GB DDR5, or a media center with HDMI 2.1 output for 4K playback. The board ships with antenna, SATA cables and screws included, simplifying assembly.

If you want a Mini ITX motherboard that balances modern connectivity, PCIe 5.0 readiness, strong CPU compatibility, and advanced networking in a small black chassis, the ASRock B850I Lightning WiFi is a compelling choice.
