## Long 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.
