The motherboard has mostly a blackish color accent making it a perfect candidate for any color build. The stenciling is mostly in gray and black colors. There is a silver-colored Falcon stenciling on the chipset cover which looks good in an overall symphony of the design.

We have 4x DIMM slots for DDR4 RAM, 5x PCIe 3.0 slots at X16/X8/X4/X1, 6x SATA ports, Thunderbolt port, USB 2.0 ports, USB Type-C, USB 3.1 Gen 1, USB 3.2 ports, onboard audio solution driven by Realtek ALC1220-VB, Intel 2.5 GbE NIC, on-board WiFi 6 AX201 solution and nice handy I/O connectivity options. The PCB has an ATX form factor measuring 30.5cmX24.4cm and has support for Microsoft Windows 10 x64.

Let’s start with taking a look at the board from the top side.


The GIGABYTE Z490 AORUS PRO AX Gaming motherboard has an Intel LGA1200 socket. The socket is using Tantalum capacitors for better efficiency in handling transient loads.

There is a small arrow indicator on the socket’s cover indicating the corner to which the arrow marked side of the CPU has to be aligned. The Intel LGA1200 on The GIGABYTE Z490 AORUS PRO Review supports Intel 10th and the upcoming 11th generation of Core i series CPUs. The motherboard comes with an HDMI port supporting a maximum resolution of 4096×[email protected] Hz with a maximum shared memory of 512MB. The HDMI port is 1.4 version and HDCP 2.3.

GIGABYTE has gone all out on the VRM design and its cooling in the AORUS family which is similar to what we have seen in the Z390 series. All of their motherboards in this line pack almost similar VRM design and cooling and the Z490 AORUS PRO Review is no exception to that.

There are two black color coated aluminum heatsinks with multiple cut-outs to increase the surface area for effective heat dissipation. Fins-Array II uses a new louvered stacked-fins design which not only increases surface area by 300% compared to traditional heatsinks but also improves thermal efficiency with better airflow and heat exchange.

z490 a pro VRM design

Both heatsinks are connected using an 8mm heat pipe with a reduced gap between the assembly and the heat pipe. The GIGABYTE has used 1.5mm thick thermal pads rated for 5 W/mK thermal conductivity, between the important contact points on the PCB and the heatsinks thus ensuring there is no corner left unchecked when it comes to providing a powerful cooling solution for the MOSFETs.

GIGABYTE’s exclusive 2X Copper PCB design provides sufficient power trace paths between components to handle greater than normal power loads and to remove heat from the critical CPU power delivery area. This is essential to ensure that the motherboard is able to handle the increased power loading that is necessary when overclocking.

gigabyte z490 Copper

The 8+4 power connectors to power the CPU are located on the top left most side. The provision of extra 4-pins is for the Intel Core i9 10900 and 10850 variants which would require more power during overclocking. There is a 4-pin PWM hybrid Fan Header as well.

The GIGABYTE Z490 AORUS PRO Review features solid plated ATX 24pin & ATX 12V 8pin + 4pin power connectors to offer a stable power supply. This is advantageous as there is a larger contact area for the electricity with more metal quantity to sustain the higher power and heat.

gigabyte z490 ATX

There are 4 stainless steel reinforced DIMM slots on the GIGABYTE Z490 AORUS PRO AX Gaming motherboard. These are in the Dual Channel configuration. The maximum capacity is 128GB with 32GB per DIMM slot and the maximum supported frequency is 5000 MT/s (OC).

Z490 AORUS PRO Review supports ECC Un-buffered DIMM 1Rx8/2Rx8 memory modules (operate in non-ECC mode) as well non-ECC Un-buffered DIMM 1Rx8/2Rx8/1Rx16 memory modules. The good design aspect is that all memory routing is under the PCB inner layer shielded by a large ground layer to protect from external interference.

gigabyte z490 stainless steel

Since we are at it, there is a Realtek RT8120D for a single-phase PWM with a driver. For that, we have MOSFET configuration in the solution of 3 On Semiconductor 4C06N in a two-low one-high. We saw the same design on the Z390 AORUS PRO WIFI motherboard.

Let’s take a look at the top side’s connectivity provisions.

gigabyte z490 pro wifi

Starting from the right side, there is a 12V RGB header below which we have a digital RGB header. Each header has a clear label identifying which header is for what type of lighting.

Next, we have CPU_OPT and CPU_FAN headers. Another striking feature on the AORUS line of the motherboards is that every header is a hybrid one and utilizes PWM control. Each fan header is controlled by a nuvoTon 3947S PWM controller.

gigabyte z490 RGB header

We have a solid pin 24-pin ATX connector, a USB 3.2 Gen-1 header, and a USB 3.2 Gen-1 Type-C header.

gigabyte z490 24 pin

We have 3-pin and 5-pin thunderbolt Add-In headers. The Thunderbolt Add-In card is not included and needs to be purchased separately if needed.

