MSI MPG X570 Gaming Pluheight
MSI MPG X570 Gaming Pluheight

Specs=”Chipset: X570 | Memory: 4x DIMM, 128GB, DDR4-4400 | Video Outputs: HDMI | USB Ports: 8x rear IO, 8x internal | Network: 1x 1 GbE LAN | Storage: 2x M.2, 6x SATA”]

We all know that this list would have seemed a bit incomplete without an MSI motherboard. The MPG X570 Gaming Plus is one of MSI’s hot-sellers, and for good reason. It bears an extremely reasonable price tag which makes it a great grab, particularly for gamers. 

For a mid-range motherboard, the MPG X570 Gaming Plus boasts a significantly better look as compared to its competitors. The PCB is a combination of black and red, and the heatsinks have a bit of a dark grey theme going on. The MSI and ‘Gaming Plus’ branding is also written in red, which is a nice touch. However, the RGB area is where Gaming Plus considerably loses its lead over its competitors in this price bracket. There is no addressable RGB lighting on the board, and that’s surely a bummer for our RGB lovers out there. Nonetheless, you can still install RGB fans onto it to light up your Ryzen 9 3900x Gaming Motherboard.

The voltage regulator features a 10-phase design in an 8+2 manner and is equipped with an IR35201 PWM controller. To keep the VRMs cool, MSI makes use of an extended heatsink design for effective heat dissipation. However, there is no heat pipe linking the two this time around. Over the chipset is a Frozr heatsink equipped with a double ball-bearing fan. Interestingly, the fan is implemented with zero frozr technology: an AI tuning system that adjusts fan speed as per the heat produced by the chipset, keeping noise levels low. 

Memory is one area where no X570 board slacks on, and it’s the same case with this board. It packs 4 DIMM slots with a 128GB memory capacity at 4400+MHz overclocked speeds. The storage offering on this board is adequate enough, with 6 SATA3 ports and 2 M.2 gen 4 slots. However, you might be surprised to see no M.2 heatsink screwed on the board. Well, worry not because MSI has you covered with an M.2 frozr shield in the box. The gen 4 lanes also extend to the two PCIe x16 and three PCIe x1 slots. 

The rear I/O panel, although well equipped, does lack a pre-mounted shield. Two USB 2.0 ports, four USB 3.2 Gen1 ports, and two USB 3.2 Gen2 (Type-A and Type-C) ports are present. Moreover, there is one PS/2 port and one optical S/PDIF out port. For wired internet, you have a LAN port housing the Realtek 8111H Gigabit LAN Controller. The gold-plated audio jacks are powered by the Realtek ALC1220 codec. Surprisingly, MSI has not compromised on the audio solution even at a sub $200 price-point. A BIOS flashback button is also present for easing the process of updating BIOS.

On the whole, the MSI MPG X570 Gaming Plus is targeted more towards budget gamers who want to run their Ryzen 9 3900x at stock settings with no tweaking and get adequate thermals. 

Pros

  • Great VRM Design
  • Versatile Connectivity
  • Relatively Affordable

Cons

  • No WiFi
  • One of the Best Looking X570 Motherboards

Moving down the list, we have our first motherboard that features the AMD B550 chipset. It’s MSI again, impressing us with yet another high-quality product, the MAG B550 Tomahawk. At a very reasonable MSRP, the Tomahawk is a feature-packed board that gives most premium X570 motherboards a run for their money.

The MAG B550 Tomahawk does a decent job in the aesthetics area, featuring a bold black-and-grey theme. MSI has been generous with the RGB LEDs on this board, as we see plenty of RGB LED strips around the chipset heatsink. You also get eight fan headers and two aRGB connectors to brighten things up a bit. The lighting can be controlled using the MSI Mystic Light software. In addition, the MSI and Tomahawk branding can be seen on many parts of the PCB. The heatsinks are quite chunky, which influences the overall look of the board in a rather subjective way. 

