ASROCK B450M Pro4 R2.0 DDR4 AMD Motherboard

The ASRock B450M Pro4 R2.0 is a Micro ATX motherboard built on the AMD B450 chipset and designed for the AM4 socket. It supports AMD Ryzen 2000, 3000, 4000 G-Series, 5000, and 5000 G-Series desktop processors, making it a versatile platform for a wide range of AMD builds. At the heart of its power delivery is a 10-phase Digi Power design paired with a premium 42A power choke, enabling stable and efficient power distribution to the CPU across everyday workloads and overclocking sessions. The board uses a 2oz copper PCB with a High Density Glass Fabric construction, which contributes to improved thermal performance and signal integrity. Memory support spans four DDR4 DIMM slots with dual-channel technology and a maximum capacity of 128GB. Compatible speeds include DDR4 3200, 2933, 2667, 2400, and 2133 depending on the CPU generation installed, with XMP profile support for enthusiast memory kits. Storage options are generous for this form factor: four SATA3 6Gb/s ports support RAID 0, 1, and 10 configurations, while the primary Ultra M.2 slot (M2_1) accommodates PCIe Gen3 x4 NVMe drives at up to 32Gb/s, and the secondary M.2 slot (M2_2) supports SATA3 M.2 modules. Connectivity on the rear I/O is a highlight of this revision. Alongside four USB 3.2 Gen1 ports and two USB 2.0 ports, the board adds a USB 3.2 Gen2 Type-A port and a USB 3.2 Gen2 Type-C port, both delivering up to 10Gb/s. Display outputs include HDMI 1.4, DVI-D, and D-Sub, supporting triple-monitor setups when used with an APU featuring integrated Radeon Vega graphics. The onboard 7.1-channel HD audio is powered by a Realtek ALC892/897 codec, and networking is handled by a Realtek RTL8111H Gigabit LAN controller with Energy Efficient Ethernet 802.3az support. For RGB enthusiasts, the board includes one standard RGB LED header and one addressable RGB header, compatible with ASRock's Polychrome RGB Sync ecosystem. ASRock Full Spike Protection covers all USB, audio, and LAN ports, while the Sapphire Black PCB with solid capacitor design rounds out the build quality credentials.