There are 6x SATA ports rated at 6 Gbps located on the lower right side of the motherboard. This Z490 AORUS PRO Review supports RAID 0, RAID 1, RAID 5, and RAID 10.

thunderbolt RAID

We have 4 LED indicators for VGA, CPU, BOOT, DRAM marking printed at the bottom. This is the troubleshooting mechanism provided on this Z490 AORUS PRO motherboard. Each of these 4 LEDs is dedicated to the VGA, CPU, BOOT, and DRAM.

In case of any issue or error, the corresponding LED will lit up continuously until the problem is resolved. This is my complaint area. There is a thunderbolt header yet no debug LED! AORUS what’s up!

Let’s take a look at the connectivity options located at the base of the motherboard.

gigabyte z490 motherboard

Starting from the right side, we have a system panel connector. The base of the pins is color-coded for ease of identification and the corresponding configuration is labeled below the connector. Gigabyte has provided a G Connector which allows the user to easily connect the chassis front panel cables to this connector and then simply connect it to the front panel connector of the motherboard.

There is a 2-pin header right on the top of the system panel connector which is called Clear CMOS jumper. The user can use this header to reset the CMOS. In order to do that, power off your PC and touch both pins at a time using the tip of a screwdriver which will short the circuit. On the next boot cycle, the BIOS would be reset to its default settings.

On the left side of the front panel connector, there are 3x 4-pin hybrid fan headers. The rightmost header is for the pump.

gigabyte z490 motherboard 3 steps

There is a Q-Flash Plus button located after the fan headers. There is a dedicated USB port on the rear panel. The user can update the BIOS without using the CPU by simply downloading the BIOS file from the website. Rename it to Gigabyte.bin and copy it into the FAT32 formatted USB drive. Connect the drive to the designated USB port and press the Q-Flash button. Please note that you would still need to connect the 24-pin ATX and EPS connectors.

gigabyte z490 motherboard Q flash button

Next, we have two 9-pin USB 2.0 headers followed by a TPM header. Next, we have two lighting headers. The first one is +12V and the next one is +5V followed by the Demo LED and in the last, there is an HD Audio header to which the chassis’ front panel audio cable is connected which is optional though.

PCIe Slots

Gigabyte z490 USB Ports

GIGABYTE has mentioned that this Z490 AORUS PRO Review has PCIe 4.0 ready PCB and circuitry. They have implemented a PCIe 4.0 turbo b-clocker above the PCIe slots. This is what I have mentioned in the introduction that Comet Lake is not PCIe 4.0 ready but this socket will support the 11th gen chips which are expected to be using PCIe 4.0. T

his has left a little room for the vendors to implement PCIe 4.0 support on the Comet Lake platform. Much we are seeing a hybrid design otherwise there was only one choice out of two; either the motherboard supports PCIe 4.0 or not. This Z490 AORUS PRO motherboard has a total of 5x PCIe slots.

The top slot is electrically wired to the CPU socket. PCIe slots have higher slot signal stability and lower impedance, maximizing PCIe bandwidth. Here is the configuration information of these slots:

  • 1 x PCI Express x16 slot, running at x16 (PCIEX16) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  • 1 x PCI Express x16 slot, running at x8 (PCIEX8) The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot operates at up to x8 mode.
  • 1 x PCI Express x16 slot, running at x4 (PCIEX4)
  • 2 x PCI Express x1 slots

SLI/CF Support

  • Support for NVIDIA® Quad-GPU SLI™ and 2-Way NVIDIA® SLI™ technologies

Overclocking, Power Consumption, and Thermals

For the purpose of to the point testing, we disabled the Gigabyte Core enhancement to stay with the Intel default’s. On stock, all the settings were left at Auto except the DRAM voltage and timings. We have used Blender Benchmark on stock and overclocked settings for the thermals and stability. CORSAIR Link software was used to take a reading of the power consumption.

The above picture shows what it is like to have Intel i7 10700k on the Auto, Stock settings. Two cores have hit the 5.1GHz mark which is exactly the Turbo Boost Max Tech 3.0. The average temperature was 65.75°C with an ambient of 19.5°C. The maximum power package was 134.475W.

The above picture shows the power draw of the system as reported by CORSAIR iCUE coming off their AX1200i PSU. Please, note that the graphics card was not under any load. Your mileage would vary and there is no way this should be taken as a reference point.

I was able to overclock the chip with all cores on 5.1GHz using 1.379V. For this, I have to set the Voltage Control Mode in Normal and use the override method with -0.100 offset. The LLC was set to Auto. Under Blender Benchmark the average temperature was 72.25°C at an ambient of 18.5°C. The maximum power on the package was 172.339W. The system power draw was around 332W without the graphics load.

Here is the Cinebench R23 result from the overclocking

Thermal Imaging

We have used the Hti HT18 Thermal camera to record the thermals of the VRM area of the motherboard under load using blender benchmark on the stock and with overclock scenario.

With 5.1GHz all core under Blender Benchmark testing, the maximum temperature on the MOSFETs was 62.4°C with an ambient of 18.5°C.

This goes to show the powerful cooling solution employed by the AORUS on their Z490 PRO AX motherboard. I am expecting these values to be high with Intel i9 and more aggressive overclock but given the result, these VRMs have enough cooling to handle any load.


