Buying the right motherboard is one of the most important steps when building or upgrading a PC. Therefore, with the release of Ryzen 3000 CPUs, it is important to choose a motherboard that has a good VRM and the essential features. As a result, below we have reviewed the 10 best B450 motherboards for Ryzen CPUs.

VRMs, fan headers, memory compatibility, and wireless connectivity are some of the many important features that motherboards offer. Yet many people are not knowledgeable or just don’t take into account some of those features and just go straight for the cheapest option. You need to know what motherboard you’re buying and why you’re buying it. Therefore, the B450 motherboards below should help you make the right and the best b450 motherboard for your Ryzen CPU.

Before we dive into the review, here is a B450 motherboard buyers guide to help you make the most informed choice;

Motherboard Buyer’s Guide

There are a lot of features to be mindful of when choosing what motherboard to get and quite frankly it can feel like an impossible challenge. If you are building a PC from scratch, you have probably researched all of the tiniest parts that go into making your computer and all of the information has probably merged into one big jumble in your head. 

We have put together a buyers guide to give you a helping hand and to make sense of the complicated tech jargon that is involved. 

Here are the top features and specs that great motherboards have along with a little bit of information about each one;

  1. Motherboard size – ATX, Micro-ATX, Mini-ITX- Which is Best?

There is no easy way to answer this as it all depends on what your specific needs are. If you need more than 4 PCIe slots then the ATX would be the right one for you as it is the largest of the three. 

The Micro ITX form-factor is an all-rounder and the one most people should opt for. The Mini ITX is the smallest and is only suitable in very small and compact computer setups. 

2. Compatibility

The compatibility of your computer components is extremely important, especially when you are chopping and changing between component manufacturers. There are a few ways of ensuring that all of your components are compatible with one another. 

Firstly, it is highly important that the processor you have can be connected to the motherboard you wish to get. You can check this by looking at the motherboard CPU socket and see if it matches your processor. 

Next, check the motherboard GPU configuration. The GPU is important because it links multiple video cards together. 

The amount of RAM the motherboard supports is incredibly important. 4GB RAM is on average what users need, any less than that and you run the risk of not having enough. 

3. DIMM RAM Slots

Motherboards can have as few as 1 RAM slots, or as many as 8. Most users feel that 4 DIMM slots are more than enough and most motherboards have 3 or 4. If you need a lot of RAM, consider getting a motherboard with more DIMM slots. 

4. Chipset

The chipset is a data flow management system. This manages all of the data that flows from the processor, memory and all the rest. Motherboards have anything from 1 to 5 chipsets. 

5. Overclocking

Overlocking is the action of running the CPU at an increased speed using the motherboard. Some basic motherboards do not support overclocking. So, if overclocking is important to you, keep your eyes peeled for the motherboards overclocking abilities in the features. 

6. Design 

The motherboards design is more important than you may think initially. If all of its card slots and connection pieces are crammed together, it can overheat and malfunction frequently. 

Think about how you are designing your PC and how the motherboard will fit into the construction. Designing a new PC or upgrading an existing one is not an easy challenge and one that takes careful consideration. 

7. Aesthetics

Some motherboards are visible when connected to the computer. A motherboard sits under the hard drives and can be extremely bulky and unattractive if it is the right style for your PC. Make sure that your motherboard is the right shape and size for your computer to avoid bulking up the overall look.

Have a look at other home-built computers and pay attention to the aesthetics of the motherboards other people have chosen. Have a look at how other people have positioned their components to produce an aesthetically pleasing PC.
