Intel has been the leading manufacturer when it comes to processors, and AMD tried catching up with their products for decades. With the release of the Ryzen 3000 series, AMD has been able to level up against Intel in an emphatic way finally. The Ryzen 9 3900X is one of the most beautiful creations by AMD. It is packing 12-cores and 24 threads, and it can easily give a tough time to any top of the line Intel processors.
AMD didn’t just stop there; it also threw the Ryzen 9 3950X into the mix, which is loaded with 16-cores and 32 threads. The most significant edge Ryzen has here is the price tag, and Intel is just failing to cut costs. For this reason, many content creators and gamers have switched towards Ryzen. The 3900X isn’t a mediocre processor, so you can’t expect to pair it with a cheap mobo. It requires a whopping 105W power input to get running, and that kind of power is only available on good boards.
The thing to understand here, especially if you’re a newbie, is that you can’t pair a top-notch processor with a cheap motherboard. There’s no point in buying it, and if you want to get the max out of your custom PC, you need to invest in things like motherboard, a sound graphics card, some compatible Ram sticks, and finally, an excellent case to set it all up.
The most compatible board with the Ryzen 9 3900X has to be the X570. However, you have the option to choose a B450 or even an X470 in this case. The choice of mobo depends on a lot of factors, such as form factor, your budget, and most importantly, if it can overclock your processor with ease or not.
Here are the 13 Best Motherboards for Ryzen 9 3900X that you can buy in 2020, and build the machine of your dreams:
1. MSI B450 Tomahawk Max
To start off, we’ve got the MSI B450 Tomahawk Max on the list. You can consider this as a budget board as it comes under the two-hundred-dollar range. It includes the AM4 socket, so it can handle the third generation AMD processors with ease. However, if you’re looking for something that will throw everything out of the park, then this might not be the perfect option for you.
If you look at the features, the board comes in the ATX form factor and has extended heatsink design to it. You can stuff it with up to four Ram sticks of your choice, and the max capacity is 128GB with the overclocking profile of 4133mhz. You get two PCIe × 16 slots on the board with heatsink options, and there’s one M2 slot as well for the NVMe SSD solution.
As far as pairing it with the Ryzen 9 3900X is concerned, one thing should be kept in mind that this isn’t the best option available. The main reason for that is because it doesn’t have a strong VRM solution to handle overclocking the 3900X. If you’re on a budget, and heavy-duty gaming isn’t your thing, then you can opt for this mobo with the intent of upgrading in the near future.
