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 choice for your Ryzen CPU.
Best B450 ATX Motherboards:
MSI B450 Tomahawk
MSI’s B450 Tomahawk is one of the best selling AMD Ryzen motherboards. While you’ll need a BIOS update if you want to use it with a third-generation Ryzen CPU, it comes with a host of great features and at a very reasonable price.
To begin with, the A-XMP OC mode allows you to use memory at up to 3466MHz, which is plenty. There are four DIMM slots for a total of 64GB of DDR4 dual-channel memory. It’s also one of the few motherboards that have support for AMD’s two-way Crossfire technology that allows you to use two graphics cards alongside each other. The slots are also steel and protect cards from bending.
The motherboard is also loaded with plenty of features. You have MSI’s Game Boost, X-Boost, Gaming Hotkey, as well as a debug LED that lets you troubleshoot any potential issues with incredible ease. The VRM section is excellent as well, so you can comfortably overclock your processor if you find it necessary. It’s one of the best B450 motherboards for overclocking. The motherboard does come with an M.2 slot, and you can get speeds of up to 32Gb/s.
Last but not least, you get MSI’s Mystic Light RGB, that not only has RGB lights on the motherboard but also allows you to install additional RGB lights. All things considered, the B450 Tomahawk is one of the best B450 motherboards, especially for budget-oriented users who want excellence.
ASUS ROG Strix B450-F
If ever you’ve built a PC, you’ve heard of Asus’s Strix series of components. They have everything from motherboards and graphics cards to peripherals, and their ROG Strix B450-F motherboard is an excellent budget AM4 motherboard for just about everyone. Make no mistake, while we do say budget, the Strix comes with a host of features that you would think are reserved for Asus’s high-end motherboards, but they’ve trickled down to this model.
For starters, you have four DIMM slots for a total of up to 64GB of dual-channel DDR4 RAM at 3200MHz. The connectivity selection is excellent, with two NVMe M.2 slots, as well as gigabit LAN and USB 3.1 Gen 2 for great file transfer speeds. You’ll also get Asus’s 5-way optimization with Fan Xpert 4 and Auto-Tuning, which will create tailored overclocking profiles for your specific build.
The audio section is pretty good, with a Supreme FX S1220A and Japanese capacitors. It’s a great upgrade over the generic audio you’d get from competitors’ motherboards, and it’s an 8 channel audio system. The IO shield has been premounted so you don’t have to worry about it, and this makes installation a bit faster.
Last but not least, lovers of a flashier build will appreciate the Aura Sync RGB lighting and the addition of two RGB headers for additional lights.
Gigabyte B450 AORUS Pro Wi-Fi
Gigabyte’s AORUS lineup of motherboards has everything, from budget-oriented models that cover the basics, to high-end enthusiast models. The B450 AORUS Pro Wi-Fi is closer to the budget-oriented models, but still has a few interesting features that make it worthy of your attention. It’s got support for first, second and third-generation Ryzen CPUs, as well as ones with Vega graphics, so you can use pretty much any AM4 processor. You might need a BIOS update for 3rd gen, though, so keep that in mind.
The AORUS Pro Wi-Fi comes with four DIMM slots for dual-channel memory. There are also two M.2 slots for an SSD, both of which have a heatsink, and you also have Intel dual-band 802.11ac Wi-Fi if you’d rather stay away from ethernet cables. The sound section is also great, with Realtek’s ALC1220-VB making an appearance, and WIMA capacitors.
The B450 AORUS Pro Wi-Fi comes with Gigabyte’s RGB Fusion, which not only has RGB lights on the motherboard but also has additional headers for fans and RGB controllers. If you’d like a flashier build, this is a great way to get there. There’s also Smart Fan 5 with Fan STOP, so you can have a quieter build when your system isn’t under load. All things considered, it’s an excellent board for budget-oriented AMD users.
