Asus ROG StrixB550-A Gaming AM4ATX

Asus ROG Strix B550-A Gaming Motherboard — AMD AM4 ATX board with PCIe 4.0, Wi-Fi 6E, Intel 2.5GbE, dual M.2, and ROG SupremeFX audio for high-performance gaming builds.

The ROG Strix B550-A Gaming targets AMD Ryzen builds that need PCIe 4.0 M.2 storage speed without stepping up to a full X570 chipset. One PCIe 4.0 x16 slot and one PCIe 4.0 M.2 slot give direct high-bandwidth paths to a compatible GPU and NVMe SSD. Intel I225-V 2.5GbE networking and Wi-Fi 6E (802.11ax) cater to both wired and wireless setups. The 12+2 power stage handles overclocked Ryzen 5000 series processors, while BIOS FlashBack allows firmware updates without a CPU or RAM installed. Aura Sync RGB connects to compatible components for consistent lighting.