The power delivery on this AMD Ryzen 9 3900x motherboard is overseen by a 13-phase VRM in a 10+2+1 configuration. The Tomahawk makes use of MSI’s ‘Core Boost’ technology to attain accelerated CPU speeds with ease. The MAG B550 Tomahawk is also equipped with a surprisingly excellent heatsink design. As a result, you can run games on a range of settings without bumping into any temperature issues. The Tomahawk particularly handles Ryzen 3000-series CPUs quite nicely, so it is a great building block for your 3900x. MSI also includes the Dragon Center toolbox for you to monitor and configure your motherboard’s performance. 

The Tomahawk ticks all boxes in the memory sector, offering four DIMMs that provide 128GB of RAM capacity at 5100MHz. There are two M.2 slots, one of which supports both PCIe and NVMe while the latter only supports PCIe-based drives. You also get six SATA3 ports @6GBps, although some motherboards also provide eight ports in this category. As for graphics, there are two long PCIe slots, including 1 PCIe 4.0 x16 slot and 1 PCIe 3.0 x16 slot. Moreover, there are 2 PCIe 3.0 x1 slots as well. The proprietary x16 slots are protected with Steel Armor to provide strength and stability to the cards. We award the MSI MAG B550 Tomahawk as the Best Cheap Motherboard For Ryzen 9 3900x; it provides, budget, value, and excellent performance.

However, there is a dark side of this Ryzen 9 3900x motherboard too, more specifically the I/O panel. There are only six USB ports (although two of them are USB 3.2 Gen 2 ports, so that’s a positive point). There’s no built-in Wi-Fi module, and no PS/2 combo port as well. The Realtek ALC1200 audio codec is pretty underwhelming for today’s audio standards. On the brighter side, you get an ultra-fast 2.5GbE ethernet port along with another 1GbE ethernet port. An optical S/PDIF along with five analog audio jacks are also available. Lastly, HDMI and DisplayPort are also provided, giving you a variety of options for multimedia connectivity. For the 3900x, though, this isn’t exactly an advantage as the CPU does not support integrated graphics.

All things considered, the MSI MAG B550 Tomahawk is the best budget motherboard for Ryzen 9 3900x. It is not only an excellent choice for this particular chipset, but it is future-proof for the later Ryzen CPU generations as well.

Pros

  • Support For 2.5 GbE LAN
  • Excellent Price To Performance Ratio
  • Very Solid VRM

And last but definitely not least, we have another B550 motherboard in the micro-ATX form factor. It’s the MSI MAG B550m Mortar, a cheap motherboard specifically designed for more compact builds. The B550m Mortar cuts down on the gimmicks and provides features that are sufficient enough for any serious gamer. The result: an extremely manageable price tag that allows you to save your money and invest it in, for example, a better graphics card.

The MAG B550m Mortar boasts a pretty attractive design language. The PCB is quite a busy one, as a lot of components are crammed into a smaller form factor. The heatsinks and rear I/O cover are brushed silver, giving the motherboard a very elegant look. The MORTAR emblem is engraved on the chipset heatsink. As for the gimmicks we mentioned earlier, RGB lighting is one of them as there is no integrated RGB. The overall design pattern is reminiscent of MSI’s other premium X570 and B550 motherboards, such as the B550 Tomahawk.

An 11-phase VRM design configured in an 8+2+1 layout is responsible for providing pure and usable power to the components. MSI has implemented the extended heatsink design with an extra choke thermal pad for an improved thermal solution. They further claim to have thickened the PCB with copper for higher performance and non-stop gaming. The thermal performance of the Mortar is somewhat similar to the B550 Tomahawk, except for the smaller heatsinks and lack of a chipset fan. Pair it with a 3900x, and this board works like a charm.

