ASRock B450 Pro4 is a versatile ATX motherboard based on the AMD B450 chipset that supports Socket AM4 processors and DDR4 3200+ (OC) memory for responsive performance in desktop builds.

This motherboard is compatible with AMD Athlon and AMD Ryzen 2000 and 3000 Series processors, and accepts a single Socket AM4 CPU for mainstream and enthusiast builds. The board provides robust power and cooling headers, including an 8-pin EPS connector, CPU fan header and three chassis fan connectors to keep your system stable under load.

Memory support is extensive with four DIMM slots that accept unbuffered DDR4 modules in dual-channel configuration, supporting ECC and non-ECC types up to 128 GB total and speeds up to 3200 MHz (OC). Supported module sizes include 4GB, 8GB, 16GB and 32GB which lets you scale RAM for gaming, content creation or workstation tasks.

Storage options include two M.2 slots plus six SATA III ports, giving flexible combinations of NVMe SSDs and traditional HDD/SSD storage. The board also supports RAID 0, 1 and 10 for data redundancy and performance tuning. SATA cables are included to simplify initial setup.

Graphics and display outputs are well covered with HDMI and DisplayPort (1.2) plus a legacy D-Sub (VGA) port, allowing up to three displays and supporting resolutions up to 4096 x 2160. Multi-GPU CrossFireX support provides additional flexibility for gamers and content creators who want to combine GPUs.

Connectivity includes Gigabit Ethernet via a Realtek RTL8111H controller with Wake-on-LAN support, a comprehensive USB complement with USB 2.0, USB 3.2 Gen1 Type-A and Gen2 Type-A and Type-C ports, and PS/2 legacy support. Onboard audio is handled by the Realtek ALC892 codec delivering 7.1-channel HD sound for immersive playback.

The ASRock B450 Pro4 includes a UEFI AMI BIOS (128 Mbit) with ASRock utilities such as A-Tuning, Polychrome RGB, XFast LAN and instant flash tools to streamline tuning and firmware updates. System monitoring covers CPU, fan, temperature, voltage and water cooling for effective PC health management. It officially supports Windows 10 x64 and Windows 11 x64 and carries CE/FCC and ErP/EuP certifications.

Use cases: the B450 Pro4 is ideal for cost-conscious gamers building an Ryzen-based rig, home office or multimedia PCs that need multiple displays and storage tiers, or entry-level workstations requiring ECC memory support and RAID. Key selling points include broad memory support to 128 GB, dual M.2 slots with six SATA III ports, multi-display outputs and a full complement of modern USB ports for peripherals.
