 Budget Micro ATX AMD AM4 Motherboards

1. Gigabyte GA-A320M-S2H – The Most Budget AM4 Motherboard

Gigabyte GA-A320M-S2H

One of the most, if not the most, affordable Micro ATX AM4 motherboard from a quality brand.

First up we have one of the most, if not the most, affordable and popular AMD AM4 motherboards out there.

If you came here looking to make a bee-line for the most inexpesive option, then this is hands down, the ideal option to go for.

While this is mostly intended for those looking for make an average PC for work or home related tasks, you can certainly use this for your gaming setup as well.

Being an affordable motherboard, it offers only the minimal specs. For instance unlike an average motherboard that has 4 x DIMM slots, this motherboard only has 2 x DIMM slots for RAM with a max support for 32 GB of DDR 4 RAM.

This is in all reality, more than enough for any economical build as well as for a full fledged gaming build.

One point to note is that despite being a micro ATX motherboard, it only offers a single PCIe X16 slot for graphics card. It DOES NOT offer any X4 slot that you can use for a Crossfire setup. This is due to the limitation of the A series chipset. The A series chipset maxes out with single PCIe x16 slot.

It does, however, offer 2 x PCIe X1 slot that you can use to install smaller add-in cards like a sound card or a WiFi card.

It should be noted that the A320 is the most basic chipset available for AMD motherboards. While affordable, they have limitations such as fewer SATA ports, fewer high speed USB ports and more importantly, for enthusiasts, they do not allow overclocking your CPU.

In short, if you want to make the most economical build, then this is the best budget AMD motherboard in the market.

2. Gigabyte A520M AORUS Elite – AM4 Gaming Motherboard Under $100

Choosing the Right Budget AM4 Motherboard

When choosing an AMD motherboards especially at a budget, you can keep the following points into account.

Chipset – The A Series is for Budget

One of the most important consideration when choosing an AM4 motherboard is the chipset.

AMD has three popular chipset  for desktop PC:

  • A Series: The most affordable series. Has minimal features.
  • B Series: Mid range series. Suitable for most gamers and intermediate power users.
  • X Series: For Enthusiasts. Suitable for gamers with a high budget and for professionals.

The following chart reveals the key differences between the different chipsets of the current series.

Form Factor Matters

Form factor pertains to size, slot configuration and price. Source: Reddit

When choosing the most economical option, the form factor of the motherboard matters a lot.

Form factor basically defines the size and dimension of the motherboard.

The most common motherboard form factors are ATX, Micro ATX and Mini ITX. ATX is the largest with a 12 x 9.6 inch dimension, micro ATX is smaller at 9.6 x 9.6 inch dimension and the Mini ITX is the smaller coming at 6.7 x 6.7 inch.

Generally, out of all these, the micro ATX motherboards are the cheapest to procure. Therefore, for utmost affordability go for micro ATX motherboard or mATX.

When it comes to the budget range Mini ITX motherboards are the most expensive. This is because these motherboard come with a built in WIFI and they do tend to charge a premium for their rare compact form factor.

The ATX motherboards have a vast price range. In the budget category, they are slightly more expensive than micro ATX motherboards, but can be found at a much cheaper price than Mini ITX motherboards.

Graphic Card Configuration and Expandability

Best Motherboards for SLI
The more graphics card you want to install the more PCIe X16 slots and lanes you need.

Motherboards vary heavily in terms of their PCIe configuration.

While all motherboards offer at least a single PCIe X16 slot so that you can add a graphics card to it, further expandability is usually costly.

For instance, motherboards that can handle NVIDIA SLI are fairly more expensive than an average motherboard since it has two X16 slots. NVIDIA requires at least an X8 slot to operate.

Hence when you populate the two X16 slots, they dial down their bandwidth to X8 each. This has to do with amount of PCIe lanes you have.

On the other hand, a motherboard designed for Crossfire is cheaper since AMD graphics card can run on an X4 slot. Therefore, if your motherboard has an extra X4 slot along with the primary X16 slot, you will be able to Crossfire.

Micro ATX and ATX motherboards usually have an additional X4 slot. Mini ITX, on the other hand, cap out at only a single PCIe X16 slot.

Hence, if you want more expandability in terms of more PCIe slots, the motherboard will cost extra.

Update Issues

It should be noted that the AM4 is fairly old socket and has been found on motherboards since the first generation AMD Ryzen processors came out.

Hence, you can still find older motherboards that were released years earlier that can technically harbor the newer AMD Ryzen processors.

Incidentally, the cheapest AM4 motherboard also happen to be the oldest. However, it should be noted that some of the older motherboards do not have their BIOS updated to support the newer gen processors.

Therefore their BIOS will need to be updated first.

Generally, if the stock for a certain motherboard is old, it will usually have an older BIOS and will need to be updated.

However, if the stock is newer then even if the model is old, there is a high chance that it will come factory updated to the latest BIOS that supports the newer AMD processors.

Final Words

We must reiterate again that the best budget AM4 motherboard for you depends upon what you want to accomplish. If you just need a simple motherboard that can harbor a single graphics card, then you can certainly find very cheap motherboards out there.

Special attention must be paid to the chipset and the form factor.
