ASUS PRIME B660M-K Intel motherboard

SKU CH-MQBV-ZTRME

Micro-ATX board for 12th Gen Intel Core with two DDR4 slots, PCIe 4.0 and dual M.2

  • CPU TypeIntel Core 12th Gen (LGA 1700)
  • Supports 12th Gen Intel Core processors via LGA 1700 socket
  • Dual-channel DDR4 memory up to 64 GB capacity
  • PCIe 4.0 enables faster graphics and storage bandwidth
  • Two M.2 slots provide flexible SSD expansion options
  • Integrated Realtek 7.1 audio and Gigabit LAN included

Target builder

The ASUS PRIME B660M-K is a Micro-ATX motherboard for Intel Core 12th Gen processors using the LGA 1700 socket. It suits builders assembling a compact Windows 11 ready system with mainstream performance needs. The board provides two DDR4 DIMM slots supporting up to 64GB of memory.

Thermals and power

The Intel B660 chipset runs without active cooling, keeping noise low during typical workloads. Integrated Realtek 7.1 audio and an onboard Gigabit NIC draw minimal power. PCI-E 4.0 and USB 3.2 Gen 1 interfaces operate within standard thermal limits for daily use.

Bundled value

Windows 11 readiness removes the need for a separate OS compatibility check. Dual M.2 slots allow fast storage expansion without extra adapters. Onboard VGA and HDMI ports enable display output directly from supported CPUs, saving a discrete graphics card for basic setups.

Questions about this item

How do I install the CPU into the LGA 1700 socket without bending pins?

Lift the retention arm, align the triangle markers on the processor and socket, lower the CPU gently without pressure, then close and latch the arm. The pins are in the socket, so handle the chip by its edges only.

Will the onboard Realtek 7.1 audio or Gigabit NIC need a driver update after the Windows 11 install?

Windows 11 installs baseline drivers for both, but download the latest Realtek audio and Intel LAN packages from the ASUS support page to enable the full 7.1 channel panel and advanced power management.

Which limit appears first when the VRM runs a 12th Gen Core i7 at full load for an hour?

The 4+2 phase VRM without heatsinks hits its thermal ceiling first, causing the firmware to throttle the CPU multiplier to keep the MOSFETs within safe temperature.
