Intel LGA 1700 ATX motherboard

The ASUS PRIME B660-PLUS D4 is an ATX motherboard built around the Intel B660 chipset and LGA 1700 socket. It supports 12th, 13th and 14th Generation Intel processors and provides a foundation for desktop builds that need expansion room and modern connectivity.

Builders who need three M.2 slots and 2.5Gb Ethernet

This board suits users who want three M.2 slots for storage, PCIe 4.0 expansion, rear USB 3.2 Gen 2x2 Type-C and front USB 3.2 Gen 1 Type-C headers, plus Realtek 2.5Gb Ethernet. Builders requiring integrated Wi-Fi, additional rear USB ports or a smaller micro-ATX form factor should consider other options.

Eight power stages and VRM heatsink for mid-range

The eight power stages and VRM heatsink deliver stable power for mainstream processors, while the M.2 and PCH heatsinks keep storage and chipset temperatures in check. Heavy overclocking on high-core-count chips or sustained all-core workloads may exceed the cooling headroom provided.

Questions about this item

Which Intel processors fit the LGA 1700 socket on this B660 board?

The socket supports 12th, 13th and 14th generation Intel CPUs, so any processor from those families will install directly.

Will my current PCIe 3.0 graphics card and storage drives work with the PCIe 4.0 slots and three M.2 connectors?

Yes, PCIe 4.0 slots are backward compatible, so PCIe 3.0 cards and drives will operate at their rated speeds.

How can I verify the 2.5 Gb Ethernet port is running at full speed after assembly?

Check the link speed in the OS network adapter settings or run a local throughput test; a sustained transfer above 1 Gbps confirms 2.5 Gb operation.