Best B450 Micro-ATX Motherboards:
MSI B450M Bazooka V2
MSI has a very extensive lineup of AM4 motherboards, both using the B and X series chipsets. However, none come even close to the price-to-performance ratio of the B450M Bazooka V2. It has a host of features at a very reasonable price, making it one of the best budget B450 motherboards, especially if you need a micro ATX board. So, what do you get with it?
For starters, you have four DIMM slots for dual-channel memory (up to 64GB), and you can use RAM that goes up to 3466MHz (OC), which is pretty fast, especially at that budget. There’s also an M.2 slot with support for AMD’s StoreMI technology.
You also have some of MSI’s trademark features, such as Core Boost, DDR4 Boost, and Audio Boost, as well as X-Boost which helps you get faster storage. The GPU slots are PCI-E Steel Armor, so you don’t have any bending on your graphics card. MSI’s Mystic Light makes an appearance here, so you can have RGB inside your case if you’d like a flashier build.
If you were to look around, you would find other boards that offer more functionality. However, none come close to the price point of the B450M Bazooka V2, especially not with a comparable feature set, making it the best budget B450 motherboard.
ASRock B450M PRO4
ASRock’s B450M PRO4 is a budget-oriented micro ATX motherboard that aims to offer the essentials for a decent AMD build, at the lowest price point possible. While it does succeed at keeping the price point incredibly low, many avoid it because it lacks any standout features. But if you don’t need those standout features, is the B450M PRO4 still worth getting?
To begin with, you can have any of the three generations of AMD processors on it, but you’ll need a BIOS update for Gen 3. There’s also support for water cooling, and you have a Digi Power, 9 power phase design. Memory support is pretty good, with up to 64GB dual-channel memory supported, at up to 3200MHz (OC), provided you’re using a Gen3 CPU.
You have two PCIe 3.0 x16 slots, but if both are in use, one runs at x8. You can still use it for two AMD GPUs in CrossFireX. What’s great, especially at this price point, is that you get two M.2 slots so you can have plenty of fast storage. With four SATA III ports, you can add traditional hard drives as well, for a bit more storage if you need it.
All things considered, if you only need the basics, and want to save a few bucks on your new build, by all means, go for it. But if you want extra features, there are better boards for a bit more money.
ASUS Prime B450M-A/CSM
While Asus’s bread and butter is their ROG gaming lineup, they’ve got some great products that aren’t a part of it. A great example is their Prime B450M-A/CMS motherboard, a budget variant that makes sure to cover all the basics, and then some, and comes at a very reasonable price. Should it be the base of your next micro ATX built? Let’s take a closer look at it and find out.
First things first, you have four DIMM slots, for a maximum of 64GB of dual-channel DDR4 memory at 3200MHz. You’re also getting an M.2 slot which takes 2242, 2260, 2280 and 22110 SSDs for some really fast storage. The audio section is taken care of by an 8-channel Realtek ALC887 codec with audio shielding and dedicated PCB layers. The Japanese capacitors give you a warm and natural sound without the need to get a dedicated sound card.
While it may not be the best overclocking motherboard, you do have a DIGI+ VRM section with a 6 phase digital power design. That’s part of Asus’s 5X Protection III, which also includes a SafeSlot Core, LANGuard, Overvoltage Protection and a stainless-steel back IO. The fanless design heat sink will keep things cool, which is another neat feature. The Prime B450M-A/CSM is an excellent motherboard if you want a well made micro ATX board, especially if you want that fancy RGB header, too.
Gigabyte B450M DS3H
Many people tend to stick only with Gigabyte’s higher-end AORUS motherboards, but they’re far from the only models in the brand’s lineup. There are some more budget-oriented models as well, and case in point, we’ve got the B450M DS3H, an excellent micro ATX board that comes at a very reasonable price and covers all the basics really, really well.
Kicking things off with memory support, you have four DIMMs ready for up to 64GB of memory. What’s great is that you can go up to 3600MHz (OC), whereas most of the competition tops out at 3200MHz. If you want fast RAM, this is the motherboard to go with.
You have an M.2 slot for an NVMe drive, as well as both an HDMI and a DVI-D display output. Speaking of outputs, you have six USB 3.1 ports, as well as eight USB 2.0. The days of sacrificing ports for a smaller motherboard are long gone.
