Z690 platform for 12th Gen Intel Core

The MSI MEG Z690 ACE is an Intel Z690 motherboard built for the LGA 1700 socket. It supports 12th Gen Intel Core, Pentium Gold and Celeron processors in an E-ATX layout. Dual-channel DDR5 memory runs up to 6666 MHz with a 128 GB maximum capacity. The board targets enthusiasts building high-end desktop systems.

PCIe 5.0 x16 slot and dual 2.5 Gbps LAN

The primary PCIe x16 slot runs at PCIe 5.0 x16 directly from the CPU, replacing older PCIe 4.0 links for graphics and high-speed add-in cards. Two additional x16 slots operate at x8 and x4, while a chipset-driven slot provides PCIe 4.0 x4. Two Intel I225V controllers deliver dual 2.5 Gbps Ethernet, upgrading from single 1 Gbps connections on typical mainstream boards.

20 Gbps USB Type-C and 7.1 audio with ESS DAC

Front-panel I/O includes two USB 3.2 Gen 2x2 20 Gbps Type-C connectors, while the rear panel supplies one Type-C and three Type-A ports at 10 Gbps. Six SATA III ports and five M.2 interfaces handle storage expansion. Audio uses a Realtek ALC4082 codec paired with an ESS SABRE9018Q2C DAC for 7.1-channel output and S/PDIF. The package includes the motherboard, CMOS battery, one SATA cable, an I/O shield and a Wi-Fi antenna.

Questions about this item

What case clearance does the E-ATX board and its 128GB DDR5 capacity require?

The board follows the E-ATX form factor, so the chassis must accept that larger footprint; four DDR5 slots support up to 128GB total.

Which mounting step is most often missed when fitting the LGA 1700 socket and Z690 chipset?

Install the CPU into the LGA 1700 socket, secure the retention lever, then apply thermal paste and attach the cooler before powering on.

When will the CMOS battery and SATA cable included in the box need replacement?

Replace the CMOS battery when the system loses time or BIOS settings; swap the SATA cable if drive errors or connection issues appear.
