1 MSI B450 Tomahawk – Best B450 Tomahawk Motherboards for AMD Ryzen

The B450 Tomahawk is one of the most affordable motherboards on the market. Despite the low price, gamers and overclockers alike will be pleased with the capabilities of this board. The accessories are standard and include two SATA cables, I/O shield, M2 screws, build guide, driver DVD, and user manual. You get great fan headers that work in both PWM and DC modes. The design isn’t overly flashy and looks quite pleasing.

MSI B450 Tomahawk Specs:

  • Form Factor: ATX
  • Memory: 4 x DDR4 (128GB)
  • M.2 / SATA: 1 x M.2, 6x SATA 3.0 ports
  • PCIe slots: 1 x PCIe 3.0 x16; 1 x PCIe 2.0 x16; 3 x PCIe 2.0 x1
  • Audio: Realtek ALC892 Audio Codec
  • LAN: Yes
  • Wi-Fi: No
  • Manufacturer: MSI

Overclockers will be pleased…

Overclockers will be especially pleased to find a large heatsink over the VRMs to keep temperatures under control. The rear I/O lacks a pre-installed shield but offers the most common ports, including a BIOS flashback button. It’s an easy way to reflash the older BIOS version if an update has failed. The only constraint is the PCIe slots.

Even though the board offers two large PCIe slots, the top one is x16 and is directly wired to the CPU, while the bottom one is an x4 connected to the B450 chipset. There is also an internal header for the front panel USB 3.0. From an overclocking point of view, the 4+2 VRM configuration might seem slightly low, but MSI tries to compensate for this by using extra MOSFETs.

That’s not all…

There aren’t many differences between the Tomahawk and other boards featuring the B450 chipset regarding performance. Most memory and CPU benchmarks run fine, and the memory is overclockable from the XMP settings in the BIOS. Games perform well, although there are competing offerings from Gigabyte that have better numbers.

One of the best features on the Tomahawk is the USB BIOS Flashback. Suppose you ever had instances where newer AMD processors aren’t compatible with older boards due to faulty BIOS updates. In that case, the flashback feature solves this issue by directly flashing a BIOS from a USB drive without actually needing to mount a CPU.

Our verdict?

Overall, the MSI B450 Tomahawk is one of the best budget friendly motherboards for the 2nd gen AMD Ryzen platform. It has plenty of useful features, and the USB BIOS flashback is an excellent addition to an already great B450 board.


MSI B450 Tomahawk

2 MSI B450I Gaming Plus AC – Best Rated B450 Motherboards for AMD Ryzen

Apart from the more common ATX board, the B450I is also available as a mini-ITX motherboard. Mini-ITX boards are perfect for building compact PCs saving space but still including enough features for a good gaming and overclocking experience.

However, considering the dimensions, there are some restrictions you should know about. For example, there is only one PCIe x16 slot. Should you need more, you might want to opt for a PCI riser, splitting the x16 bandwidth into 4x and 4x. This shouldn’t be an issue since the B450I doesn’t support and SLI configurations.

MSI B450I Gaming Plus AC specs:

  • Form Factor: Mini-ITX
  • Memory: 2 x DDR4 (64GB)
  • M.2 / SATA: 1 x M.2, 4x SATA 3.0 ports
  • PCIe slots: 1 x PCIe 3.0 x16
  • Audio: Realtek ALC887 Audio Codec
  • LAN: Yes
  • Wi-Fi: Yes
  • Manufacturer: MSI

The board has some limitations …

There is also only one M.2 slot directly linked to the CPU for PCIe Gen 3, x4 speeds. Other than that, the B450I Gaming Plus AC is similar to other MSI motherboards that have crossed our path so far. You can install both ECC memory and Non-ECC memory, but the memory itself only runs in the non-ECC mode.

One limitation is that the board doesn’t offer USB Type-C connectivity; instead, you get USB 3.1 Type-A. Apart from the Intel Gigabit Ethernet controller, the board also includes onboard wireless AC and Realtek ALC7 audio codec.

Our verdict?

If you’re looking at the B450I Gaming Plus AC, you will be enticed by the overall value in the package. You won’t get fancy RBG or overclocking options, or even any onboard advanced controllers. However, when it comes to performance, this Mini-ITX is easily on par with some of the more expensive ATX boards available and is one of the best B450 boards for HTPCs and mini PCs.

3 Asus ROG Strix B450-F Gaming – Best Mid Range B450 Motherboards for AMD Ryzen

If money isn’t an issue and you need more flexibility from the B450 platform, the Asus ROG Strix B450-F Gaming is the board for you. The Strix has two M.2 PCIe x4 slots, three PCIe x16 slots, and three PCIe x1 slots, giving you plenty of expansion options. This motherboard is for the gaming crowd, but it doesn’t have any unnecessary RGB overload.

Lighting effects can be found on the VRMs and the chipset heatsink, and that’s it. There are, of course, enough headers if you want to add your lighting strips.

