Socket and Form Factor

The ASUS TUF GAMING B660M-E D4 is an Intel LGA 1700 mATX motherboard built for 12th, 13th and 14th Gen Core processors. It delivers a 10 power-stage VRM on a six-layer PCB with ProCool socket and military-grade TUF components. PCIe 4.0 support covers the primary expansion slot and two M.2 sockets, while Realtek 2.5Gb Ethernet and front USB 3.2 Gen 2 Type-C handle modern connectivity.

Who It Suits

Builders wanting a compact board with strong power delivery and PCIe 4.0 storage for mid-range gaming systems will fit this platform. Users who need more than two M.2 drives, additional full-length PCIe slots, or integrated Wi-Fi should look at larger ATX alternatives. The mATX layout also limits multi-GPU configurations and extensive rear I/O expansion.

Deciding Specification

The single specification that decides fit is the LGA 1700 socket paired with the B660 chipset, which defines the processor generation, memory type and feature set available on this board.

Questions about this item

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

The LGA 1700 socket accepts 12th, 13th and 14th Gen Intel Core CPUs, so any of those generations will install and run.

Can I keep my existing PCIe 3.0 graphics card and M.2 SSD when moving to the PCIe 4.0 slot and two PCIe 4.0 M.2 slots?

Yes, PCIe 4.0 slots are backward compatible, so a PCIe 3.0 GPU and PCIe 3.0 M.2 drive will work at their native 3.0 speeds.

How do I confirm the 2.5Gb Ethernet link is active after I plug in the cable?

Check the LAN LED on the rear I/O panel and verify the connection speed shows 2.5 Gbps in Windows network status or the router's client list.
