Z790 Micro-ATX for Intel Core 12 13 14 Gen

The MSI Z790 MPOWER uses the Intel Z790 chipset on a Micro-ATX board. It accepts LGA 1700 processors from the 12th 13th and 14th generations plus Pentium Gold and Celeron models. Dual-channel DDR5 runs up to 7800 MHz overclocked with a 128 GB ceiling. Two PCIe x16 slots and one x1 slot provide expansion in a compact layout.

VRM heatsinks and fan headers manage thermals

Extended heatsinks cover the power delivery area to dissipate heat during sustained loads. Multiple fan headers allow targeted airflow across the VRM and M.2 zones. The 2.5 Gbps LAN and Realtek ALC897 7.1 audio operate within standard board power limits without adding noticeable acoustic load.

Rear I O includes USB 20Gbps Type C and 10Gbps ports

The back panel supplies one USB 20Gbps Type C three USB 10Gbps Type A four USB 2.0 plus 2.5 Gbps LAN and audio jacks. Front-panel headers add one USB 10Gbps Type C two USB 5Gbps Type A and four USB 2.0. Six SATA III and two M.2 interfaces leave flexibility for storage while the Micro-ATX form factor fits smaller chassis.

Questions about this item

How do I install the CPU into the LGA 1700 socket and what step is often missed?

Align the processor triangle with the socket marker, lower it gently, then secure the load lever; the step many skip is removing the protective cover only after the CPU is seated.

Which onboard component will need replacement first during long-term ownership?

The supplied CMOS battery powers the real-time clock and BIOS settings; it typically lasts several years before requiring a simple coin-cell swap.

What thermal limit appears first when the VRM runs under sustained heavy load?

The 16-phase power delivery is rated for high current, but prolonged maximum load will hit VRM temperature thresholds before any current limit is reached.
