MSI Pro Z690-A DDR4 Intel Motherboard

The MSI PRO Z690-A DDR4 is an ATX-form-factor motherboard built on the Intel Z690 chipset and designed for 12th Generation Intel Core, Pentium Gold, and Celeron processors in the LGA 1700 socket. Measuring 12 in. x 9.6 in. (30.5 cm x 24.4 cm) and featuring nine mounting holes, it fits standard ATX enclosures with ease. Memory support spans four DDR4 DIMM slots accommodating up to 128 GB of non-ECC unbuffered RAM. JEDEC-rated speeds begin at 2133 MHz and reach 3200 MHz natively; with XMP overclocking, a single-rank single-DIMM configuration can run at up to 5200+ MHz. The board runs dual-channel mode and supports Intel Extreme Memory Profile (XMP) for one-click frequency tuning. Expansion is handled by three PCIe x16 slots. The primary slot (PCI_E1), fed directly from the CPU, supports up to PCIe 5.0 x16 for the latest discrete graphics cards. Two additional slots from the Z690 chipset operate at PCIe 3.0 x4 and 3.0 x1 respectively, and a separate PCIe 3.0 x1 slot rounds out the layout. AMD CrossFire multi-GPU configurations are supported. Storage connectivity includes six SATA 6 Gb/s ports and four M.2 Key-M slots. M2_1 (CPU-connected) supports PCIe 4.0 x4 drives up to 22110 length; M2_2 and M2_4 (chipset) support PCIe 4.0 x4 and SATA; M2_3 (chipset) supports PCIe 3.0 x4 and SATA. M.2 Shield Frozr thermal covers help manage SSD temperatures. RAID 0, 1, 5, and 10 are available for SATA devices; RAID 0, 1, and 5 for NVMe. Power delivery uses a 14+1+1 Duet Rail VRM rated at 55 A per phase with DrMOS components, fed by two 8-pin ATX 12V connectors. The extended VRM heatsink and 7 W/mk MOSFET thermal pads assist sustained load performance. The PCB itself is a 6-layer, 2 oz copper server-grade design for added signal integrity and stability. Connectivity on the rear I/O includes a USB 3.2 Gen 2x2 20 Gbps Type-C port, a USB 3.2 Gen 2 10 Gbps Type-A port, two USB 3.2 Gen 1 5 Gbps Type-A ports, four USB 2.0 Type-A ports, and PS/2 keyboard/mouse. Display outputs comprise one HDMI 2.1 (4K 60 Hz with HDR) and one DisplayPort 1.4 (4K 60 Hz) for use with processors featuring integrated graphics. Networking is handled by an Intel I225-V 2.5 Gbps LAN controller. Audio uses a Realtek ALC897 codec delivering 7.1-channel high-definition output. A Flash BIOS Button enables firmware recovery without a CPU installed. RGB headers include one 4-pin RGB and two 3-pin RAINBOW (ARGB) connectors, complemented by four EZ Debug LEDs for quick fault diagnosis. Fan control covers one CPU fan header, one water-pump header, and six system fan headers, all 4-pin. Frozr AI Cooling automatically adjusts speeds based on CPU and GPU thermal readings. The board ships with a three-year warranty and supports Windows 11 64-bit and Windows 10 64-bit.
