Buying Guide for the Best Ryzen 9 3900x Motherboards 

The above motherboards may sound similar to you. However, they differ based on what processors they support or form factor they have. Some can be overclocked while others limit the user to generic use.

So, here’s a more detailed buying guide where we’ll consider a few factors that you should keep in mind before buying a motherboard. These factors can help you make a better and informed decision. Here are the factors: –

1. Chipset

A chipset is of significant importance when you’re buying a motherboard. After all, the chipset decides what RAM, GPU, or other attachments you can use. Although all of the above motherboards support the Ryzen 9 3900X, still you need to check for the chipset.

2. Form Factor 

The form factor is another factor worth a mention here. You can think of the form factor as the size of the motherboard.

The largest and the most form factor is ATX, which is the size of most motherboards in the above list. So, you need to check whether or not your cabinet is big enough to house the ATX motherboard. There are other forms as well like micro ATX In GIGABYTE B550M DS3H. 

It’s smaller than the ATX and is quite compact. The smaller the size lesser is the expansion option. However, micro ATX helps in building a compact rig. So, the choice is yours.

3. Compatibility with the processor 

Processors have different versions or let’s call it generation, i.e., 1st gen, 2nd gen, or 3rd gen. It’s a crucial point you need to know about. Not every motherboard will support all of the above three generations. So, look for the generation of the processor and then match it with the motherboard.

The Asus ROG Strix B450-F supports all three generations. And on the other hand, the MSI MAG B550 TOMAHAWK Gaming Motherboard supports only 3rd gen. So, keep an eye on the compatibility.

4. PCI-e & Expansion Slots

Whether it’s memory or connectivity, more is better. The more expansion slots are available in the motherboard, the more you can customize it. There should be at least one for SSD connectivity, another for graphics cards, and 2 for installing RAMs.

You can also check for the PCI-E slots for attaching graphics cards, network cards, or sound cards. These expansion options can help you increase further your connectivity. So, look for a motherboard with maximum expansion slots if you want better connectivity.

5. M.2 Slots

You’ll need an SSD if you’re looking for a prompt response from your system. And for this, an M.2 slot is necessary. There’s at least one m.2 slot in every motherboard. However more is better. In the above list, you can find dual m.2 slots, which means you can easily install multiple SSDs.

6. Ports

Once you’re done checking the m.2s check other ports too. By other ports, we mean for attaching a keyboard, mouse, and other optical devices. Check whether or not you can connect WIFI or Bluetooth adapter. Check for an ethernet port too.

These days the latest motherboards come with multiple USB type C support too. You can also check the ports available for display. Check whether it has old display ports or the new type of HDMI ports.

7. Memory Slots

Every motherboard in the above list supports Ryzen 9 3900x. However, for the memory support, you need to check how many memory slots it comes with. The more the better. Fortunately, all of the above motherboards come with four memory slots. So, choosing any of the above won’t be a bad decision at all.


Updates are possible in your motherboard’s chipset using BIOS. With every update, the chipset upgrades and the performance improves. So, check whether or not the motherboard support bios updates. Usually, most motherboards support BIOS updates. However, you can check the company’s official website to confirm the same.

9. RAM Capacity

Check for the RAM capacity when you’re buying a motherboard. The more the better. If you’re an average gamer, you can opt for 64GB max RAM support. However, if you’re into hardcore gaming, go for the 128GB variant..

10. Socket

It’s necessary that your motherboard connects with or supports your motherboard and the CPU. The motherboards listed above come with AM4 sockets. These AM4 sockets support AMD Ryzen processors ranging from 1st and 2nd to 3rd generation.

11. Warranty

Warranty always helps. The more warranty you get with your motherboard the better it is. If there’s no information regarding warranty online shopping websites, visit the official website of the manufacturer. You’ll find a warranty there.
