Z390 AORUS Master Motherboard Review

Intel is on a big change in their mainstream processor platform, from generational core clock bump it is now turned into a generational core count bump while keeping improvements in the clock speed. Intel now has unleashing their first mainstream 8 core processor with their new 9th Generation lineup, as the Coffee Lake Refresh. We have the famous Core i7 SKU with 8 cores 8 threads and the new Core i9 SKU with 8 cores 16 threads.

With new processor platform, Intel also released a new Z390 chipset and all motherboard manufacturers are ready with products ranging from budget to mainstream and with designs and features, aimed at general gamers to extreme overclockers. Today we are reviewing our first Z390 motherboard the Z390 AORUS Master Motherboard from GIGABYTE, which is their top of the line Z390 motherboard with 12 Phases IR Digital VRM, Fins-Array Heatsink, RGB Fusion, 802.11ac Wireless, Triple M.2 with Thermal Guards, ESS SABRE HIFI 9118, Intel® GbE LAN with cFosSpeed, Front & Rear USB 3.1 Gen 2 Type-C and more.

Now let's see what this new Intel Z390 chipset based gaming board have for us.


Motherboard comes in a mate gray and orange colour finishing box with a big AORUS logo with motherboard model no. in front. At the rear of the box, we find that GIGABYTE goes into great detail on highlighting the specifications and features of the motherboard.

Inside the box


Board is a solid build on a black PCB with all new pre-installed back I/O Cover and the heatsinks are solid aluminum with copper heat-pipe and fins-array. All NVMe PCIe slots have nice machined aluminum heatsink which improving overall appearance and gives board a solid feel.

Using AORUS EasyTune software and with single click we were able to OC Intel i7-9700K up 5.1GHz.

Using Corsair H115i Platinum RGB Cooler we were able to OC Intel i7-9700K up 5.2GHz stable with memory at 3600MHz.

Extreme Overclocking

To perform some extreme Overclocking we used Phase changer Cooler and cooled the CPU up to -32C.

Power Consumption

Wattage reading as per displayed by APC Pro 1000VA (Model no. BR1000G-IN) UPS.


  • Nice Look
  • Good VRM power and cooling implementation
  • High Quality Audio

  • Lot of RGB LED ports with support for either 5v or 12v Addressable LED lighting strips
  • Front USB 3.0 header with USB TurboCharger support
  • Triple M.2 ports with heatsink


  • Power consumption a bit high (Consider this being the issue with Intel 9th Generation lineup )


AORUS Z390 Master is a premium motherboard from GIGABYTE offering one of the best VRM power and cooling implementation in Z390 motherboards. Perfect for getting best out of the Intel's new 9th Generation processor lineup. Elegant design and lot of RGB support with solid layout, M.2 and high quality audio solution offered by AORUS Z390 Mastermotherboard are all obvious plus points, but we find the overclocking capability of the board the most. Using AORUS EasyTune software and with single click we were able to OC Intel i7-9700K up 5.1GHz and with Phase changer Cooler and by cooling the CPU up to -32C we were able to push i7-9700K upto 5.8GHz.

At the conclusion we found Z390 AORUS Master motherboard as the best motherboard for users going for Intel's new 9th Generation build and worthy of our PC TeK Reviews EXCELLENCE Award.
