Product information

Description

The ASRock B450 Pro4 R2.0 is an ATX motherboard with the AMD B450 chipset and Socket AM4, compatible with AMD Athlon and Ryzen 3000/5000 series processors. It supports up to 128 GB DDR4 memory across four DIMM slots, multiple PCIe slots including two PCIe x16 (Gen3) for discrete graphics, dual M.2 interfaces for high-speed SSDs, SATA III ports, Realtek Gigabit LAN, and onboard video outputs (D-Sub, DisplayPort, HDMI) with up to 4K resolution when using a processor with integrated graphics.

Advantages

The board features a 10-phase power design with Digi Power and premium power chokes for stable CPU power delivery and enhanced overclocking. Two-ounce copper PCB layers and solid capacitors improve thermal performance and longevity. Built-in RGB and addressable RGB headers support ASUS Polychrome-compatible lighting synchronization. Dual USB 3.2 Gen2 Type-A and Type-C ports on the rear I/O provide up to 10 Gbps transfer speeds. Additional features include Full Spike Protection, ASRock A-Tuning software, Live Update & APP Shop, and broad storage options with RAID 0/1/10 support.

Suitable for

  • Building a mainstream AMD-based desktop with Ryzen or Athlon CPUs
  • Systems that need multiple displays without a dedicated GPU (requires CPU with integrated graphics)
  • Users who want fast storage: NVMe M.2 SSD plus SATA devices
  • Enthusiasts planning moderate overclocking and system tuning

Key specifications

  • Form factor: ATX
  • Chipset: AMD B450
  • CPU socket: Socket AM4 (supports Ryzen 3000/5000 and Athlon)
  • Memory: 4 × DDR4 DIMM slots, up to 128 GB
  • PCI Express: 2 × PCIe x16 (Gen3), additional PCIe slots
  • Storage: Dual M.2 (one PCIe Gen3 x4, one PCIe Gen3 x2/SATA), SATA III ports, RAID 0/1/10
  • USB: Dual USB 3.2 Gen2 (Type-A + Type-C) on rear I/O
  • LAN: Realtek RTL8111H Gigabit Ethernet
  • Audio & video: D-Sub, DisplayPort, HDMI (HDMI supports 4K; integrated GPU required)
  • Special features: 10-phase power design, 2oz copper PCB, Solid capacitors, Full Spike Protection, A-Tuning

How to use

Install the motherboard into an ATX-compatible chassis and secure with standoffs. Mount a compatible Socket AM4 CPU and apply the recommended CPU cooler. Populate DDR4 DIMMs across the slots following the motherboard manual for dual-channel configuration. Connect storage devices to the M.2 slots or SATA ports and attach GPU(s) to the PCIe x16 slot(s) if required. Connect front-panel headers, power supply cables, and rear I/O peripherals including USB and network cables. Enter BIOS/UEFI to verify CPU, memory, and storage detection, configure boot order, enable XMP/DOCP profiles if needed, and update firmware via ASRock Live Update when available.

Usage recommendations

For improved thermal performance and overclocking stability, use a quality CPU cooler and ensure good case airflow. Install two-ounce copper PCB optimally cooled by case ventilation. Use NVMe SSD in the primary M.2 (PCIe Gen3 x4) for the operating system and frequently used applications, and enable AMD StoreMI if combining SSD and HDD for automated data placement. Keep BIOS and drivers updated via ASRock Live Update & APP Shop to maintain compatibility and stability.
