*Please refer to the product specification page for more detail.
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.
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.
Premium 42A Power Choke
Compared to traditional chokes, ASRock’s premium 42A 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.
High Density Glass Fabric PCB
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
2oz Copper PCB
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
This motherboard uses a next generation Hybrid Digi Power design to bring precise control and smooth power. With the ensured efficient and clean power delivery to the CPU, the stability and lifespan of motherboard is also greatly enhanced.
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.
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.
3 Graphics Outputs
Complete with all three types of most used connectors! Packed with a D-Sub + DVI-D + 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.
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.
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.
