VRM Cooling: Features Stacked Fin Array, Direct-touch Cross Heat-pipe, Aluminum Backplate and Frozr AI software for improved thermal dissipation.

PCB Cooling: Premium 8-layer server-grade printed circuit design with 2 oz. thickened copper improves heat dissipation & reliability.

SSD Cooling: Double-sided M.2 Shield Frozr prevents thermal throttling and protects SSDs.

System Cooling: Connect and synchronize cooling with strategically placed pin-headers - including dual pump-fan headers.

Memory Boost: A fully-isolated DDR circuit delivers pure data signals for optimal gaming and overclocking performance.

XMP Profiles in MSI BIOS are MSI OC LAB optimized and can be easily enabled with auto power settings for optimized memory speed and stability.

*1DPC 1R Max. overclocking frequency 7800+ MHz, supports Intel XMP.

MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points to support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor also shields the point of contact from electromagnetic interference.

•  2 x PCI-e 5.0/4.0/3.0 x16 slots* (with Steel Armor**)
•  1 x PCI-e 4.0/3.0 x16 slot

*Supports x16/x0, x8/x8

**MSI Surface Mount Technology (SMT) solder welding improves signal clarity.

The MEG Z790 ACE MAX motherboard features MSI's latest M.2 slots:

•  1 x Gen5 x4 128Gbps slot (with double-sided M.2 Shield Frozr)
•  4 x Gen4 x4 64Gbps slots (with double-sided M.2 Shield Frozr)

Even the world’s fastest SSDs will automatically slow if thermal throttling firmware detects excessively high temperatures.

M.2 Shield Frozr is MSI's most advanced thermal solution, offering the best possible protection to ensure maximum SSD transfer speed performance.

Magnetic Tool-Free M.2 Design: This patented design enables true “wire-less” RGB function, while the screwless design provides the easiest way for M.2 installation.

EZ M.2 Clip: Install or replace M.2 SSD quickly and effortlessly without ever having to hunt for a screwdriver.

Dual 2.5G LAN: Dual Intel 2.5Gbps LAN controllers deliver a premium network gaming experience.

Dual Thunderbolt 4: Supports true 40Gbps transfer rates and 8K display support.

Wi-Fi 7: Features the latest Wi-Fi 7 solution (ultra-low latency, high-bandwidth) & Bluetooth 5.4 technology.

HD Audio: 7.1-Channel USB High Performance Audio with Audio Boost 5 HD & S/PDIF output.
