ASUS PRIME B660-PLUS D4 Intel motherboard

Socket LGA 1700 ATX board for 12th Gen Intel builds

The ASUS PRIME B660-PLUS D4 is an ATX motherboard built around the Intel B660 chipset and LGA 1700 socket. It supports 12th Generation Core, Pentium and Celeron processors and accepts up to 128GB of DDR4 memory across four slots. Two M.2 sockets and a PCI Express 4.0 x16 slot provide expansion for storage and graphics.

Steady throughput on the B660 chipset

The B660 chipset delivers consistent bandwidth for the single PCI Express 4.0 x16 slot and both M.2 connectors during extended workloads. Four SATA ports and one USB 3.1 port maintain stable data rates without the thermal throttling sometimes seen on smaller boards. The DDR4 memory controller sustains rated speeds across all populated slots.

Passive chipset cooling keeps noise low

A heatsink on the B660 chipset dissipates heat without a fan, so the board adds no audible noise to a system. The 24-pin and 8-pin power connectors feed the socket and memory cleanly, and the ATX layout fits standard chassis without special clearance requirements. No I/O shield or extra cables are included in the box.
