Product overview
Announced on August 20, 2019 for Intel’s refreshed X299 high‑end desktop platform, the Asus Prime X299‑A II targets LGA2066 Core X‑Series CPUs (Skylake‑X/Cascade Lake‑X). Retail availability followed in regions such as Japan from November 2019.Sourceasus.com↗
Positioned as a high_end ATX board, it exists to give creators and power users a stable, feature‑rich HEDT option without ROG extras. It’s genuinely good for expansion/multi‑M.2 (three onboard slots with CPU‑attached NVMe RAID via Intel VROC), overclocking (robust VRM and ASUS AI Overclocking), and high‑speed memory (eight DDR4 DIMM slots up to 256 GB and high OC speeds). Connectivity focuses on wired builds: Intel GbE and USB 3.2 Gen 2 including Type‑C; Wi‑Fi is not integrated. Unique: triple M.2 with VROC for bootable NVMe RAID.Sourceasus.com↗
