Best Am4 Motherboards Under 100 – BUYER’S GUIDE

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.

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).

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.

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.

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.

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.

WiFi

The newer chipset, the B550 supports WiFi 6. The other chipsets, including the A520 lacks support for the newer WiFi 6.
