Motherboard ASROCK B550 PRO4

ASROCK B550 PRO4 is an ATX motherboard for AM4, aimed at a stable mid-range Ryzen build with upgrade options. It is based on the AMD B550 chipset and supports 3rd Gen AMD AM4 Ryzen / Future AMD Ryzen, so you can comfortably plan for a stronger CPU later. With DDR4 support up to 128 GB and an official frequency of up to 4733+ MHz (OC), the board allows for serious RAM configurations. Add to that a PCIe 4.0 x16 slot and modern M.2 options, and you have a very sensible base for gaming or work.

What you get

The four RAM slots with dual-channel mode give you flexibility – you can start with 2x8 or 2x16 GB and then simply add more modules up to 128 GB, without changing everything. The Hyper M.2 slot with PCIe Gen4 x4 is perfect for a fast NVMe SSD, while the second M.2 (PCIe Gen3 x2 & SATA3) allows for an additional SSD without sacrificing SATA ports. With 6 x SATA3 6.0 Gb/s, you can comfortably connect several HDD/SSD for games, projects, and backups, plus RAID 0/1/10 depending on whether you are chasing speed or redundancy. The built-in 7.1 CH HD Audio (Realtek ALC1200) is more than sufficient for gaming and movies, without the need for a separate card. The Gigabit LAN controller Realtek RTL8111H with Wake-On-LAN, ESD protection, and Energy Efficient Ethernet is a good plus for a stable network and 24/7 machine.

• CPU socket AM4 with AMD B550 chipset means support for 3rd Gen AMD Ryzen and future Ryzen models for long platform life.
• 4 DDR4 slots with dual-channel mode and up to 128 GB RAM at frequencies up to 4733+ MHz (OC), providing serious resources for gaming, streaming, and productivity.
• 1 x PCIe 4.0 x16 and 1 x PCIe 3.0 x16 plus 2 x PCIe 3.0 x1 offer enough space for a powerful GPU and additional cards, supporting AMD Quad-GPU CrossFireX and 2-Way CrossFireX.
• 2 M.2 slots – one Hyper M.2 (PCIe Gen4 x4) for maximum SSD speed and one M.2 (PCIe Gen3 x2 & SATA3) for flexible storage configurations.
• 6 x SATA3 6.0 Gb/s with support for RAID 0, 1, 10, suitable for both gaming libraries and more serious storage arrays.
• Built-in 7.1 CH HD Audio (Realtek ALC1200) with Content Protection offers clear sound for games, music, and movies without an additional audio card.
• Realtek RTL8111H Gigabit LAN with Wake-On-LAN, ESD protection, and Energy Efficient Ethernet 802.3az provides reliable network connectivity.
• Rich rear I/O panel with HDMI, D-Sub, USB 3.2 Gen2 Type-A and Type-C (10 Gb/s), plus several USB 3.2 Gen1 and audio jacks covers the needs for modern peripherals.
• Additional M.2 Key E slot for WiFi allows you to easily add wireless networking without losing a standard PCIe slot.
• 24-pin + 8-pin + 4-pin power connectors provide stable power for the CPU and motherboard, especially with more powerful Ryzen models.

Who it is suitable for

ASROCK B550 PRO4 is a good foundation for a mid-range to serious gaming build with Ryzen, as well as for a workstation with plenty of RAM and fast NVMe storage. It is suitable if you want PCIe 4.0 for modern GPUs and SSDs but do not need extreme enthusiast features. If you are chasing maximum OC, two high-end graphics cards, and a super luxurious set of extras, you will likely look towards higher-end boards.

The most sensible aspect of this model is the combination of the B550 chipset, PCIe 4.0 x16, dual M.2 with Gen4, and rich I/O, giving you a solid and future-proof foundation for an AM4 build without unnecessary embellishments.
