ASROCK B550M ITX AC MOTHERBOARD

8 Power Phase Design

Featuring sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.

Premium 60A Power Choke

Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.

RULE YOUR OWN LIGHTING WAY – POLYCHROME RGB

This motherboard features onboard RGB headers and an addressable RGB header that allow motherboard to be connected to compatible LED devices such as strip, CPU fans, coolers, chassis and so on. Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects.

Dual Band 802.11ac WiFi

No one has time for weak WiFi signals and sluggish internet! That’s why this motherboard comes with a 802.11ac WiFi (2.4G / 5G WiFi) module which supports wireless networks and Bluetooth v4.2.

Hyper M.2 (PCIe Gen4 x4)

Supports the next generation PCI Express 4.0 M.2 SSDs, it is capable of perform twice the speed compared to previous 3rd generation, giving a lightning fast data transferring experience.

M.2 Armors

Good M.2 SSD protection is important for longevity and stability. ASRock provides a completed M.2 armor solution that makes SSDs to run in a certain low temperature.

AMD SMART ACCESS MEMORY

Conventional PC systems processor can only access a fraction of graphics memory and limits system performance. With AMD Smart Access Memory, the data channel gets expanded to harness the full potential of GPU memory, removes the bottleneck and increase performance.

Dual USB 3.2 Gen1 (Type-A + Type-C)

This motherboard has a pair of onboard Type-A and Type-C USB 3.2 Gen1 ports built on the rear i/o for supporting next generation USB 3.2 Gen1 devices and to deliver up to 5 Gbps data transfer rates.

Dual Graphics Outputs

Complete with two types of most used connectors! Packed with a HDMI + DisplayPort combo, you have more graphics output options now.

HDMI 4k @60Hz

Supports the most recent HDMI 4K 60Hz graphics output specification. With the larger bandwidth and increased frame rate, the motion on your screen becomes more fluid and less blurry.

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.

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.

Live Update & APP Shop

ASRock Live Update & APP Shop is designed for your convenience. We provide various apps and support software for users to download. You can also easily optimize your system and keep your motherboard up to date with ASRock Live Update & APP Shop.
