The arrival of the AMD B550 chipset is an exciting prospect for PC builders, as it’s the first to bring the potential of PCIe 4.0 to the forefront for mainstream builders. ASUS has a diverse selection of new motherboards to choose from with this chipset, and this useful B550 motherboard guide will help you figure out which one is right for you.

In ASUS B550 motherboards, the main PCIe x16 and M.2 slots are PCIe 4.0-capable. They also feature up to four USB 3.2 Gen 2 ports that clock in with a maximum supported speed of 10Gbps each. The chipset’s built-in lanes now have PCIe 3.0 connectivity as well, which is great to see. Additionally, AMD has noted that future CPUs built on the Zen 3 architecture will be fully compatible with B550 motherboards, making them a safe and long-lasting investment for people who wish to upgrade to those new processors down the line.

It’s time for an upgrade

ASUS’ suite of elite B550 motherboards pair AMD’s newest chipset with a slew of high-quality features. Top-notch Ryzen processors have plenty of powerful cores, and as such, they need voltage regulator modules (VRMs) that can give them the power they need without issue. ASUS B550 boards come with premium power delivery and powerful cooling technologies to take on this role. If you’re worried about RAM, don’t be; the entire B550 lineup supports overclocked memory, so you’ll be free to push for peak RAM performance as you please.

ASUS’ B550 motherboards are also excellent choices for people looking to put together a mainstream build as well. The number of M.2 slots and cooling measures has increased across the full B550 lineup compared to ASUS’ last series of motherboards, and the standard Ethernet speed for many of the boards has been raised to 2.5Gbps. Also, boards that feature Intel Wi-Fi 6 AX200 adapters offer excellent wireless speeds up to 2400 Mbps. Some even include a header that can be paired with ASUS’ ThunderboltEX 3-TR card, which enables you to take advantage of all the incredible benefits that Thunderbolt 3 brings to the table.

Clear and convenient audio

An exciting new feature that has arrived with ASUS’ B550 motherboards is AI Noise Cancelling Microphone software, which can dramatically reduce  background noise whenever you use a microphone on your computer. Whether you’re in an intense multiplayer match, making an important business call, or just chatting with a friend on Skype, you can rest assured knowing that the AI Noise Canceling Microphone utility will help your voice come through loud and clear.

Many people own headphones and headsets that require Type-C ports, but since Type-C is more commonly used for other peripherals, having to use one of those scarce Type-C ports for audio devices can be annoying. Thankfully, the ROG Strix B550-E and B550-I boards have a dedicated Audio Type-C port, freeing up more traditional Type-C ports for other uses. This port has two special features as well; its power supply is filtered to prevent any noise pollution, and a special control chip can also automatically detect the type of connected device so the port can be used for both audio devices and other peripherals as required. These boards also include a Type-C-to-3.5mm adapter that makes it easy to get connected no matter what type of headphones you’re using. This leaves plenty of room for other accessories.

Rugged and dependable works of art

Raw technical specifications are important, but attention to physical detail is critical, too. ASUS succeeds here as well; the UEFI interface is the core of your PC, and its sky-high reputation in the PC building community speaks for itself. On top of simple and intuitive overclocking settings, you can also make use of the Q-Fan Control utility to manage your cooling and ensure your system runs quietly.

If you’re all about RGB flair, these B550 boards have plenty of it. The Aura Sync RGB LED ecosystem is best-in-class, and ASUS’ Armoury Crate software allows you to control LED settings, overclocking, and system monitoring in one easy-to-use app. You can also find Gen 2 addressable RGB LED headers with per-LED control, near-zero latency, and automatic configuration throughout the B550 motherboard series.

Leverage the power of BIOS FlashBack™

One of the best things that AMD’s Socket AM4 platforms bring to the table is compatibility with future CPUs. New processors typically need new firmware to work properly, so if a new motherboard doesn’t ship with the latest available firmware, updating it can be a hassle if you don’t already have a compatible CPU. Thankfully, BIOS FlashBack™ support is present on ROG Strix and TUF Gaming B550 boards. This awesome feature helps you get your new build up and running without any hassle by letting you update to the latest firmware using a power supply and a USB flash drive.

Something for everyone

ASUS’ engineers have created a plethora of different B550 motherboards across three separate design families. ROG Strix boards sit at the premium level and have elite features like powerful VRMs well-equipped for overclocking, enhanced audio gear, and Ethernet and Wi-Fi 6 connectivity. These boards also have RGB LEDs, I/O shields, and ProCool power connectors for peak style and efficiency.

