Compact AM5 platform for Ryzen builds

This Mini-ITX motherboard uses the AMD B850 chipset and Socket AM5 to support Ryzen 9000, 8000 and 7000 series processors. Two DDR5 slots accept up to 128 GB of memory running at speeds up to 8400 MT/s when overclocked. A single PCI Express 5.0 x16 slot and two M.2 sockets provide high-speed expansion in a small footprint.

80 A power stages and thermal guards for steady

The 8+2+1 phase VRM uses 80 A smart power stages to deliver clean current to the CPU during extended workloads. Dedicated VRM and M.2 thermal guards dissipate heat across the board surface, helping maintain consistent frequencies without throttling when the system runs under sustained load.

EZ-Latch mechanisms simplify component installation

M.2 EZ-Latch and PCIe EZ-Latch let you secure drives and expansion cards without screws, while Wi-Fi EZ-Plug makes antenna attachment straightforward. The Mini-ITX layout keeps cable routing tight, so builders should verify case clearance for the 288-pin memory modules and the USB-C front-panel header before assembly.

Questions about this item

Will the 80A Smart Power Stage and VRM Thermal Guard keep the board cool and quiet under all-day loads?

The 8+2+1 phase design with 80A Smart Power Stages and VRM Thermal Guard is built to handle sustained Ryzen 9000, 8000, or 7000 series workloads without throttling, keeping temperatures in check for quiet operation.

Which DDR5 memory kits and CPU coolers must I already own to use this Mini-ITX board?

You need DDR5 modules (up to 8400 MT/s OC, 128 GB max across two 288-pin slots) and an AM5-compatible cooler; the socket uses the same 1718 mounting pattern as previous AM5 boards.

Can I reuse my PCIe 5.0 graphics card and existing 2.5GbE switch with this B850I AORUS PRO?

Yes, the single PCIe 5.0 x16 slot runs at full speed for current GPUs, and the onboard 2.5GbE LAN connects directly to your existing 2.5GbE switch without extra adapters.
