For customization, a user can add lights with RGB LED strip headers in both regular and Gen 2 addressable flavors. All come with Aura Sync support for easy configuration.

ROG STRIX B550-I Gaming

ROG STRIX B550-I Gaming is designed for small builds with big ambitions. By design, Mini-ITX makes room for a single PCIe 4.0 x16 slot, but the compact form factor has other advantages. STRIX B550-I Gaming can drive compatible DIMMs at speeds up to 5100 MHz and beyond. This is achieved by taking advantage of the shorter trace length between the memory slots and the CPU. The 8+2 power stage VRM is a fine fit for 3rd gen Ryzen chips. Active cooling on the VRM ensures that power delivery remains stable in the tight confines of Mini-ITX enclosures.

The preinstalled I/O panel is kitted out with USB 3.2 Gen 2 Type-C and Type-A ports. For networking, an Intel I225-V 2.5 Gbps Ethernet, an Intel AX200 WiFi 6 and Bluetooth 5.1 adapter are bundled in. Small machines are more likely to use more external storage, so ASUS added a front-panel USB 3.2 Gen 2 connector too. The 3.5 mm connectors are all LED lit in unique colors to allow for easy identification when connecting audio acessories. There’s a companion noise-filtered USB-C Audio port for microphones and headsets, too.

ASUS TUF Gaming B550-Plus

ASUS TUF Gaming B550-Plus features an 8+2 DrMOS voltage regulator module. Multiple generously-sized heatsinks atop the VRM, chipset and M.2 slots ensure all primary components stay cool under load. The primary PCIe 4.0 x16 slot is backed by SafeSlot reinforcement for extra-heavy graphics cards. A ProCool auxiliary connector with solid-core pins offers added peace of mind when using power-hungry CPUs. Two M.2 slots both accept devices as long as 110 mm, while the duet of PCIe x16 slots supports CrossFireX configurations. The rear panel includes USB ports of every modern type, and that can be further expanded with Thunderbolt 3 connectivity thanks to an onboard header. A BIOS FlashBack button rests near one of the ports for CPU-less UEFI upgrades.

TUF Gaming B550-Plus comes with Intel’s 2.5 Gbps Ethernet adapter and an M.2 E-key slot available for WiFi 6 and Bluetooth 5.1 upgrade. The Realtek S1200A audio codec in this model is further enhanced by DTS Custom support for headset 3D surround-sound virtualization. This audio setup makes movies and compatible games come alive with pinpoint-accurate positional audio.

The gray-and-black TUF Gaming aesthetic and its yellow accents is distinctive on its own. But this color palette can be improved more with additional lighting through LEDs. A Gen 2 addressable RGB LED header and two standard headers can be wired to additional strips for easy visual customization.

TUF Gaming B550M-Plus (WiFi)

ASUS TUF Gaming B550M-Plus (WiFi) takes many of the features of TUF Gaming B550-Plus and manages to fit on a smaller mATX footprint. This board keeps the same pairs of PCIe x16 and M.2 slots as its ATX sibling. The main difference is that one of the M.2 slots takes in standard 80 mm
devices instead of longer 110 mm units. In exchange, this model offers a more attractive price tag to go with its trimmed dimensions.

TUF Gaming B550M-Plus comes in two variants: with or without wireless. An Intel AX200 WiFi 6 and Bluetooth 5.1 controller and antennae are included in the WiFi model.

It comes fitted with heatsinks atop the VRM and chipset to ensure stability. Dual PCIe x16 slots support CrossFireX if a user needs dual-GPU action for their system, while the duo of M.2 slots accepts 110 mm drives. If the USB 3.2 Gen 2 ports around back aren’t enough, the optional ASUS ThunderboltEX 3 card can be installed. This expands the number of available ports, as well as support devices needing Thunderbolt to connect. The neutral colors exhibited by Prime B550-Plus is understated enough to fit into any build, but it’s also a fine base for adding in LED lighting.

ASUS Prime B550M-A (Wi-Fi)

Space in offices and bedrooms can be tight, making ASUS Prime B550M-A (Wi-Fi) a better option to go for where a normal ATX build might not. This variant of the Prime B550-Plus offers nearly the same specs but uses the compact microATX form factor. Due to the WiFi 6 standard, this motherboard is now perfect for situations where cables can pose more of a problem. For that reason, ASUS offers Prime B550M-A with Gigabit Ethernet only or in a version that includes an Intel AX200 WiFi 6 and Bluetooth 5.1 adapter.

ASUS Prime B550M-K

A microATX form factor lets builders save on space without sacrificing expandability.
