MSI MPG Z790 Carbon WiFi
Stealthy Carbon Fiber Aesthetics Powered by a Massive 19-Phase 105A Direct Power Delivery System
Overview
How It Works
Power Conversion and Regulation
Dual 8-pin CPU power connectors feed current into the 19+1+1 direct VRM, where 105A SPS MOSFETs drop the 12V supply to sub-1.4V CPU core voltages with minimal electrical ripple.
High-Frequency DDR5 Signal Isolation
The Memory Boost technology utilizes isolated signal trace layouts embedded within an 8-layer server-grade PCB to shield high-speed memory signals from electromagnetic interference.
PCIe 5.0 & NVMe Data Multiplexing
High-speed differential lines route PCIe 5.0 lanes directly from the CPU socket to the primary x16 graphics slot and top M.2 slot, supporting up to 128 GB/s bandwidth.
Thermal Heat Transfer & Dissipation
An extended heavy-duty heatsink connected by a direct-touch heatpipe absorbs thermal energy from the VRMs and transfers it efficiently across dense aluminum fin arrays.

Setup Tips
Enable XMP in BIOS
After installing your memory modules into DIMM slots A2 and B2, enter the UEFI BIOS and toggle Intel XMP 3.0 Profile 1 to run your RAM at its rated high speeds.
Update BIOS before installing 14th Gen CPUs
Format a USB drive to FAT32, copy the latest BIOS file renamed to `MSI.ROM`, insert it into the dedicated Flash BIOS USB port, and press the Flash BIOS button for tool-free firmware flashing.
Install Wi-Fi Antenna for Bluetooth & Wireless Connectivity
Ensure the included gold-plated Wi-Fi antenna base is securely screwed into the rear I/O connectors to enable optimal Wi-Fi 6E and Bluetooth 5.3 range.
Optimal M.2 Drive Placement
To prevent splitting CPU PCIe lanes on your primary GPU slot, install your main operating system NVMe drive into M.2_2 or M.2_3 (PCIe 4.0 slots) unless you explicitly require Gen5 SSD bandwidth.
Connect Front Panel USB 3.2 Gen 2x2 Header
Plug your case's internal Type-C cable into the board's high-speed USB 3.2 Gen 2x2 front panel header to unlock 20Gbps transfers on front panel chassis ports.
