Finding SLI support on an AMD motherboard is difficult at a budget price range. This motherboard, despite being the most expensive in this list, is the cheapest motherboard that offers SLI support.

The reason for the higher price tag is simple. Firstly, AMD encoruages you to couple their motherboard with an AMD GPU. Secondly, unlike an AMD GPU that requires a minimum of X4 PCIe slot to operate, NVIDIA GPU, on the other hand, requires a minimum of X8 PCIe slot to operate.

In other words, to support SLI you will need at least two PCIe X8 slots. This configuraiton is generally more expensive. Hence the higher price tag.

Besides that, noone can argue the quality this motherboard provides. Other than the high quality components that are fit for overclocking, this offers gaming hotkey and myriad of special features specially catered toward gamers.

What to Expect Here?

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

Cheaper Than Intel Counterparts

For starters it is worth noting that a typical AMD motherboard is much cheaper than an Intel motherboard.

Therefore, for the ultimate economical build, AMD is the way to go.

However, it is also worth noting that an average AMD processor is weaker than an average Intel processor.

Yet for basic work as well as for gaming, AMD is still well worth it. Take for example the 5th generation gaming console. They all use AMD based systems.

Form Factor Matters

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.

The current AMD Ryzen generation is the third. However, you can still find older motherboards that were released years earlier.

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.

Therefore, while they can technically support the newer generation of AMD Ryzen processors, 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 if you get a newer generation Ryzen processor.

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.

In this article the best budget AMD motherboard we have selected do not have any reported BIOS update issue from their customers.

Final Words

In this article we reviewed some of the best budget AM4 motherboards from various form factors.

We must reiterate again that the right 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.

However, if you plan to have multiple graphics card or if you plan to overclock, then you will need to dish out a little extra.
