Socket and CPU support

This Micro ATX motherboard uses the LGA 1700 socket and accepts 12th and 13th Gen Intel Core, Pentium Gold and Celeron processors. A dedicated LGA 1700 mounting bracket is required for cooler installation. The board ships with the Intel B660 chipset and supports Windows 11 out of the box.

Memory and expansion layout

Four 288-pin DDR4 slots run in dual channel up to 3200 and a maximum of 128 GB. One PCI Express 4.0 x16 slot and two PCI Express 3.0 x1 slots handle graphics and add-in cards. Storage options include four SATA 6 Gb/s ports and two M.2 sockets for NVME drives. Connectivity covers USB 3.2 Gen2 Type-C, HDMI 2.0, 2.5 GbE LAN and WiFi 6 802.11 ax.

Build fit and audience

The 6+2+1 phase hybrid power design with an 8-pin solid-pin CPU connector suits mid-range gaming or productivity builds that stay on air cooling. M.2 Thermal Guard and RGB Fusion 2.0 with addressable LED headers help with thermals and lighting. Q-Flash Plus allows BIOS updates without a CPU installed. Builders needing more than two M.2 slots, additional PCIe lanes or higher VRM phase counts should consider a full-size ATX alternative.
