Micro ATX LGA 1700 board for 12th Gen Intel

This Micro ATX motherboard uses the Intel B660 chipset and an LGA 1700 socket to support 12th Gen Intel Core, Pentium Gold and Celeron processors. It provides four DDR4 slots with a maximum capacity of 128GB and runs memory speeds up to 4800 OC. The board includes 2.5Gbps LAN, 7.1-channel audio and a rear USB 3.2 Gen2x2 20Gbps Type-C port.

Suits DDR4 builders needing 2.5Gbps LAN

Builders who want a compact board with wired 2.5Gbps networking, high-speed rear USB-C and front-panel USB 3.2 Gen 2 Type-C support will fit this model. Users requiring more than two full-length PCIe x16 slots or more than six SATA ports should look at larger form factors. The two M.2 interfaces and six SATA III ports cover typical storage needs.

Extended VRM heatsink handles sustained multi-core

The extended heatsink over the power phases keeps temperatures in check during long compile, render or compute sessions. PCIe 4.0 on the primary x16 slot and PCIe 3.0 x4 on the second x16 slot maintain consistent throughput for GPUs and high-speed add-in cards without throttling. Fan headers allow targeted airflow over the VRM area for heavy workloads.

Highlights

  • Supports 12th Gen Intel Core processors on LGA 1700 socket
  • Up to 128GB DDR4 memory with speeds to 4800 (OC)
  • PCIe 4.0 x16 slot for modern graphics cards
  • 5Gbps LAN plus Realtek ALC1200 7.1-channel audio
  • USB 3.2 Gen2x2 20Gbps Type-C on rear I/O
