Starting with some of the cheapest offerings, as Asus Prime series of motherboards are targeted for budget users and professional work more than gaming. The one we've there is compatible with both Zen & Zen+ processors out of the box. This motherboard's core features are no different from the Asus Prime B450-Plus, where the controllers and memory support of them are also the same.

Aesthetically it also looks great, with its black-colored PCB and grey accents, making it very appealing in modern builds. You will not see any RGB lights on this motherboard for a reason as it's cheap enough and made for a budget-friendly build.

The Asus Prime B450M-A is an m-ATX motherboard, but its size is quite smaller than any other motherboard in that form factor. Two memory slots allow users to install memory up to 32 GB with a clock speed of 3200 Mhz. For storage, there is a single M.2 slot that lacks M.2 heat spreader and four SATA 6GBPS slots for further storage expansion.

The motherboard is best suited for entry-level builds; however, you can also use it for mid-range builds if you save for other components. APU users will appreciate that this motherboard has video output ports on the rear IO panel. The back panel also has a couple of USB 3.1 and USB 2.0 ports; however, it lacks the USB 2.0 port.

These features make this motherboard one of the best choices for building an entry-level gaming computer. Asus targeted this motherboard less for gaming and more for professional use, and that's what the Prime series is all about. You need certain features in a budget build for an entry-level build, and this motherboard can provide you with a solid foundation for your gaming build.

A budget motherboard that offers all the necessary features set but keeps it subtle, and that's the Gigabyte B450M DS3H. A single RGB strip can be connected to the RGB header on this motherboard, as the motherboard does not have integrated RGB lighting. This is the cheapest motherboard that we can recommend for Ryzen 3 2200G with display output ports.

Its controllers are usually found in the lower range of B450 motherboards, but they do a decent job for the price. Because of its features, this motherboard is better than its competitors that come at the same price. There are numerous ports on the back of this motherboard, including high-speed USB, video output, and audio.

Gigabyte B450M DS3H is extremely attractive since it has a black color base with some grey circuits printed on it, starting from the corners and going toward the CPU socket. This motherboard is geared toward entry-level builds, but still has four DIMM slots and two PCIe x16 slots that support AMD Crossfire technology.

The maximum memory support is 64 GB, and it is compatible with DDR4 3200 Mhz ECC and non-ECC memory modules. Furthermore, there are built-in XMP profiles for DDR4 memory. As for storage devices, there are four SATA slots and a single M.2 slot for high-speed NVMe.

This motherboard is excellent for an entry-level machine, and its features set it apart from its competitors. Two PCIe x16 slots and four memory slots make this the best motherboard to build a Ryzen 5 2600X based system, and it won't let you down.

Usually, I don’t recommend cheap motherboards, especially when considering AMD processors, because they may limit overclocking performance. ASRock's B450M PRO4 motherboard is among the cheapest options to consider for Zen+ processors while saving some money from this motherboard so it can be spent on other components. 

This motherboard is also available in a cheaper version from the same lineup named B450M-HDV, but I would recommend you stick with this one due to its price to performance ratio. The controllers of this motherboard may not be top-of-the-line, but they do their job at least perfectly.

One problem with this motherboard is that M.2 slots share PCI lanes with SATA slots, but two M.2 slots on a low-cost motherboard make it very attractive. This motherboard can overclock Ryzen 5 2600X fairly well, but only if you have some premium aftermarket cooler.

Aside from these few things, you won't be able to find any fault with this motherboard, and it'll amaze you with the features. The B450M PRO4 lacks Nvidia SLI but supports two AMD graphics cards with the AMD Crossfire technology. It is also compatible with 64 GB of DDR4 memory across four slots. 

The B450 Pro4 offers excellent value for its price and is a decent entry-level motherboard for Ryzen 5 2600X. An entry-level motherboard with two M.2 slots makes it more appealing to budget users. Based on the manufacturer's claim, this motherboard is made up of high-density fiber that has no spaces between PCB layers, making it difficult to be damaged by humidity.

As a budget chipset, most motherboards with the B450M chipset have dirt VRMs and a slim feature set. A number of premium motherboards are available with this chipset, but they are quite expensive, however, I’ve picked a budget-friendly premium motherboard for you. ASRock B450M Steel Legend is just as good as the entry-level B550 boards when it comes to overclocking performance and high-speed ports. 

The ASRock B450M Steel legend is a premium option with core features that we mostly find on premium boards and it comes at a very budget-friendly price. Like all mATX B450 motherboards, this one comes with four DIMM slots, a single M.2 slot without a heatsink, and four SATA III slots.

Since mainstream B550 chipset boards were released, getting an old B450 boards is not a good deal at all, but if you are considering budget or do not need a high-speed M.2 slot, B450 boards are a good choice. 

ASRock's B450M Steel Legend has a good VRM and it can handle some high-end processors like the Ryzen 9 3900X, but do not expect to overclock this beast. With fewer premium features and more premium looks, this is one of the best motherboard for Ryzen 5 2600X, especially when considering the budget. In addition, it is a great alternative to the B450M Gaming Plus and the B450M Mortar Titanium.

It has fewer connectivity options than B550, but still includes several USB 3.1 Gen1 ports, including Type-A and Type-C. It lacks integrated Wi-Fi or a 2.5G NIC, but it has awesome RGB lights, a great color scheme, and a built-in IO cover. Combining all of these features, we see why this board is appealing.

MSI B450 Tomahawk

M.2 Slots 1x

MSI B450 Tomahawk is one of the best offerings from the company with a B450 chipset because of its features as well as its VRM and cooling. This motherboard comes at a very budget-friendly price, but that doesn't mean you will have to compromise on the features as it has all the same features as Gaming Pro Carbon AC adds some less, which makes it a step-down version of it. 

The most popular features of this motherboard are its VRM cooling solution and the high-quality MOSFETs which help in better overclocking of the processor in comparison to other B450 chipset motherboards. VRM heatsinks go up to the IO section, but there's no IO cover like on the premium models.

The motherboard has four DIMMs that can accept a maximum memory of 128 GB clocked at 3200 MHz. One of the things that might disappoint you is the single M.2 slot, when on other motherboards we have two or even more. It also has six SATA III slots for further storage expansion. 

However, even though it looks like a budget motherboard, it still looks good in modern RGB builds, and performance-wise it is superior to any other B450 motherboard. The cons of this motherboard are that it does not feature a secondary M.2 slot, DisplayPort, or integrated Wi-Fi, but does feature onboard RGB lighting.

This is a great option for a gaming build if you don’t care about new and premium features and don’t plan to pair it with some high-end processor.