Unlike most mATX form factor boards, the B550m Mortar has 4 full-fledged DIMM slots with a 128GB capacity at 4400MHz speeds. The storage section is another impressive specification of this Ryzen 9 3900x motherboard. It includes six SATA3 ports, one M.2 gen4 slot with heatsink, and one M.2 gen3 slot which is the standard in most mid-range B550 boards. The primary PCIe 4.0 x16 slot is armored with steel to avoid bending of the graphics card. Apart from that, one PCIe 3.0 x16 and two PCIe 3.0 x1 expansion slots are also available. Overall, it is safe to say that no corners have been cut off in this section of the motherboard.

Tips For Buying Ryzen 9 3900x Motherboard

Selecting motherboard is the most important part of a PC build. Although the above is a complete review and guide on best Best Motherboard for Ryzen 9 3900X in 2023 and now, hopefully, you are able enough to buy the best product as per your choice, some of you are still confused about choosing a product. The Ryzen 9 model of 3900X is a 12-core processor, which shocks the competition between Ryzen 9 3900X and Intel Core i9 processors. It’s powerful enough for high-end uses like video editing and playing AAA game titles, but it needs an equally capable motherboard. So, to help you out, we decided to make a list of the most important features that you, as the buyer, should consider before making the purchase.

Compatability of Processor

The first and the essential factor you should know is the compatibility of the processor with this motherboard. Processors come up with different generations, that is, the versions. You must know about it well. Every generation has no support with every motherboard. Every one of you knows that there are different processors, including Gen 1, Gen 2, and Gen 3, and more. So, it depends on which one you want to buy. After your choice and analysis, look for a motherboard that is compatible with your processor. Some motherboards including the ASUS brand and some MSI brand products, can support all processors of a certain generation.

Memory

Many users look for high memory, and some, on the other hand, don’t require high memory. So, it depends upon your need and which memory support you need for daily tasks. Some motherboards can support high memory of more than 32GM RAM, and some, on the other hand, have a short memory of less than 32GB RAM. You can check motherboards of qualified vendor lists for the sake of your confidence and assure the best quality. In other words, you can say that RAM capacity is an essential factor to consider.

Sockets & Chipsets

Some of the motherboards lack a couple of slots like RAM expandability, NVMe SSD slots, etc. If you are looking to get hold of SSDs and a pair of extra RAMs, make sure your motherboard has the option for slotting in more components. The other most important and vital feature is the chipset of a motherboard which determines how fast or slow your performance can be based on RAM, GPU, and Many other attachments with this device. Moreover, the chipset enables different features in the overall experience like Resizable Bar, Fast Boot, and Overclocking support.

Form Factor

It’s another important factor that needs to be addressed. There are three kinds of factors: ATX, Micro ATX, and Mini ATX. The most common one is the ATX form factor which comes in different sizes based on the number of DIMM slots available for memory. If you are replacing your old motherboard and don’t know the exact size, you can always measure the old one and get the one with the same size for accuracy purposes. If you bought a standard ATX, but your case only supports mini ATX, what will you do? Possibly, nothing! Your money is down the drain. So, it is required for you to select only those motherboards which are hostable in your case.

Expansion Slots & PCIe

A good gaming PC will require more than just a processor, graphics card, and ram. The ATX format is recommended because of its large number of expansion slots, and this makes upgrading easier down the line without having too many new components lying around already installed on-site so as avoid problems with compatibility issues during installation time frames. The PCIe slots are connectivity ports added to the motherboard which allow you to connect various peripheral devices to your systems, such as graphics cards, video cards, audio cards, and more. The more PCIe slots you have, the more connectivity option you will have. So make sure to opt for the motherboard that offers the connectivity of other hardware that you require.

BIOS

The BIOS is the pre-built software on the motherboard that is responsible for detecting the components connected to the motherboard and also forming a connection between various components. Motherboards come with BIOS, which need to be upgraded from time to time. Make sure that your BIOS is compatible with your processor; otherwise, the motherboard won’t be able to recognize it. Look out which motherboard offers the best BIOS set and BIOS recovery option.

