Motherboard Asrock B550M Phantom Gaming 4

Asrock B550M Phantom Gaming 4 is a Micro ATX motherboard for the AM4 platform, aimed at a stable mid-range Ryzen build – from budget gaming to serious everyday work. The combination of AMD B550 chipset and PCIe 4.0 x16 slot gives you a current foundation for modern GPUs and NVMe SSDs. The four DIMM slots support up to 128 GB DDR4 memory with high frequencies at OC, so you have a good upgrade path. Plus, you get a decent set of M.2, SATA, USB, and video outputs for flexible configuration.

What you get

The AM4 socket and support for Ryzen 3000, 4000 G-Series, and 5000 processors allow you to build a system according to your budget – from APU with integrated video to powerful multi-core CPU. The memory is DDR4 in 4 slots with dual-channel mode and frequencies up to 4733+ MHz (OC), which is a plus for higher FPS and faster operation in applications. The two M.2 slots – one Hyper M.2 (PCIe Gen4 x4) and one M.2 (PCIe Gen3 x2 & SATA3) – give you the option for a fast system NVMe SSD and a second drive for games or projects. The four SATA3 6.0 Gb/s ports with RAID 0,1,10 are suitable for more storage or a small home “array” for data protection. The built-in LAN and 7.1 audio cover basic networking and multimedia needs without the need for additional cards.

• AM4 socket with B550 chipset – compatibility with Ryzen 3000, 4000 G-Series, and 5000 provides a wide choice of CPUs for gaming and work.
• Micro ATX form factor – fits easily into more compact cases without sacrificing key slots and connectors.
• 4 DDR4 slots, up to 128 GB and 4733+ MHz (OC) – sufficient capacity and frequency for heavy gaming, many browser tabs, and productive tasks.
• 2 M.2 slots – one Hyper M.2 PCIe Gen4 x4 for the fastest NVMe SSDs and one M.2 PCIe Gen3 x2 & SATA3 for additional storage.
• 4 x SATA3 6.0 Gb/s with RAID 0,1,10 – a good base for several 2.5"/3.5" drives and an option for higher speed or data redundancy.
• Expansion slots: 1 x PCIe 4.0 x16, 1 x PCIe 3.0 x16, 1 x PCIe 3.0 x1 – space for a main GPU plus additional cards like capture, audio, or network.
• Rich rear I/O – HDMI, DisplayPort 1.2, and D-Sub for integrated video, many USB 3.2 Gen1/Gen2 Type-A and Type-C, RJ-45 LAN, and 7.1 HD audio.
• Realtek ALC892/ALC897 7.1 audio and Realtek RTL8111H LAN with LANGuard – stable network and decent sound for gaming, movies, and chat.

Who it is suitable for

This motherboard is suitable for mid-range gaming and all-round PC builds with Ryzen 3000/5000, where you want PCIe 4.0 for GPU or NVMe and enough RAM slots for future upgrades. It is also a good choice for compact work machines that use fast SSDs and several SATA drives. If you are aiming for extreme overclocking or a build with many PCIe cards, you might want to look towards higher-end and larger form factors.

The most sensible aspect here is the balance between PCIe 4.0 capabilities, two M.2 slots, and rich I/O in a Micro ATX format – a stable foundation for a modern and long-term AM4 build.
