For example, when you boot up the computer, the LED light will indicate replacing certain parts like video cards or CPUs.

That’s quite impressive, considering that you may not know about it until it’s too late.

The LED colors will indicate a specific part that needs to be replaced, repaired, or updated.

For example, the LED light will light up yellow while booting, indicating issues with your computer’s RAM.

Another thing is that this motherboard is quite easy to install. Even if you have never even built a gaming PC from the ground up, you won’t have a hard time installing this along with the rest of the compatible components.

The Bad

One of the things that we didn’t like about the Asus ROG Strix B450 F-Gaming Motherboard was the episodes of random rebooting.

Whether you are a gamer or upgrading your office computer, you can’t go wrong with investing in a motherboard that can run efficiently.

One of the best things about the ASRock B450-HDV Motherboard is that it will be easier to add more RAM sticks.

If the amount of RAM you may have isn’t enough, you can add another one.

It also clocks very well with most AMD Ryzen CPUs, which are preferred by most gamers.

We weren’t joking when we said that you are getting excellent performance at a reasonable price.

The ASRock B450-HDV Motherboard is also fast, which obviously will be the number one thing every computer user wants.

The Bad

The ASRock B450-HDV Motherboard will handle plenty of RAM. However, when you are overclocking the system, you may have problems in terms of booting it up.

  • Works with more recent AMD Ryzen CPUs
  • Easy to install
  • Easy to upgrade

CONS

  • Overclocking can lead to boot up problems

3. Gigabyte B450 AORUS M Motherboard

The previous motherboard didn’t support 1st or 2nd generation Ryzen CPUs and GPUs. This does.

The Gigabyte B450 AORUS M Motherboard might be what you’re looking for if you’re planning on upgrading your current computer.

It can work with almost every Windows OS that has come out in the last decade.

Sadly, it likely won’t support anything beyond Windows 7.

Product Highlights

The Gigabyte B450 AORUS M Motherboard has dual-channel non-ECC unbuffered DDR4.

This is perfect when you need plenty of memory to run your machine. The more you have on hand, the better.

It also has an audio system that will work to your advantage if you’re looking for something that will give you a clean, crisp sound.

With high-quality audio capacitors and noise guards, you’ll be satisfied overall.

If you are someone who enjoys LAN gaming, you’ll love the fact that this motherboard has a Gigabyte exclusive 8118 gaming LAN.

If you want to keep your computer running cool without risking any overheating, the Smart Fan 5 with fan stop will be a welcome addition to any computer that will be compatible with this motherboard.

Finally, you have USB ports that will come in handy whenever you need to plug in more appliances like external hard drives, keyboards, and more.  

The Good

One of the things that we like about the Gigabyte B450 AORUS M Motherboard is it has the ability to work with Windows 7 of all operating systems.

It’s been around for years, and we now live in the Windows 10 world. But if you can’t seem to let it go, you’ll need a specific CPU.

Specifically, you’ll need to install an AMD Pinnacle Ridge and Summit Ridge CPU.

It also never compromises quality, especially the high-quality features that the Gigabyte B450 AORUS M Motherboard possesses.

Another thing we like is the BIOs on this motherboard were easy to navigate.

Meaning setup is a breeze, and you could have your computer up and running in no time.

The Bad

We didn’t like the location of the M2 drive on the Gigabyte B450 AORUS M Motherboard. It’s below the graphics card.

It could mean the parts could be susceptible to damage due to overheating.

So you may want to consider refraining from overclocking while this motherboard is intact with your computer.

The Gigabyte B450 AORUS M Motherboard won’t accept large-sized graphics cards either.

PROS

  • Supports a handful of RGB components
  • Easy to install
  • Compatible with some of the older versions of Windows

The Prime B450M Micro-ATX Motherboard just might be one of the best-looking motherboards on the market.

It’s well designed and is easily compatible with AMD and Ryzen CPUs.

In short, it’s one of the best motherboards for gamers who are serious about building a high performing machine with excellent graphics, rich sound, and fast speeds.

Product Highlights

If you are looking for fast connectivity, you have it with the inclusion of the 1GB LAN and HDMI 2.0 port as part of the ASUS Prime B450M Micro-ATX Motherboard's features.

You can play the games you want without worrying about lagging. This motherboard also has the best protection you can offer from overvoltage and overcurrent.

That means your computer won’t have to sustain any damage that may occur during sudden power surges.

As such, you don’t have to worry about replacing any parts that may get fried.

The ASUS Prime B450M Micro-ATX Motherboard will give you more than what you’ll pay.

If you are building a gaming PC from the ground up, there is no doubt that you can do it on a budget!

The Good

We like that the ASUS Prime B450M Micro-ATX Motherboard provides all kinds of stability.

