AORUS B850 AORUS STEALTH

The AORUS B850 AORUS STEALTH is an ATX motherboard based on the AMD B850 chipset for AM5 builds. It supports modern AMD Ryzen 7000/8000/9000 series CPUs and targets users who need high‑speed PCIe and NVMe storage alongside advanced connectivity (Wi‑Fi 7 and 5GbE). The board features a rear‑connect stealth layout designed for cleaner cable management and compact I/O routing.

Memory support includes 4 DDR5 DIMM sockets up to 256 GB with AMD EXPO/XMP support and OC speeds up to 8200 MT/s. Power delivery is handled by a Twin digital VRM design (14+2+2), providing stable power for overclocking and heavy loads. Storage options are generous: four M.2 slots (two PCIe 5.0 via CPU and two PCIe 4.0 via chipset) plus two SATA 6 Gb/s ports. Rear I/O includes USB Type‑C, USB 3.2 Gen2/Gen2x2 (via internal header), HDMI 2.1 and optical S/PDIF — suitable for gaming and workstation setups.
