The storage interface includes two M.2 slots and six SATA 6Gbps connectors that support RAID 0, 1, 5, and 10.

  • Overclock Button and Header

One notable feature specific to the Gigabyte Z370 Aorus Gaming 3 is its overclocking button.

In the 90s, some old motherboards had “Turbo” buttons on the PCB.

With that in mind, Gigabyte wanted to bring back the user-friendly, easy-access feature through the overclocking button on the rear panel.

Additionally, a synchronized header leads to the reset and power buttons on your front panel.

You can repurpose one of these front-panel buttons to double as the overclocking button.


  • Very affordable motherboard
  • Easy-to-understand board for gamers
  • Great fan control through the UEFI
  • OC header allows front panel OC repurposing
  • Dual BIOS for extra protection
  • Multiple integrated RGB LEDs increase onboard aesthetics

  • No Wi-Fi

3. Asus Prime Z370-A Motherboard 319

The Asus Prime Series reduces the difficulties of performance tuning to something that is much like a walk in the park.

Using intuitive software and firmware features, DIY PC builders can enjoy intelligent tuning options and comprehensive cooling solutions with an Asus Prime.

Asus offers the Prime Series with the Z370 chipset through the Prime Z370-A motherboard.


The Asus Prime Z370-A motherboard offers great value for PC builders looking for improved memory performance, SLI multi-graphics support, and more storage options.

Supporting SLI multi-GPU technology is the main advantage of the Prime Z370-A compared to other boards on the list, seeing as the ROG Maximus X Hero is more expensive.

Even today, it remains the best SLI-capable Z370 motherboard having a very affordable price tag.

Overall, the board has a pretty stylish look, carrying white and silver tones on its heatsinks and white decals on an otherwise all-black PCB.

  • Memory, Expansion, and Storage Options

Memory-wise, the Asus Prime Z370-A has a similar four-slot setup to the first two products we presented, supporting up to 64GB.

Maximum clocked memory speeds also sit at 4000MHz.

The three PCIe 3.0 x16 sockets are responsible for the SLI and 3-Way CrossFireX support, and four PCIe 3.0 x1 sockets are included for smaller expansion cards.

Storage options include two M.2 slots capable of running at x4 mode and six SATA 6Gbps ports.

If you can sacrifice the second M.2 slot to run only at x2 mode, you can use all three x16 PCIe 3.0 sockets simultaneously.


  • Low-cost board for allowing high-bandwidth SLI
  • Two M.2 slots and six SATA ports work simultaneously
  • Includes two USB 3.1 Gen2 ports
  • Superior memory bandwidth
  • Has a Thunderbolt 3 header

4. MSI Z370 Gaming Plus Motherboard 327

The MSI Z370 Gaming Plus motherboard is an entry-level option for 8th Gen Intel processors.

Wanting a budget-friendly system that still supports a multi-GPU setup gets easier with this motherboard.


The MSI Z370 Gaming Plus motherboard belongs to the lower end of the spectrum for value-oriented gaming boards.

It does not offer many features for overclocking and support SLI multi-GPU setups.

It also has smaller heatsinks than the other alternatives, and it minimizes RGB functionality to a single header.

A better alternative to the Gaming Plus is the Gaming Pro Carbon AC, but it also comes at a higher price point.

  • Memory, Expansion, and Storage Options

Maximum memory stock speeds for the MSI Z370 Gaming Plus can reach 2667MHz, typically higher than the stock speeds of the other choices.

However, if you overclock, the four DDR4 memory slots can reach data speeds up to 4000MHz.

The memory slots on this board also support up to 64GB of RAM.

Two PCIe 3.0 x16 sockets enable 2-Way AMD CrossFire multi-graphics, and four PCIe 3.0 x1 slots can accommodate smaller expansion cards.

Since it lacks a built-in PLX chip, the MSI Z370 Gaming Plus cannot support NVIDIA SLI technology.

Unfortunately, the MSI Z370 Gaming Plus only has a single M.2 slot, and using it with a SATA SSD disables the first of six SATA 6Gbps ports.


  • Great value for those on a budget
  • Exemplifies the dispensability of RGB lighting
  • Decent components across the board
  • Reliable audio codec
  • Supports 2-Way AMD CrossFire
  • Has the fastest stock RAM speed

5. ASRock Fatal1ty Z370 Gaming-ITX/ac Motherboard 285

All of the motherboards we’ve had so far come in the ATX form factor, and we’re ending these reviews with a slight deviation.

The ASRock Fatal1ty Z370 Gaming-ITX/ac uses the Mini-ITX form factor, which is smaller than the ATX.

Its smaller size allows setups using tighter spaces and smaller PC enclosures.


Even if it is such a small board, the ASRock Fatal1ty Z370 Gaming-ITX/ac broadens and balances the options for overclockers of mainstream CPUs.

Since a mini-ITX form factor reduces the available connectors on a board in many ways, we strongly suggest that you go for a panel with the slots or sockets you need.

  • Memory, Expansion, and Storage Options

Having a smaller form factor also means that the motherboard has fewer slots or sockets for various components.

The ASRock Fatal1ty Z370 Gaming-ITX/ac only has two DDR4 DIMM slots capable of holding up to 32GB RAM and overclocking around 4333MHz.

Even if it has the highest recorded RAM clock, your overclocking records will ultimately depend on your CPU.

The board also only has a single PCIe 3.0 x16 socket and a single M.2 slot to make way for six SATA 6Gbps ports.

  • Connectivity Features

Although the ASRock Fatal1ty Z370 Gaming-ITX/ac comes in a Mini-ITX build, it saves up some space for a Wi-Fi module.

In addition to the built-in Intel LAN adapter, it houses an Intel Dual Band Wireless-AC adapter capable of making connections through Wi-Fi or Bluetooth.

You can also expect top transfer speeds or high-resolution display outputs with the included Thunderbolt 3 header.


  • Small form factor allows smaller PC builds
  • Cheapest among the options
  • Excellent CPU overclocking capabilities
  • Includes a Thunderbolt 3 slot
  • With built-in Wi-Fi


  • Single M.2 slot
  • No multi-graphics support


In our opinion, the best Z370 motherboard doesn’t have to be very expensive since you’re only trying to spend a few more years with your 8th Gen processor.

Save up for the newer models in the future by getting the best value from a product at a lower price point.

With that said, we recommend the Gigabyte Z370 Aorus Gaming 3 motherboard as our best bet.

The Asus ROG Maximus X Hero is, no doubt, the best of all the options here, but it can be a waste of good money if you plan to upgrade to the newer CPUs soon.

The Gigabyte Aorus Z370 Gaming 3 lets you get the most out of your existing 8th Gen processor, and it doesn’t leave a big hole in your pocket.