TUF Gaming boards are best for people buying at the mainstream level, as they blend high-end features and an emphasis on durability with prices that appeal to mid-range buyers. Finally, the Prime series is designed around providing reliable performance at an approachable, budget-friendly cost. This guide will go into detail about each board specifically so you can figure out which one is best for you.

ROG Strix boards offer premium performance

The ROG Strix line aims to bring premium hardware and performance to PC builders. Available in both ATX and ITX formats, these boards feature a sleek black aesthetic supported by expressive and colorful RGB accents. The integrated I/O shields look fantastic, but they also simplify installation as well, making the user experience that much better. The elite VRMs are well-equipped to deliver all the power the latest Ryzen CPUs need, while 2.5Gb Ethernet and optional Wi-Fi 6 support bring cutting-edge connectivity to the table.

Outfitted with SupremeFX S1220A audio, Japanese capacitors, dedicated signal traces, and EMI shielding, ROG Strix motherboards represent the pinnacle of motherboard audio.

The ROG Strix B550-E Gaming is the cream of the crop

The ROG Strix B550-E Gaming stands as the king of the hill of this series of motherboards. The AM4 socket is backed up by a strong 14+2 power stage VRM for reliable, boundary-pushing performance, while PCIe x16 SafeSlots support multi-GPU use in two-way SLI or three-way CrossFireX setups. This makes the motherboard a fantastic choice for gamers and creators alike, as the benefits of multi-GPU setups are felt in both areas. The B550-E is the only board in ASUS’ B550 series that has SLI support. 8+4-pin ProCool power connectors guarantee that power is delivered safely and with complete stability.

All of this explosive power requires cooling, and thanks to the B550-E’s six fan headers (including a dedicated AIO pump header), the motherboard provides everything you need to beat the heat. Q-Fan software controls with automatic fan speed detection and multiple presets make keeping your rig quiet and cool a breeze. The dual M.2 slots work with SSDs up to 110mm long, and both are protected with efficient top-of-the-line heatsinks to prevent thermal damage.

In today’s age, fast connectivity is a must. The ROG Strix B550-E delivers it consistently thanks to Intel-powered 2.5 Gigabit Ethernet and Wi-Fi 6 controllers that will provide you with the speed you need. There’s also Bluetooth 5.1 support available, too, so you can use compatible wireless peripherals with your rig.

USB connectivity is all over the ROG Strix B550-E. You get three USB 3.2 Gen 2 connectors (one Type-C and two Type-A) on the back, alongside an Audio Type-C port and a collection of both USB 3.2 Gen 1 and USB 2.0 ports. There’s also a USB 3.2 Gen 2 front-panel connector that’s designed with new PC cases in mind. The premium SupremeFX S1220A audio chip provides impeccable sound for gaming and music.

When it comes to aesthetics, the sleek futuristic look of the ROG Strix B550-E is complemented beautifully by trims of RGB LED lighting. A total of four RGB LED headers are available, but if you’re not a fan of colored lighting, they can be turned off. This gives the motherboard a stealthy all-black appearance. Additionally, FlexKey reset button remapping and BIOS FlashBack™ for updating firmware with no CPU or memory is present as well, bringing even more value to bear.

  • Oxford Guy - Saturday, June 27, 2020 - link

    I'll take the opportunity of providing my opinion about the current crop of B550 boards:

  • rocketman122 - Saturday, June 27, 2020 - link

    Indeed overpriced. I like how the others have caught up with asus and give a great option value for less. Ill invest the difference in other hardware. Asus-Overrated overpriced
  • Oxford Guy - Monday, June 29, 2020 - link

    No. The B550 release has been noted for prices being too high across the board.
  • rocketman122 - Saturday, June 27, 2020 - link

    That tuf labeling means nothing vs what it once was.

    Im done with asus. Never again. So many excellent offerings from others for much less
  • mooninite - Friday, June 26, 2020 - link

    What version are the Intel I225-V NICs? v1 and v2 are riddled with bugs. If it's a v3 then that might have the fix.
  • Slash3 - Friday, June 26, 2020 - link

    v3 variants should start making their way onto boards beginning at the end of this month, so they're all going to currently be v1 and v2.
  • shadowjk - Sunday, June 28, 2020 - link

    The manufacturer that actually tells whether you're buying defective goods or not, would presumably gain favour with the tech-savy.
    Despite this being anandtech, I suspect we will not be informed about whether which SKU to buy in order to get non-defective WiFi.

    I would be overjoyed if I was lease prove me wrong.
  • yannigr2 - Friday, June 26, 2020 - link

    NOT buying a motherboard that connects a gazillion of PCIe and M.2 slots on a chipset with only 6 lanes. Who do they try to deceive?