ASUS ROG Strix B450-F Gaming specs:

  • Form Factor: ATX
  • Memory: 4 x DDR4 (128GB)
  • M.2 / SATA: 2 x M.2, 8x SATA 3.0 ports
  • PCIe slots: 2 x PCIe 3.0 x16, 1 x PCIe 2.0 x16, 3 x PCIe 2.0 x1
  • Audio: Realtek ALC1220-VB Audio Codec
  • LAN: Yes
  • Wi-Fi: No
  • Manufacturer: Asus
  • Support for 128GB of RAM

The Strix B450-F supports up to 128GB of DDR4-DIMM memory. And the SupremeFX audio gives you an isolated distortion-free sound with the Nichicon audio capacitors, producing a clean, clear output. Even though BIOS is standard for ASUS motherboards, you might find that it lacks features like XMP settings and manual core voltage settings, compared to the more expensive X470 boards.

Both the board and chipset are better suited for automatic overclocking through AMD’s Precision Boost and XFR, as opposed to manual overclocking, and in this regard, the B450-F excels. However, recent updates to BIOS have added some of the missing features. If you demand total control of how your components work, we recommend looking at the X470 boards instead of the B450.

The B450-F makes gaming a delight…

Gaming on the B450-F is a real delight, and it’s compatible with all the latest games at their highest settings. The only limitation is your GPU and CPU setup. There isn’t much difference between the B450-F and X470 chipsets, if only for a few overclocking and extra PCIe lanes.

But are they the Best B450 Motherboards for AMD Ryzen you can buy?

B450-F gaming is a good choice for building a budget gaming PC with a solid foundation for future upgrades. The price also includes a nice set of accessories and an ample amount of expansion slots. And if you’re keen on customization, you can swap out the stickers on the heatsink for your own.


Asus ROG Strix B450-F Gaming

Our rating:4.7 out of 5 stars (4.7 / 5)

Pros

  • Good for gaming.

4 ASRock B450M-HDV – Best Budget B450 Motherboards for AMD Ryzen

If all you need is a no-frills board that performs well without overwhelming you with different options, the ASRock B450M-HDV is your best choice. It’s one of the best Micro-ATX B450 AMD motherboards available. Despite the small form factor, it’s a competent board.

ASRock B450M-HDV Specs:

  • Form Factor: Micro-ATX
  • Memory: 2 x DDR4 (32GB)
  • M.2 / SATA: 1 x M.2, 4x SATA 3.0 ports
  • PCIe slots: 1 x PCIe 3.0 x16, 1 x PCIe 2.0 x1
  • Audio: Realtek ALC887 Audio Codec

  • Manufacturer: ASRock

The B450 chipset includes plenty of features for mainstream computing. ASRock takes it to another level thanks to its implementation of a 7-phase power design that supplies steady voltage if you decide to overclock your Ryzen CPU.

If that’s your aim, we recommend that you pair this motherboard with the Ryzen 5 2600X, rather than with the Ryzen 5 2600, as the X version automatically increases its clocks based on the available temperature and power limits.

But you should know…

Since this board doesn’t have as many overclocking features as the more high-end ASRock boards, going for an “X” CPU is a good option that saves you the inconvenience of fiddling about with voltage settings.

The board comes with most of the standard connectivity features, including the ability to use ECC and non-ECC RAM modules. But keep in mind that the Ryzen processors can’t make use of the ECC memory even if you install them.

Our verdict?

Considering the size of the Micro-ATX, you need to be aware of some limitations. For example, you can only use two memory sticks, so you want to opt for the maximum RAM and speed your budget allows. The board has some issues when configuring XMP profiles for the faster RAM modules, so you should go for the 2933 to 3000 MHz range to avoid any problems.


ASRock B450M-HDV

Our rating:4.4 out of 5 stars (4.4 / 5)

Pros

  • Affordable.
  • Nice set of features.
  • Suitable for small PCs.

Cons

  • Limited RAM expansion.
  • Issues with setting XMP profiles.

  • Audio: Realtek ALC892 Audio Codec
  • LAN: Yes
  • Wi-Fi: No
  • Manufacturer: ASRock

Let’s take a look at the essentials. The board’s backside has an excellent selection of ports, as well as a PS/2 if you want to go old-school. The board has four SATA ports and two M.2 ports, so there’s plenty of storage options. The M.2 ports can be used for SSDs that support SATA 3.0 and PCIe Gen3 with theoretical speeds up to 32GB/s.

The board also has three PCIe slots and four DDR4 DIMM slots, allowing up to 64GB of RAM. And you’re presented with a single Gigabit LAN port. So, as you can see, you get an excellent foundation for building a gaming PC with plenty of slots for expansion.

Some of the unique features…

When you look at the unique features, the ASRock PRO4 has plenty to offer. It has USB 3.1 Gen2, supporting speeds up to 10GB/s. It also provides Full Spike Protection, meaning that the motherboard is protected from sudden voltage spikes. The PRO4 is also one of the few motherboards that support up to three displays at once.
