Motherboard ASUS PRIME B550M-K WIFI AM4 - 90MB1R80-M0EAY0

ASUS PRIME B550M-K WIFI is a compact Micro ATX motherboard for AM4, aimed at a stable budget or mid-range Ryzen build. It combines support for AMD Ryzen 3000/4000/5000 Series processors with a modern set of connectors and built-in Wi-Fi 6, so you can assemble a clean and functional computer without unnecessary add-ons. DDR4 support up to 5100 MHz gives you room to squeeze the most out of your memory, while the PCIe 4.0 x16 slot is ready for a modern GPU. The board is a good core for a small case, where you seek a balance between price, capabilities, and reliability.

What you get

With an AM4 socket and support for third to fifth-generation Ryzen, you can choose a CPU according to your budget – from a basic office/home use to a serious multi-core chip for productivity and gaming. The two DDR4 slots with a capacity of up to 64 GB and frequencies between 2133 and 5100 MHz cover both standard and faster configurations – important for lower latency and better responsiveness in games and work. You have two M.2 slots (one up to 2280, one up to 22110), which allows you to install a fast system NVMe drive plus an additional M.2 device for games or projects. The four SATA III ports with support for RAID 0/1/10 are convenient if you need more space for data or want RAID for security or speed. The built-in Wi-Fi 6, Bluetooth, and 1Gb Ethernet give you full freedom in how to connect the machine to the network – whether it will be near the router or at the other end of the room.

• The AM4 socket with support for AMD Ryzen 3000/4000/5000 Series allows you to choose from a wide range of CPUs – from budget to powerful multi-core variants.
• Compact Micro ATX form factor, suitable for smaller cases, without sacrificing key slots and connectors.
• Two DDR4 memory slots with up to 64 GB and frequencies of 2133–5100 MHz, which is sufficient for both modern games and serious multitasking work.
• Two M.2 slots – 1x M.2 (up to 2280) and 1x M.2 (up to 22110) – for fast NVMe drives and more flexible SSD distribution.
• Four SATA III ports plus support for RAID 0, 1, 10, if you want a combination of speed, capacity, and reliability for your data.
• Built-in Wi-Fi 6 and Bluetooth, so you don't need an additional card for wireless connection and peripherals.
• 1Gb Ethernet, 4x USB 3.2 Gen 1 Type-A, and 2x USB 2.0 provide a decent set of ports for peripherals, external drives, and accessories.
• Standard power connectors – 24-pin ATX and 8-pin EPS – for compatibility with mainstream ATX PSUs.
• Expansion slots 1x PCIe 4.0 x16 and 1x PCIe 3.0 x1 for a modern graphics card and an additional card if needed (sound, capture, network).
• Built-in 7.1-channel audio for multimedia and gaming without a mandatory external sound card.

Who it is suitable for

This motherboard is suitable for a compact gaming or universal home/office Ryzen build with a decent GPU, a fast NVMe SSD, and up to 64 GB of RAM. It is a good choice if you want Wi-Fi 6 and Bluetooth directly from the board, without filling PCIe slots with additional cards. It is not the best option if you plan an extreme high-end build with many PCIe cards and tons of RAM modules – the form factor and the two RAM slots are limiting.

The combination of AM4 support for several generations of Ryzen, Wi-Fi 6, two M.2 slots, and a compact Micro ATX design makes the ASUS PRIME B550M-K WIFI a very reasonable foundation for a modern, tight, and functional build.
