Best Amd Motherboards Under 100 – BUYER’S GUIDE
If you are working with a tight budget, you can definitely choose a less-expensive motherboard. And, if all you are planning on doing is building a single video card setup then you don’t necessarily have to spend hundreds of dollars on an extreme motherboard.
Ultimately, though, your motherboard is an important part of your computer and you should definitely take the time to choose one that will serve your needs and even will give you upgrade options in the future.
back to menu ↑Form Factor
Most of the motherboard in this price range are Micro ATX motherboards with a 9.6 inch by 9.6 inch dimensions.
You can also find ATX motherboards on the higher price side but the mini ITX are quite rare to find under this price tag especially if you choose to go for the newer chipsets.
back to menu ↑M.2 Slots
The A320 and A520 motherboards offer a max of single M.2 NVMe SSD slot. The B450 and B550 can offer 2 x M.2 slots.
back to menu ↑Overclocking
If you are an enthusiasts who loves tweaking their system, then we recommend sticking the B450 and the B550 chipsets.
The A320 or the A520 motherboards DO NOT allow overclocking.
This has mainly to do with the fact that in order to save cost, the A520 and the cheaper chipsets lack the amount of VRMs or the VRM heat sinks to stabilize voltage or temperature in overclocked situation.
back to menu ↑WiFi
The newer chipset, the B550 supports WiFi 6. The other chipsets, including the A520 lacks support for the newer WiFi 6.
back to menu ↑Frequently Asked Questions
back to menu ↑What Can You Expect From AMD Motherboards Under $100?
Motherboards under $100 are considered general purpose motherboards for home or office use. They bring the minimum specs to the table.
However, as seen above, there are a certain few motherboards under the $100 range that can provide you with an extraordinary value for your money if you are a gamer too.
Here are some of the things you can expect from AM4 motherboard from this price category:
back to menu ↑Chipset
There are four chipsets that you can usually find under this price range i.e A320, B450, A520 and B550. Of these four, the A320 and B450 are older and hence cheaper.
The A520 and B550 are newer and slightly more expensive.
We recommend that you stick with the newer chipsets because they support the latest processors from the get go. On the older chipsets you may have to update the BIOS to support newer Ryzen Gen 3 or 4 processors.
Also, it is worth nothing that the “A” series are the entry level chipsets, where as the “B” series are a mid range AM4 chipset.
We explore the characteristics of chipset in the sections below.
back to menu ↑PCIe Expansion
If you choose to go for A520 or the A320 chipset, you can only find a single PCIe x16 expansion slot because this chipset can only support a single GPU.
You may or may not find the smaller X1 slots.
The B550 and B450 are a bit more versatile. These can handle dual graphics card so you may find 2 x X16 slots here albeit the second X16 slot generally operates at X4 speed (enough to run an AMD card).
back to menu ↑PCIe Version
If you want to go for a motherboard featuring the latest PCIe V4.0, then B550 is the way to go. The PCIe V4, like all the previous gen, improves by doubling the lane speed.
An x4 lane on PCIe V4 can top 8 GB/s second. The same with a V3 can top only 4 GB/s.
Higher the transfer speed, the better and newer graphics card or other devices like SSDs you can install.
The A520, albeit new in the market, does not feature PCIe V4.0. Instead its GPU and general purpose lanes from the chipset all conform to PCIe V3. This is in contrast to the A320 chipset on which the general purpose lanes conformed to PCIe V2.
back to menu ↑WRAP UP
AMD’s popularity is on the rise, there are articles over articles these days singing the praise of the newer AMD processor as well as the graphics so it only makes sense that your next investment be an AMD setup.
In this article we look at the best AM4 motherboards under $100. Basically we look at motherboard that will be suitable for office/home use as well as for gamers who want to keep the cost of their motherboard to a bear minimum.