We are seeing another refresh of Skylake from Intel using a 14nm fab node. AMD with their Zen 3 has broken the inertia and took over a substantial lead which in the end is a win-win for the consumers. The Comet Lake from Intel is their 10th gen Core i series CPUs using the revamped socket using 1200 pins to address the power requirements of their Core i9 CPUs in the lineup. With this new socket, Intel has released new chipsets to go hand-in-hand.

Z490 is their enthusiast segment chipset with loads of features and overclocking potentials though there are meager differences between the Z490 and the Z390 chipsets with Intel focusing on networking more than any other improvement as we have 2.5 GbE connectivity and WiFi 6 with AX and Bluetooth 5.1 connectivity.

Another difference is the DRAM frequency transfer of 2999MHz as compared to the 2666 MHz. Comet Lake comes with 40 PCIe lanes with 16 from the CPU socket and 24 from the chipset. I digress as this article is about the motherboard not the overview of the chipset itself.

The GIGABYTE Z490 AORUS PRO AX Gaming Motherboard is more of an upper mid-range offering from the manufacturer with balanced features which now makes more sense with reduced pricing of $219.99 as compared to $259.99 which was kinda premium price tag. Coming from the APRUS family, one is sure that this Z490 AORUS PRO Review packs beefy power delivery in the form of 12+1 power phases with DrMOS using doublers and powerful cooling provision for the VRM/MOSFET.

GIGABYTE is using an Intersil ISL69269 PWM controller with SiC620A doublers to deliver clean power to the CPU socket which is using an array of Tantalum Polymer capacitors for efficient transient load and stability.

Using the Intel LGA1200 socket and Z490 chipset this motherboard is supporting the Intel 10th gen CPUs and will be compatible with their 11th gen CPUs on the horizon.

Unfortunately, the Comet Lake does not support PCIe 4.0 protocol which is a letdown particularly when AMD with its Zen2+ already had PCIe 4.0 hardware in the market when this generation was launched. With Zen 3, AMD has taken their game to the next level which is unrivaled at the moment. This is history in making!

The GIGABYTE Z490 AORUS PRO AX Gaming Motherboard has 4 DIMM slots with a maximum capacity of 128GB DDR4 in a dual-channel using a maximum supported transfer rate of 5000 MT/s. These slots are stainless steel reinforced with PCB having a shielded layout to avoid interference.

The board has dual M.2 ports with thermal guards to ensure that the M.2 drives don’t get throttle under load and provide maximum performance. GIGABYTE has taken a hybrid approach as they have provided a PCIe 4.0 ready PCB with PCIe 4.0 Turbo B-Clock chip to provide future compatibility. We have 5x PCIe slots with the top two slots being PCIe 4.0 ready.

The PCIe X16/X8 slots are stainless steel reinforced. There are 6x SATA3 ports which share bandwidth with the M.2 ports and PCIe 3.0 X4 slot.

The beefy VRM/MOSFET cooling is coming from two aluminum louvered stacked fins (Fins Array-II) and jointed by an 8mm heat pipe using Direct-Touch II technology. The complete solution is placed on the VRM/MOSFET using 1.5mm (5W/mK) thick thermal pads to ensure effective heat dissipation. In terms of the cooling department, there are 8x hybrid 4-pin fan/pump headers.

There are 7x thermal sensors across the entire PCB and 2 external sensors are provided. Smart Fan 5 is used to control the functionality of these headers. The motherboard has 8+4 pin EPS connectors using a solid pin design. The board hosts plenty of USB ports including 5x USB 3.2 Gen-1 ports, 2x USB 3.2 Gen-2 Type-A, and 2x USB Type-C ports. The motherboard has 2 RGB LED zones on the shroud area and the Audio PCB layer. In addition, there are 2x 5V lighting headers and 2x 12V lighting headers.


The motherboard comes with Intel 2.5 GbE NIC and a 2×2 WiFi 6 201AX solution with an antenna. The Audio section is using Chemicon capacitors to drive the Realtek ALC1220 with VB series Audio Controller. The motherboard comes with a single 256 Mbit flash UEFI/BIOS.

When it comes to the performance and actual numbers, this Z490 AORUS PRO motherboard is crunching on the numbers in this price range. I am not expecting much on this VRM/MOSFET set but they can handle the given load at ease depending upon the CPU used and the overclocking employed.

If you are into serious overclocking, then look up the Master and XTREME motherboards from AORUS as they pack very beefy VRM solution capable of handling up to 90A per phase. The beefy cooling solution on the VRM is paying off as the maximum temperature on the VRM was 62.4°C and with a bit of tweaking the voltage setting without disturbing the LLCs, we were able to run our 10700k hit 5.1GHz all core at 1.379V VCORE.

The 240mm AIO solution from EK Water Block has no issue handling this overclock even with AVX load. But all efforts to make 5.2GHz happened on all core was futile as the chip easily reached thermal limits and throttled. 1.5V seems to be required to achieve the 5.2GHz. I never had a stable 5.2GHz stable overclock but 5.1GHz was like a walk in the park. The audio solution is working to its name and wireless internet connectivity was super smooth.
