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. SSDs are fast, but expensive, and offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. 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: SSD responsiveness, and mechanical hard disk capacity. You can also use up to 2GB of RAM as a last-level cache for ultra-fast data.

*AMD StoreMI software is only free with 400-series chipset based motherboards.

Dual M.2 For SSD

Equipped with M.2 slot that supports both SATA3 6Gb/s and PCIe Gen3 x4 Ultra M.2 interface that pushes data transfer speeds up to 32Gb/s, and is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen3 x4 SSD.

Dual USB 3.1 Gen2 (Type-A + Type-C)

This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear i/o for supporting next generation USB 3.1 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.

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 with A-Series APUs only.

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.

ELNA Audio Caps

Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream and entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3uA. This is the key to reduce noise level significantly and satisfy even the pickiest audiophiles.

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.

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.

A great board for the price. The only real let down is that there's only one PCIe 16 slot, the other slot actually only runs PCIe x4. That said, it gives a good chance at upgrading in the future and expanding when you need to.

The motherboard is excellent value for the money. While it does not have the best feature set that money can buy it has enough for normal use, it has good heatsinks over the VRMs, especially if you don't plan on overclocking and will now be compatible with 4000 series Ryzen CPUs. Considering that this boad design is the same as ASRock used for their F4tal1ity gaming motherboard, just with a inferior set of ports it is well worth buying if you don't want to break the bank for a feature rich B450 motherboard.

Was able to pair this with a bios update to support 3rd gen Ryzen so product is great. Just had to be careful that it would be compatible with other processors

Mike

last month

Really nice high quality board with 4 RAM slots which is great for future expansion to 32GB. Good fit and no flex when pushing in the RAM and M2 drive. Manual is not too clear for novices and incredibly small type face but the value for money and quality of this board makes it a 5 start product.

A very good value B450 motherboard. Lots of USB connectivity and a very easy to use UEFI/BIOS. Recommended for a good value Office/Home or a Mid Range Gaming PC.

Really great mobo, easy to build onto. Instruction manual was nice and clear to follow in regards to vRAM and other connection ports.

gigabyte are my normal go to motherboards but i heard(buildzoid) this was amazing. and it is, i havent had an ASrock in years i was really impressed.

Phil

June 2019

Excellent value board for running a Ryzen CPU. No frills like RGB lights and other extras but good quality hardware and capable of overclocking.

James McCallum

Works well and as expected

Dipak

June 2019

Motherboard worked perfectly with the Ryzen 2200G, there were no RAM compatibility issues whatsoever. Haven't tried any overclocking as the machine wasn't built as a games machine. Decent placement of SATA and PWM headers. Nothing bad to say about it really.

Dinakar

May 2019

Very good motherboard. Good heatsink and full functionality for cheap price.

Customer

April 2019

Good motherboard for ryzen 2600x very easy to get stable 4.2ghz all core overclock and let my ram timings drop to cl15 with ease

Mark Farmer

March 2019

Great mobo for the price. Best value mid-range board in my opinion. Some good features for the price, 2 M.2 slots, USB C and four ram slots.

Paul

February 2019

Perfect for my build at a reasonable price. However not 5 stars as the memory slots only clip at one end resulting in the possibility of incorrectly seated ram. Also PC speaker was disabled by default in bios so took a while to work out what the problem was when the PC started but kept resetting without passing POST.

Great little budget board and will definatley be more than enough for the average gamer. Came as expected and very pleased with the purchase!
