Complement that AMD builds with the Prime B550 Plus AM4 ATX Motherboard from ASUS. Designed for the AM4 socket and using the B550 chipset, this motherboard can support up to 128GB of DDR4 RAM with frequencies up to 3200 MHz or, if overclocking, up to 4800 MHz. Users can also connect up to six SATA III drives and up to two M.2 drives ranging from 2242 to 22110. One of these slots benefits 3rd Gen AMD processors with PCIe 4.0 x4 performance, while the other slot features PCIe 3.0 x4 speeds. The Prime B550 Plus also supports RAID 0, 1, 10, and 5 for more resilient data storage, and CrossFireX allows for multiple-GPU setups. In addition to one M.2 PCIe 4.0 x16 slot and one M.2 PCIe 3.0 x16 slot, users have access to three PCIe 3.0 x1 slots.
In addition to water- and air-cooling components, the B550 Plus's internal threaders offer support for two USB 3.2 Gen 1 and four USB 2.0 Type-A ports, as well as a Thunderbolt 3 connection and a TPM for BIOS integrity. The back I/O panel also sports single USB 3.2 Gen 2 Type-A and Type-C ports, alongside four Gen 1 Type-A ports. Two USB 2.0 ports also provide connections for a mouse and keyboard, while monitors can be connected via the HDMI or DisplayPort outputs. Five 3.5mm ports are present for audio, alongside a S/PDIF port. Audio is handled by the Realtek ALC887 7.1 Channel Audio codec and takes advantage of shielding and separate layers for the left- and right-side channels, reducing common audio bugaboos such as interference and crosstalk. An ARGB header is present, and the inclusion of ASUS Aura sync allows users to not only match the Prime B550 to their current setup but also offers central control for compatible RGB components. This motherboard comes with two SATA III cables, as well as a support DVD and a screw package for mounting M.2 SSDs. The ASUS Prime B550 Plus is compatible with the Windows 10 64-bit operating system.
With the Energy Processing Unit, or EPU, you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with an away mode.
Fan Xpert 4 software provides comprehensive control over fans, water pumps, and all-in-one or AIO coolers. Whether cooling with air or water, and Auto-Tuning mode allows you to configure all parameters with a single click. There's also an Extreme Quiet mode that reduces all fan speeds below the default minimum to keep your system quiet when performing light tasks. Fans, water pumps, and AiO coolers can also be controlled via the UEFI BIOS.
The Digi+ voltage-regulator module or VRM delivers real-time control over voltage drop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for stability and performance.
Two VRM heatsinks with thermal pads underneath to improve heat transfer from the MOSFETs and chokes for better cooling performance.
The Prime B550 series features cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS. Furthermore, each header can dynamically reference three thermal sensors. And, with Fan Xpert 2+, you can map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks. The Prime B550-Plus also features a dedicated PWM/DC header for self-contained water-cooling setups and onboard chassis fan headers supporting PWM and DC control.
Numerous USB ports support high-end rigs loaded with peripherals, including a USB Type-C and Type-A connector with USB 3.2 Gen 2 connectivity for compatible cases. The Prime B550-Plus also supports ThunderboltEX 3-TR, an Intel certified Thunderbolt 3 add-on card that enables bidirectional speeds of up to 40 Gb/s via a single cable. Additionally, an integrated Thunderbolt 3 header can support up to six devices in a daisy-chain and provide up to 100W of power to fast-charge devices.
PCIe 4.0 M.2 slots support drives up to 22110 and provide NVMe SSD RAID support for a performance boost. Create a RAID configuration with up to 64 Gb/s PCIe 4.0 storage devices to take advantage of the 3rd Generation AMD Ryzen platform. One M.2 slot supports PCIe 4.0 and one supports PCIe 3.0.
Audio shielding Separates analogue and digital signal domains, reducing the chance of multilateral interference. There are also separate layers for left and right tracks, ensuring lower crosstalk between audio paths.
ASUS Aura offers full RGB lighting control with functional presets for RGB LED strips connected to the onboard RGB headers. And, it can all be synced with Aura-capable hardware.
The addressable Gen 2 RGB header is now capable of detecting the number of LEDs on second-gen ARGB devices, allowing the software to tailor lighting effects to specific devices. This header also offers backwards-compatibility with existing Aura RGB gear.
Armoury Crate is a software utility designed to give you centralized control of supported products. From a single interface, Armoury Crate allows you to customize RGB lighting and effects for compatible devices in your build. The software also provides control of settings for ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and highlight to help you stay in touch with the ASUS community.

Whether you build a new PC or upgrade the existing one, the motherboard is the most vital component to choose when you have already picked the processor of your choice.
It is important to keep a few things in mind while purchasing the mainboard:
You can single out a great CPU from either Intel or AMD, but whatever CPU you choose, make sure your mainboard has the right socket for the selected CPU. The latest mainstream AMD chips use AM4 sockets while current Intel 9th Gen Core CPUs require LGA 1151v2 sockets.
Motherboards typically come in three sizes from largest to smallest: ATX, Micro-ATX, and Mini-ATX motherboards. ATX motherboards offer the highest number of RAM and expansion slots. If you are looking for a budget build, you can use a smaller chassis with the micro or mini boards, but you'll have to settle for fewer PCIe slots, RAM banks, and other connectors.
Most mainstream boards these days have four RAM slots, although Mini-ITX models often have just two, and high-end boards frequently offer eight. The amount of slots, of course, limits the amount of RAM you can install.
It’s essential to check the I/O area on a motherboard to make sure it has the external connection options you need. You may need more USB 3 ports while others may want more audio ports. Among the most common ports, there are USB 3, USB 2, audio, USB type C, USB 3.1 Gen1 and Gen2, HDMI, Display port, PS/2 and Thunderbolt 3 ports. Ports one probably want the most are USB 2 and USB 3 Gen1 ports, as the first one is perfect for keyboard, mouse, and many other devices and the later one work with most peripherals. USB 3.1 Gen2 and USB Type-C ports will come handy in the near future, although most peripherals do not support this standard yet.
