This is a simple motherboard. That doesn’t mean it’s a bad motherboard, it means it does exactly what it’s advertised to do, every time, without any additional gadgets or changes that may get in the way of the motherboard working as advertised. As far as mini ITX gaming motherboards go, this one is definitely one of the most consistent on the market. 

If you want affordable and straightforward, as well as simple to install, this is a great motherboard. I’d suggest it to anyone who’s just working on their first build, or wants to have a board that they can put in and work on themselves. 

However, the I/O Shield is not pretty. I mean, it’s very not pretty. If you wanted to make it a little more aesthetically pleasing, a little bit of black marker or paint will definitely do the trick. The I/O shield is just not a good fit for most setups. It’s clunky and awkward in its color and design. If you don’t mind that, or are willing to do some changes, you’re completely able to have a very pleasing board. 

Pros

  • Straightforward
  • Affordable
  • Easy to install
  • Great “starter” motherboard for a computer build

Cons

  • I/O Shield is not necessarily attractive

This motherboard boots quickly, has great aesthetics, and provides you with crystal clear audio. It cools easily and well, and maintains its speed as it ages. This is the board I currently have on my own custom build. Just a word to the wise, however -- the RAM slot 2 died on this board for me after about 8 months of consistent use. This could be due to a technical flaw, but just be aware. 

Pros

  • Great cooling system
  • Durable
  • Incredibly fast
  • Great audio and graphics

Cons

  • RAM slot 2 died on my personal one, however, that may just be a motherboard specific to me scenario

Processors

Your processor, or your CPU, is your big gun. This is the set of instructions that basically use circuitry to run your entire motherboard. Investing in a quality CPU will make sure that your computer puts out the right logic, arithmetic, and control for years to come, allowing it to connect to every other functioning part of your computer. 

The big CPU recently has been Intel, especially 8th or 9th generation. This doesn’t mean Intel is the only one worth considering, it is just currently very versatile and popular. It’s a mid-to-high-end computer processor for consumers, workstations, and more, and replaced Pentium, which you may have heard of if you’re into more old school builds. 

Chipsets

A chipset is a group of electronic components that are in an integrated circuit known as the data management flow system. This integrated circuit will really prioritize what the motherboard will be good for. For instance, researching the chipset will give you a bit of background on what kind of processor that motherboard uses, or what it’s compatible with.

Memory

The bigger the number of gigabytes, the more memory your motherboard will have. Huge memories tend to run at higher price points, but they provide great services if you’re willing to prioritize that experience. 

Memory stores information for immediate use within the computer, meaning that memory will allow your computer to run faster and become more efficient. Memory is a top consideration, but that does also mean it’s a hot commodity. Investing in memory means investing in speed, but it also isn’t the only consideration. You can consider the memory speed of the motherboard as well, which will increase the capabilities of your build. 

Graphics

How will your motherboard translate the graphics from their source to your computer screen? That’s an important question and one that you can only answer by figuring out how your motherboard interprets graphics. Some of the most common graphics sources of motherboards are HDMI qualities, such as HDMI or HDMI 2.0, and both are worth your consideration when building a gaming computer. 

HDMI as an interface is very useful, however, it isn’t the end-all-be-all. There are also certain motherboards that may suggest you use GPUs, or require different types of audio and visual input. Paying attention to the graphics requirements of your motherboard is vital to the creation of a great home build. 

The Assembly of the Board

Pay attention to how your board is put together. For instance, sometimes boards don’t take into account the amount of effort that it may take to assemble them into the computer system. If this is the case, some of the essential functions may be blocked off by different connective wires inside of your build. In one recent circumstance, in one of my builds, the SATA port was in the way of my GPU, which ended up being more of an inconvenience than it was worth. 

By looking into the build and its quality, you will be able to head off any issues in the future, because the design of your motherboard will truly speak to its function.
