MSI Pro B660M-P DDR4 Intel Motherboard

The MSI Pro B660M-P DDR4 is a Micro-ATX motherboard built on the Intel B660 chipset and designed around the LGA 1700 socket, making it compatible with 12th Generation Intel Core, Pentium Gold, and Celeron processors including up to Core i9 class CPUs. It is a focused choice for professionals and prosumers seeking a stable, well-connected platform without unnecessary excess. Memory flexibility is a key strength. The board provides four DDR4 DIMM slots configured in a dual-channel arrangement and accepts a maximum of 128 GB of RAM. Out of the box it supports JEDEC-standard speeds of 2133, 2400, 2666, 2933, and 3200 MHz. For users who enable XMP profiles, frequencies can reach up to 4600 MHz (OC), with a wide ladder of intermediate speeds available including 3200, 3333, 3400, 3466, 3600, 3733, 3800, 4000, 4200, 4266, 4400, and 4600 MHz. Storage expandability covers common workloads. A single M.2 slot supports PCIe Gen 4 x4 (Lightning Gen4) NVMe drives for fast primary storage, backed by four SATA III ports for additional drives. RAID configurations 0, 1, 5, and 10 are supported across the SATA ports. Expansion slots include one PCIe x16 slot and two PCIe x1 slots. The PCIe x16 slot features MSI Steel Armor reinforcement to protect against GPU sag and electromagnetic interference. A reinforced slot helps heavier graphics cards remain seated securely over time. Connectivity is comprehensive. The rear panel provides one DisplayPort, one HDMI port, and one VGA output for systems with Intel integrated graphics. USB connectivity at the rear includes one USB 3.2 Gen 2 Type-C, one USB 3.2 Gen 1 Type-A, and four USB 2.0 ports. Front-panel headers add two USB 3.2 Gen 1 Type-A, one USB 3.2 Gen 1 Type-C, two USB 2.0 ports, and one serial port header. Networking is handled by a Realtek RTL8111H Gigabit LAN controller with MSI LAN Manager software for traffic prioritisation. Audio is managed by a Realtek ALC897 codec. A TPM header is present for hardware-based security requirements. The board ships with a 3-year manufacturer warranty and supports Windows 10 64-bit and Windows 11 64-bit.
