Product overview

ASRock’s B450 Pro4 arrived on July 31, 2018, as part of AMD’s B450 (400‑series) platform for 2nd‑Gen Ryzen “Pinnacle Ridge” on socket AM4. ([asrock.com](https://asrock.com/news/index.cn.asp?iD=4026&utm_source=openai))

Positioned as a mainstream B‑series ATX board, it exists to deliver affordable overclocking and solid I/O without X‑series pricing. ([pcworld.com](https://www.pcworld.com/article/402322/amd-launches-ryzen-b450-chipset.html?utm_source=openai)) It offers four DDR4 DIMM slots, dual M.2 (one PCIe 3.0 x4), PCIe 3.0 expansion, Gigabit LAN, USB 3.1 Gen2 Type‑A/C, and no onboard Wi‑Fi—well‑suited to first‑time builders and expansion/multi‑M.2 use cases. Notable: the secondary M.2 slot supports 22110‑length SSDs. ASRock does not mark it discontinued as of July 2026. ([asrock.com](https://www.asrock.com/mb/AMD/B450%20Pro4/))
