GIGABYTE GA-A320M-S2H

One of the most affordable micro ATX motherboard for AMD builds out there. For Ryzen 1, 2, 3.

There re budget motherboards, and then there is this. If you are looking to build the most affordable PC with an AMD processor then we highly recommend. It features an AM4 socket and therefore can work with the latest AMD Ryzen processors.

One caveat here is that you may need to update the BIOS in order to use it for the latest Ryzen Gen 3 processors IF the motherboard does not come factory updated.

Now this is as affordable as it can get. If you are trying to save each and every dime while still maintaining the quality of a respectable brand name, then this is a great option .

Of course, you must realize that this is a bear minimum product. It only offers a single PCIe X16 expansion slot for a single graphics card, only two DIMM RAM slots for 32 GB of RAM and a single M.2 slot for NVME or SATA SSD. On top of that since this is based on the A320 chipset, it does NOT support overclocking.

It does offer 2 x PCIe X1 slot for adding smaller cards such as WiFi but you would not be able to add an extra graphics card on to it.

As such, when buying this motherboard, you must pay special attention to the fact that this motherboard is not built for high performance. It is instead built for simple home and office users.

Hence, whether you are building a PC for your small home office or for simple personal use, you can use this motherboard as the building block for your AMD PC.

Sale
Asus Prime H310M-E R2.0

Among the cheapest Intel LGA 1151 based motherboards. For 8th and 9th gen Intel Processors.

Much like the previous motherboard, this is also an affordable option, however, this motherboard features the LGA1151 socket that is suitable for the 8th and 9th gen Intel processors from Core, Pentium and Celeron series.

Like the motherboard above, this is a bear minimum product suitable for basic users. So if you are building a PC for home use, office or even for casual gaming, then this motherboard can come in handy.

This may come particularly handy in instance if you have a very limited budget and you want to maximize your gaming budget on the graphics card. In that case, this motherboard may help you achieve your goal.

As far as the expansion capability goes, this motherboard only has a single PCIe X1 slot and therefore can only handle a single graphics card at a time on a full X16 bandwidth.

However, this motherboard does have a few tricks up its sleeve that makes it better than the previous motherboard.

For starters, this can support a higher amount of RAM thanks to 4 x DIMM slots. Furthermore, it also features the large PCIe X4 slot which you can use for expansion cards that require a higher bandwidth such as SSD expansion card or RAID controllers.

Finally, while the previous motherboard only features 4 x SATA 3 slots, this has 6 SATA 3 slots giving you more hard disk expansion capability.

All in all, if you are looking to build an affordable Intel build, then this is the best budget micro ATX motherboard.

3. ASUS Prime B460M – LGA 1200 – For the 10th Gen Intel Processors

ASUS Prime B460M

Affordable Micro ATX board for LGA 1200 builds. For 10th gen Intel Processors.

Next up we have a basic and a budget motherboard with the Intel LGA1200 socket. This is the socket used by the latest 10th gen Intel processors.

Therefore, if you are planning on building an inexpensive PC whether for work or for gaming with the latest 10th Gen Intel processors, this motherboard will enable you to save up on cost.

It should be noted that while it is a cheap LGA1200 motherboard, it is more expensive than the two motherboard we reviewed above. Since it features the latest socket, it does tend to cost a bit higher than motherboards with older sockets.

The good news however is that it has a newer chipset, it offers better VRM heatsink, a larger number of VRMs as well as LED lights for the enthusiasts out there.

When it comes to expansion, it offers a single PCIe X16 slot like most budget mATX motherboards out there. Along with that it also offers 2 x PCIE X1 slots.

One lucrative feature this motherboard offers is that it has 2 x M.2 expansion slot instead of just one as is common on most budget motherboards. Both can support NVME SSDs.

As far as the RAM expansion goes, this can support upto 128 GB. It is highly unlikely that you would ever come even close to this in the near future for your budget build.

So in short, if you want to build a budget setup with the latest 10th gen Intel processors, then this is the best budget micro ATX motherboard in our opinion.

4. ASUS Prime B550M-A – New AMD Chipset B550 with PCIe v4

ASUS Prime B550M-A

AMD AM4 motherboard with the latest B550 chipset. Factory BIOS updated for Ryzen 3, PCIe v4, WiFi 6.

This is slightly more expensive than the rest mentioned here, but if you are looking to build an AMD system that is future proof and has support for the latest Ryzen processors from the get go, then this is the motherboard we recommend.

For starters, this motherboard offers the latest B550 chipset with the AM4 socket. The great thing about this chipset is that it does not require a BIOS update in order to use the Ryzen Gen 3 processors.

In motherboards with older chipsets such as B450, you may be required to update the BIOS if you want to use the latest Gen 3 processors.

On top of that, this chipset conforms to the latest PCIe 4.0 protocol making it very future proof. It also has support for WiFi 6, has better heat sinks and a better phase power design making it great for casual gamers and heavy users.

As far as the expansion capability goes, it is minimal. It offers a single PCIe X16 slot for the graphics card and 2 x PCIE X1 slot for smaller cards. It also does not do extraordinarily on the SATA port department as it only offers the average of 4 SATA 3 ports.

One upside here is that it does offer 2 x M.2 slots with support for NVME SSD on each.

In short, if you are going for the latest AMD build, then this is the best budget micro ATX motherboard we can recommend.

5. ASUS TUF Gaming B550M – Budget Gaming Motherboard with mATX form Factor

Sale
ASUS TUF Gaming B550M

Affordable gaming grade micro ATX motherboard with B550 AMD chipset and PCIe v4.0.

Finally we have a micro ATX motherboard that is more or less catered towards the enthusiasts as compared to average users.

Naturally this is the most expensive motherboard in this list since the primary audience of this motherboard are gamers and heavy users.

This is an AMD AM4 motherboard with the latest B550 chipset suitable for the latest Ryzen processors. It offers the latest PCIe 4.0 protocol, WiFi 6 protocol, faster USB ports and a better phase power design compared to basic motherboards.

As such, if you want to overclock, you would be able to do so thanks to its excellent VRM design and larger heat sinks.

Unlike the previous motherboards mentioned here, this motherboard offers 2x PCIE X16 slots. One of these slots works at X4 bandwidth and the other works at full X16 bandwidth.

Hence, if you ever choose to build an AMD Crossfire setup with dual graphics card, you would be able to do so with this. This is because AMD Crossfire can work with only X4 bandwidth.

The way this would work is that if you have only a single graphics card, you must install it in the first PCIe X16 slot that has the full X16 bandwidth.

When you choose to install a second graphics card, install it in the second X16 slot with the X4 bandwidth.

So in short, if you are gamer looking to build an affordable AMD rig, then this is the best budget micro ATX motherboard in our opinion.
