ASRock B450 PRO4 R2.0 AMD AM4 ATX Motherboard

The ASRock B450 PRO4 R2.0 is an ATX motherboard designed for AMD Ryzen processors on the AM4 socket. Compatible with Ryzen 2000, 3000, and 5000 series desktop processors, this motherboard delivers reliable performance for gaming and productivity builds.

Memory and Expansion

Supporting up to 128GB of DDR4 memory across four DIMM slots with speeds up to 3200MHz (overclocked), the B450 PRO4 R2.0 provides ample capacity for demanding applications. The board features two PCIe 3.0 x16 slots and four PCIe 2.0 x1 slots, with AMD Quad CrossFireX support for multi-GPU configurations.

Storage Options

This motherboard includes six SATA III ports and dual M.2 slots for high-speed storage. The first M.2 slot supports PCIe Gen3 x4 with transfer speeds up to 32Gb/s, while the second supports both PCIe Gen3 x2 and SATA3 M.2 modules. RAID 0, 1, and 10 configurations are supported for enhanced data protection and performance.

Connectivity

The rear I/O panel provides comprehensive connectivity including dual USB 3.2 Gen2 ports (Type-A and Type-C) delivering 10Gbps transfer rates, four USB 3.2 Gen1 ports, and two USB 2.0 ports. Additional USB headers on the board support two more USB 2.0 and one USB 3.2 Gen1 front panel connection. Gigabit Ethernet via Realtek LAN ensures reliable network connectivity.

Graphics Output

Three display outputs (D-Sub, HDMI, and DisplayPort 1.2) support triple monitor setups when using Ryzen processors with integrated graphics. The HDMI port supports 4K resolution for high-definition displays.

Power Delivery and Build Quality

The 10-phase power design ensures stable voltage delivery to the CPU with enhanced overclocking capabilities. ASRock's Super Alloy design incorporates premium power chokes, solid capacitors, and 2oz copper PCB layers for improved thermal performance and durability. The digital PWM design provides more efficient CPU Vcore voltage regulation compared to analog power delivery.

Audio and Software

7.1 channel HD audio powered by Realtek ALC892/897 codec delivers quality sound output. ASRock's A-Tuning software provides system monitoring and optimization tools, while Full Spike Protection safeguards sensitive components from voltage surges. AMD StoreMI technology combines SSD speed with HDD capacity for intelligent storage management.

Package Contents

Includes two SATA data cables, M.2 mounting screws, and comes with a 2-year replacement warranty.

Dual USB 3.2 Gen2 (Type-A + Type-C)

This motherboard has a pair of onboard Type-A and Type-C USB 3.2 Gen2 ports built on the rear i/o for supporting next generation USB 3.2 Gen2 devices and to deliver up to 10 Gbps data transfer rates.

2oz Copper

It comes with 2 ounces copper inner layers, using only carefully selected copper materials for PCB layers, delivering lower temperature and higher energy efficiency for overclocking.

AMD StoreMI Technology

A powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive, AMD StoreMI technology "combines" these two types of storage into a single drive and automatically moves the data you access the most to the SSD, so you get the best of both worlds.





Super Alloy Motherboard
Premium Power Choke
Compared to traditional chokes, ASRock's premium power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
Sapphire Black PCB
Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.
2oz Copper PCB
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.



3 Graphics Outputs

Complete with all three types of most used connectors! Packed with a D-Sub + DisplayPort + HDMI combo. Plus the HDMI port supports 4K resolution.
*Supported only with processors with integrated graphics. Please check CPU support list from each motherboard webpage.



Triple Monitor

Graphics, graphics and even more graphics! You've demanded for more eye candy, so this motherboard supports Triple Monitor. You may choose up to three display interfaces from the rear i/o to connect monitors and use them simultaneously without installing another graphics card.
*Supported with processors with integrated graphics only.



Solid Capacitor Design

ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably and ensure longer lifetime.




Digi Power

Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.




A-Tuning

A-Tuning is ASRock's multi purpose software suite with a new interface, more new features and improved utilities.




Full Spike Protection

Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard's components from being damaged by these unexpected voltage spikes.