Comparison of Ryzen 9 3900X vs 3700X vs 3600X

Whichever Ryzen 3000 processor you choose to buy, you’re going to have a capable PC ready for action. Even Ryzen 3 and Ryzen 5 processors are more than happy to keep up with some serious workloads, though they do come with fewer cores and lower clock speeds. All of the Zen 2 series processors, including the two in this guide, run on the AM4 platform and support the same AMD chipsets.

The AMD Ryzen 9 3900X is a monstrous CPU, boasting 12 cores in a small package with 24 threads at hand to handle any task you throw at it. It offers immense performance at a reasonable price, though you’ll dislike the lack of an integrated GPU. Also, while you are here, also check out Best Motherboard For Ryzen 5 3600.

Whereas The Ryzen 7 3700X is one of the worthy products for AMD’s series of processors. AMD of this processor is one of the most capable desktop processors the manufacturers, at present, we have the latest technology of Ryzen 9 and Threadripper. But 3700X still offers excellent value and is worth your money with six cores and a TDP of lower than the latest Ryzen 9 3900X if you don’t need all that performance.

The Ryzen 5 3600X is a little more down to Earth than the older model and is vastly more affordable, making it quite the processor for most gaming rigs and workstations. When you don’t need a mass of cores and threads, this CPU will be more than relaxed to play your favorite games and render all your media. While comparing to 3900X, both processors work well with RAM that’s clocked at 3200MHz, support AM4 chipsets, are built on the 7nm Zen 2 architecture, and even work with PCIe 4.0 hardware. At just 95W and 105W for the two Ryzen CPUs, you’ll also be able to avail an efficient cooler out of the box, which is essential in running the PC under a heavy workload.

How We Chose The Best Ryzen 9 3900x Motherboard

If you want the absolute best motherboard for ryzen 9 3900x, then there are several factors you should closely consider. Remember – determining our requirements while buying a motherboard, and going about the buying process accordingly is our ultimate goal. Though the list goes on and on, these are the most vital aspects to evaluate when purchasing the motherboard for Ryzen 9 3900x.

Chipset

Choosing a relevant chipset is the first fundamental part of buying a motherboard for your 3900x. AMD Ryzen processors are highly credited for their flexible compatibility, which is one of their primary selling points. The AMD X570 chipset is currently the top-of-the-line chipset you can get for your 3900x, with all the flagship features. The AMD B550 is another relatively cheaper option. If you are looking for something a bit more wallet-friendly, then even a B450/X470 motherboard is a decent choice for the 3900x. However, due to the lack of PCIe 4.0 lanes, we do not recommend the older 400 series motherboards.

Form Factor

Once you have made up your mind on a particular chipset, the next step is to decide which form factor to opt for. There are three main form factors to choose from: ATX, micro-ATX, mini-ITX. Naturally, smaller boards are less feature-packed than their full-sized ATX counterparts. Thus, it all depends on what you want – whether it’s the compactness you’re looking for, or a better feature set without having to make any considerable compromises.

Voltage Regulator Module (VRM)

It is essential to have sufficient, high-quality VRMs in your Ryzen 9 3900x motherboard especially when pairing it with a power-hungry processor. Cheap quality VRMs tend to degrade quickly, specifically when under persistent heavy loads. This ultimately has negative effects on your CPU’s performance. So, investing in a high-end CPU and cheaping out on a motherboard will cost you in the future. It is always wise to invest in a quality motherboard as the VRMs are much more stable and long-lasting. 

Upgrade Path From X570 and B550

Spending money on a motherboard for Ryzen 9 3900x time and again while frequently swapping it out is a hassle. Hence, it is beneficial to have prior knowledge about a motherboard’s CPU support. For example, the Ryzen 5000 series is likely to be the last batch of Ryzen processors officially compatible with 400 series motherboards (B450/X470). On the other hand, the B550 and X570 motherboards will have support for the next-gen processors. Therefore, it is better to loosen your pocket a bit and go for a newer motherboard. It will allow you to replace your older Ryzen 9 3900x processor with a later-gen processor, without having the need to change your motherboard as a whole.
