Product overview

Launched in January 2022 alongside Intel’s B660 platform for 12th‑gen Core (Alder Lake), the ASUS Prime B660‑PLUS D4 is an ATX LGA1700 board from the Prime family; current CPU support spans 12th, 13th and 14th‑gen via BIOS support lists. As a mainstream B‑series option, it exists to offer a full‑size DDR4 platform with modern I/O at lower cost than Z‑series boards. It suits budget LGA1700 builds and first‑time builders who want expansion/multi‑M.2: four DDR4 DIMM slots (up to 128 GB), a PCIe 4.0 x16 slot for GPUs, three PCIe 4.0 M.2 sockets, and 2.5 Gb Ethernet. Notable extra: a rear USB 3.2 Gen 2x2 Type‑C port (20 Gbps), uncommon for many budget B660 DDR4 boards.