Gigabyte also made sure to include their Smart Fan 5 technology which regulates how much the fans are spinning, as well as the noise they’re making. You’ll have a near-silent system when it’s not under load. You also get support for RGB Fusion, which is a header that lets you add an RGB strip and control it via software from Gigabyte’s app.
Best B450 Mini-ITX Motherboards:
MSI B450I Gaming Plus AC
While MSI does have quite a lot of ATX and micro ATX motherboards, their options are a bit more limited when it comes to mini ITX boards. Fortunately, they’ve got the B450I Gaming Plus AC, which should be your MSI go-to if you’re building an extremely small system. It comes at a pretty reasonable price, yet covers all the essentials if you’re going the AMD route.
To begin with, you have two DIMM slots for up to 32GB of memory, and you can use the A-XMP OC mode for up to 3466MHz. Even though this is truly a tiny motherboard, there’s still room for an M.2 slot, and it’s MSI’s Turbo M.2 for up to 32Gb/s of throughput.
You would expect a mini ITX board to be stripped down in terms of features, but MSI tends to disagree. You’ll find their trademark features, such as Audio Boost, DDR4 Boost, X-Boost, Core Boost, as well as their EZ Debug LED that is one of the easiest ways of troubleshooting your system. The PCI-E Steel Slot will protect your graphics card from bending when inserted, which is nice for durability.
Last but not least, you have Realtek covering you for both LAN (8111H) and audio (ALC887), so you’ll get respectable performance in both aspects. An excellent mini ITX board for any enthusiast.
ASUS ROG Strix B450-I
The ROG Strix B450-I is Asus’s way of showing you that a physically small build doesn’t have to miss out on any of the important features of a good enthusiast build. With support for AMD’s AM4 socket, it’s a great motherboard that gives you a very respectable feature set at a reasonable price. Is it worth it? Absolutely, but let’s take a look at some of the details.
As you’d expect from a mini ITX board, you have two DIMM slots, for a total of 32GB of DDR4 memory at a maximum of 3200MHz (OC). There’s a single PCIe 3.0 slot, and you get two M.2 slots for your storage. Compared to most of the competition’s single M.2 slot, this is pretty good. And you also have a heatsink on top of the drives, to keep them cool.
The audio section of the board is pretty impressive, with SupremeFX S1220A giving you excellent sound. We also shouldn’t skip the network section, since the B450-I comes with Intel gigabit ethernet, as well as 2×2 802.11ac Wi-Fi with support for MU-MIMO.
Add to all of this the AuraSync RGB that’s built-in, and the additional RGB headers that let you add more lights, and you realize that your small build can look as flashy or as discretely lit as you want it to.
Gigabyte B450 I AORUS Pro Wi-Fi
Gigabyte’s B450 I AORUS Pro Wi-Fi is an excellent motherboard for enthusiasts who want a no-compromise motherboard, but one that can fit in a tiny case. If this sounds like you, you’ll love the feature set and will find the asking price more than reasonable when you’re building your AMD rig.
With two DIMM slots, you can have up to 32GB of memory, but unlike the competition that often stops at 3200MHz, here you can go as fast as 3600MHz (OC), which is impressive in a micro ITX board. You get an M.2 slot, as well as four SATA III connectors for additional storage. There’s no shortage of ports either, with two USB 3.1 Gen 2 ports on the back, two USB 3.1 Gen 1 ports through an internal header, as well as two USB 2.0 ports through an internal header.
The excellent feature set doesn’t stop there and extends to both the networking and audio sections. You have an Intel Wi-Fi 802.11ac module, Bluetooth 5, as well as gigabit LAN. In terms of audio, you have a Realtek ALC1220-VB codec so you’ll get great audio without the need for a sound card.
Last but not least, a modern motherboard has to have RGB, and the B450 I AORUS Pro Wi-Fi comes with a multi-zone LED light, as well as additional headers that all support RGB Fusion 2.0.
