Its rear I/O plate has a heatsink that conceals a 6mm heat pipe. The latter is necessary for diverting heat away from the CPU. 

The Z790 AORUS ELITE AX uses the same LGA1700 socket as the Intel 12th-generation platform. It enables cross-generation compatibility between the 12th and 13th-generation platforms. 

Additionally, coolers that are compatible with the Intel LGA1700 will also work with the platform.

Cooling-wise, the company implemented an ideal solution by including a big heatsink that covers the power delivery circuit. The cover features built-in moulding heatsinks to enhance heat transfers with optimised airflow. 

Both heatsinks link via 6mm thick copper heat pipes and have thermal pads rated up to 7.5W/mK.

The motherboard features adequate digital power phases: 16 phases in parallel for the VCore. It utilises the Infineon TDA-21472 SPS 70A to make it 1120A. 

It has a GT MOSFET using a 5×5 footprint 60A to deliver stable power to the iGPU. Then, there are two MOSFETs with a max of 120A to provide adequate power to the PCIe lanes. The board seems enough in power delivery, but the twin digital phases seem like a doubler design.

Lastly, two 8-pin EPS connectors are available for a smooth and seamless power supply. 

The Z790 AORUS ELITE AX has four DDR5-based DIMM slots. Remember that these do not have SMD stainless steel and anti-plate bending support.

The DDR5 supports up to 7600MHz, but make sure that the BIOS is updated. By default, the motherboard works with 4400 and 4800MHz. Plus, it supports 128GB RAM capacity with one stick density of 32GB.

Its dual-architecture works with and can handle un-buffered DIMM 1Rx8 / 2Rx8 / 1Rx16 memory modules. And additionally, these support AMD EXPO and XMP. 

For the motherboard to support DDR5 Auto Booster to 5000MHz, a one-click operation is necessary on the UEFI/BIOS. You can create and define your SPD profile in XMP 3.0 and native memory modules. 

You can save and load one user-defined profile either locally or to/from an external storage device. Doing this will let you load the saved profile to another system and have that system set up immediately. 

Moreover, the board supports fast memory performance simulation according to timing parameters and user input clock. 

Like the AMD Zen 4, Intel included M.2 Gen 5 support on its 13th-generation platform. But the thing is, only those high-end Z790 Gigabyte models offer this type of support. 

But on this motherboard, it has four M.2 ports. And although these support the 221100 form factor, these are not Gen 5. All the ports are PCIe Gen 4, and only the top slot has wiring with the CPU socket. The remaining three are all wired to the chipset. 

Each of the M.2 ports has the EZ-Latch Plus. 

When it comes to PCIe slots, this motherboard has three of them.

The top PCIe slot is wired to the CPU socket and is a fully-functional PCIe Gen 5 x16 slot. It has a theoretical bandwidth of 128GB/s and has SMD stainless steel reinforced. This type of steel is an ultra-durable PCIe armour stainless steel with high tensile strength. 

Like previous GIGABYTE motherboards, the product employs a double locking bracket for the uppermost slot. The company even offered an extended PCIe locker at the top of the standard locker called EZ-Latch. 

This feature is convenient for removing the graphics card from its slot. And since the extended locker reaches the top NVMe slot, it becomes easier to access despite being a space-constrained spot.

You will find non-stainless steel PCIe slots, which are PCIe Gen 4 types. There are two of these, and both have ratings of x4 speed. 

The audio solution on this motherboard is adequate and runs using the Realtek ALC897 codec.

WIMA and Fine Gold capacitors power the audio, ensuring a studio-quality experience. There is also a line-out and mic-in on the back IO. Plus, there is a S/PDIF to get plenty of options for speaker setups or surround sound systems. AORUS motherboards feature an audio noise guard, which isolates sensitive analogue audio components from potential PCB noise pollution.

The Z790 AORUS ELITE AX uses a single 2.5GbE LAN chip that uses Realtek RTL8125BG. It has one RJ-45 port on the rear panel for wired network connection to support 10/100/1000/2500Mbps. This LAN chip offers twice the speed of 1GbE.

Gigabyte implemented the Intel WiFi module on the mSATA NGGF port, which you can find on the rear IO panel. 

The Intel AX211 chip, which supports WiFi 6E connectivity, is the main driving force. The latest 802.11ax WiFi 6E wireless solution with a new dedicated 6GHz band enables gigabit wireless performance. Thus, providing smooth video streaming, a better gaming experience, fewer dropped connections and speeds up to 2.4Gbps. 

Additionally, the motherboard supports the Bluetooth 5.3 protocol, which offers an extended range compared to Bluetooth 5.2. It also provides faster transmission speed.

Z790 AORUS ELITE AX Motherboard USB Connectors

When it comes to high-speed USBs, the rear IO has a variety of choices. A Type-C format USB 3.2 Gen2x2 rated up to 20GB/s is your fastest USB port. Networking is also excellent, with high-speed 2.5 Gigabit LAN and onboard WiFi 6E.
