Buying Guide For The Best Micro ATX Motherboards

If you are on a budget but still want a decent computer, then going with a micro ATX motherboard can be a great pick. Even though they are quite cheaper than standard ATX motherboards, you get most of the functionality of a full-size ATX motherboard. Such motherboards can also be viable if you simply want to make a compact computer.

You can get one of the best micro ATX motherboards present here in this article. To help you out in picking up the right one, all of them have been mentioned, along with their major features and options. And now, we are here with a detailed buying guide for the best micro ATX motherboards so that you can get the right one after following these factors one by one:

1. Socket and Chipset

The first and most important thing to check before getting a micro ATX motherboard is its socket and chipset. These essentially tell you about the processor that you can use with a given motherboard. As for the micro ATX motherboards present in this article, all of them use the AM4 CPU socket.

This socket is combined along with the decently powerful and feature-rich B450 motherboard chipset. Thanks to this, you can use almost any AMD Ryzen CPU ranging from the 1000 series to the brand new 5000 series with a BIOS update. Although, with these mid-tier motherboards, it is not recommended to use a high-end processor for obvious budget and power delivery restrictions.

2. PCIE Slots

Since AMD Ryzen CPUs do not have an internal graphics card, you are surely going to install a dedicated one on your computer. There are also other things like sound cards and network cards that can be installed on your computer’s motherboard.

All of these things are installed in the PCIE slots offered by the motherboard, which makes them quite important. Most micro ATX motherboards will offer two full-size PCIE slots along with a small one, which should be quite decent in most cases.

3. Memory Support

Even if you have a powerful CPU, you cannot get the most out of it unless you have enough memory on your computer. Hence, checking the memory support offered by your computer is quite important.

You will find micro ATX motherboard models with either 2 or 4 memory slots where having more slots is always better. Other than this, you should also check the maximum memory capacity of your micro ATX motherboard. Similarly, the maximum memory speed supported is also quite important to check.

4. Storage Support

You should also check the storage options offered by your micro ATX motherboard to ensure that you have enough storage speeds along with high storage speeds. For bulk storage and moderate speeds, you are either going to use an HDD or a SATA SSD.

Thus, almost all motherboards come with 4 or 6 SATA slots, where having more slots is always better. Modern micro ATX motherboards also offer either 1 or 2 NVME slots, which can be used to install much faster NVME SSD for excellent storage access speeds.

5. Ports

Apart from connecting all of the internal components of your computer, the motherboard is also used to connect external devices like peripherals and storage devices. All of these are connected to the rear ports offered by your motherboard. While choosing the right motherboard, you should go with the one that offers multiple high-speed ports.

Apart from basic audio ports, PS/2 port, USB 2.0 ports, VGA port, DVI-D port, ethernet port, you should also look out for high-speed USB 3.0 ports, USB Type C port, HDMI port, and others. Any motherboard that offers multiple high-speed ports is going to be highly practical and handy in the long run.

6. Warranty

The motherboard of your computer is one of the most important components of your computer. Thus, if you want your computer to keep working without any issues, then your computer’s motherboard should also last for a long time. Thankfully, almost all motherboards come with a 3-year long warranty for peace of mind as it should be more than enough for most buyers.