That means you can plug things in without having to worry about everything going haywire.

After all, it’s what you want in a motherboard regardless if you built it from scratch or upgraded from the one that came with your current PC.

Another thing that we were impressed with is the inclusion of updated BIOs straight out of the box.

They are easy to navigate and set up. By the time it’s set and ready to go, the PC will run smoothly without a hiccup.

The Bad

One thing that didn’t sit well with us is the placement of some of the ASUS Prime B450M Micro-ATX Motherboard's components.

Specifically, the graphics and wireless cards. When overclocking, overheating can lead to potential damage to one or both of the cards.

The lack of dual video is another thing that we considered to be bad. If you wanted to improve the video quality with an extra card, certainly you should have that option.

  • Good overclocking support
  • Great value for money

CONS

  • Graphics card and wireless cards should be apart

Lastly, we have the Arsenal Gaming AMD Ryzen ATX Motherboard. MSI has gained quite a bit of popularity with gamers in recent years.

Not only will it handle AMD Ryzen CPUs regardless of the generation, but it also has superior overclocking support.

That’s because it has a built-in heatsink that will make sure your PC doesn’t get way too overheated whenever you want to overclock it for performance.

This will even work to ensure that whatever high-end processor you choose, your PC will run at a ridiculous rate of speed. Your inner gamer must be salivating at this point.

Product Highlights

The MSI Arsenal Gaming AMD Ryzen ATX Motherboard has DDR4 memory support.

That means you’ll be able to install memory sticks if you feel you need more of it for your PC.

It was made for the gamer who wants nothing more than the best possible setup both inside and out.

The MSI Arsenal Gaming AMD Ryzen ATX Motherboard has an extended heatsink, which will absorb plenty of heat.

As such, your gaming PC doesn’t get too hot even when you overclock it for performance.

Nine times out of ten, the average PC gamer will overclock their system to maximize the performance beyond its abilities.

You’ll get excellent speeds thanks to the inclusion of an M2 with 1x turbo and fast USB 3.2 ports.

The gamer deserves speed, and you’re going to get it with the MSI Arsenal Gaming AMD Ryzen ATX Motherboard.

The Good

What else can we say? Other than the fact that it’s lightning-fast, well-designed, and pretty much sets the stage for putting together a killer set up.

Think about it: you have a nice surround sound system connected to the HD audio connectors. You have plenty of memory.

Plus, the graphics are by far the best you’ve ever seen on a gaming computer.

If that won’t make you the envy of the gaming world, we’re not sure what will. 

The Bad

One of the things we didn’t like was the lack of information regarding the BIOs set up.

The instruction manuals don't give you much. Not to mention, the language is poorly written anyway.

Some users have reported the MSI Arsenal Gaming AMD Ryzen ATX Motherboard being a bit buggy right out of the box.

Nevertheless, it will work just fine once everything is set up.

PROS

  • Super fast
  • Well-designed
  • Plenty of connectivity
  • Great memory support

  • BIOS may be hard to set up at first
  • May not have enough USB ports

Buyer’s Guide

If our B450 motherboard reviews weren't enough to help you decide what's best for you, this buyer’s guide would help.

Below are the important features you need to look for and understand.

CPU Compatibility

Not all motherboards will be compatible with every CPU on the market.

That is especially if they are made from the same brand. If you already have a CPU that you want to purchase, it can whittle down your choices on which motherboard is perfect for it.

That’s why you need to pay close attention to which motherboard will work with certain processors by doing a little deep digging.

Sites like UserBenchmark will help you determine if one of the best B450 motherboards will work with your choice CPU.

RAM/Memory

The more RAM or memory you have, the better. That’s because it plays a major role in making your computer as responsive as possible.

A higher memory capacity also means increasing the frame per second (FPS rates).

Some games will run smoothly at 60 FPS, while others may run at double the amount at best.

Connectivity and Ports

Remember that you would need to connect and plug multiple components into the motherboard. Thus, find one that can support your needs.

You must also consider the location of these ports and connectivities.

Expansion Slots

Apart from ports and connectivities, it's advisable to choose a motherboard with plenty of slots for expansion, such as:

  • PCI (Peripheral Component Interconnect)

As the oldest standard expansion slot type, PCI accepts sound cards, LAN adapters, and more, so you can add a lot of great features.

  • Video Card

Some motherboards have embedded video adapters, so you can't install a separate video adapter card.

Others have a special slot for expansion slot that will accept a standalone PCI Express or AGP video adapter card.

You'll also find motherboards with no embedded video adapters but have either an AGP or PCI Express slot.

It's always best to choose a motherboard that accepts separate video adapter cards.
