ASUS PRIME B660M-K D4 LGA 1700 Micro-ATX Motherboard

The ASUS PRIME B660M-K D4 targets builders who want a current LGA 1700 platform without unnecessary complexity. It runs the Intel B660 chipset in a Micro-ATX frame and keeps a clear upgrade path across three Intel generations, with dedicated audio PCB layers and LANGuard-protected networking.

Key Highlights:

• Three-Generation CPU Support: The LGA 1700 socket accepts Intel Core 14th, 13th, and 12th Gen chips plus Pentium Gold and Celeron, keeping processor options open.
• High-Speed DDR4: Two DIMM slots take up to 64GB at speeds reaching 5333MHz (OC) with XMP, so you gain headroom without moving to DDR5.
• Dual PCIe 4.0 x4 M.2: Both M.2 slots accept 2242, 2260, and 2280 drives, letting you run two fast SSDs side by side.
• Four SATA 6Gb/s Ports: Storage expands further with Intel Rapid Storage Technology supporting RAID 0/1/5/10 arrays.
• Realtek 1Gb Ethernet: A LANGuard-protected port delivers a steady wired connection for work and downloads.
• Realtek 7.1-Channel Audio: High-definition codec with audio shielding, premium capacitors, and dedicated PCB layers to cut interference.
• ASUS 5X PROTECTION III: DIGI+ VRM, Overvoltage Protection, SafeSlot Core, and stainless-steel back I/O reinforce board longevity.
• VRM Heatsink: A dedicated heatsink over the power stages holds voltage delivery steady under sustained load.
• Builder-Friendly Design: Q-DIMM and Q-Slot simplify memory and expansion card installation, while ProCool handles the power connector.
• Integrated Display Outputs: HDMI 2.1 supports 4K at 60Hz alongside a D-Sub port, active only with a CPU that has integrated graphics.
