Intel Z87 Chipset

The Intel Z87 Chipset supports Intel 4th generation Haswell processors and has many improvements over its predecessor. It offers native support for USB 3.0, SATA 6Gbps and support for Quad-Read speed SPI Devices. The platform would consume lower TDP, Idle and S3 power inside a smaller package (22mm x 23mm FCBGA). Manageability and security is significantly enhanced with next gen Intel vPro and Intel identity-protection technology. Improvements to Intel’s already implemented RST (Rapid Storage Technology and optimization's to the SSD performance have also been carried out.

Monitor Kit
status OLED

Status OLED

Status OLED shows various information of the system on a new high resolution OLED screen. Now you can use three buttons to toggle between information of the power on self test, debug codes, the current time, temperatures, frequencies and voltages of various points on the motherboard.

multi thermal sensor

Multi-Thermal Sensor

Multi-Thermal Sensor provides users the temperature of various parts of the motherboard graphically, so that users may precisely keep track and control the temperature of each part of their motherboard when overclocking.


Waterproof by Conformal Coating

Conductive liquids such as water pretty much destroy all kinds of electronics on contact. That’s why ASRock has implemented a special layer of Conformal Coating on our motherboards, which makes the motherboards invulnerable to conductive liquids, corrosion and dust. Users won’t have to worry about spilling liquid nitrogen, liquid helium or even clam chowder over their motherboards while overclocking.



Connect your PC and another device to one monitor and toggle between the primary and secondary screen without replugging the connectors every time.


Home Cloud

This motherboard supports remote wake with the onboard Intel LAN, so you can connect with your PC from anywhere in the world. You will be able to power your PC on or off, and monitor and take control of it remotely with another smartphone, tablet or computer.

Home Cloud

Wi-Fi 802.11ac

An exclusive 802.11ac Wi-Fi (5G Wi-Fi) module supports up to 867Mbps wireless networks. The ASRock’s new OC Formula/AC ATX motherboard also features Bluetooth v4.0.


Purity Sound

Purity Sound is a combination of several hardware, software audio solutions and technologies that will satisfy even the pickiest audiophiles.

Purity Sound
Power Kit
12 power phase design

12 Power Phase Design

With a 12 Power Phase Design, this motherboard features 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 Alloy Choke (PAC)

Compared to iron powder chokes, Premium Alloy Chokes highlight a special alloy formula which is able to reduce up to 70% core loss. Moreover, the revolutionary choke construction features a highly magnetic and heat resistant design increasing the board's lifespan.


Dual-Stack MOSFET (DSM)

By stacking two dies into one MOSFET, DSM provides larger die area and lower Rds (on), so the power supply for the CPU Vcore is more efficient.

Digi Power


This motherboard uses a digital Pulse-Width Modulation (PWM) design, providing CPU V-core voltage more efficiently and smoothly.


Multiple Filter Cap (MFC)

With the combined power of three kinds of capacitors, MFC allows users to overclock their PC rig to extreme levels without worrying about the hardware components.

Cooling Kit
Twin-power cooling

Twin-Power Cooling

Twin-power cooling combines active air cooling with water cooling. The ultimate heat pipe cooling design maximizes the system’s convection to expel hot air, providing better airflow and faster heat dissipation.

thermal compound

Thermal Compound

GELID Solutions GC-Extreme Thermal Compound is an added bonus that allows overclockers to stabilize the CPU's temperature.

8 Layer PCB

Eight-Layer PCB

The eight-layer PCB comes with four sets of 2-ounce copper inner layers, using only carefully selected copper materials for its PCB layers, delivering lower temperature and higher energy efficiency for overclocking.

Connector Kit
Distortion-free slot

Distortion-Free Slot

ASRock’s new pin design for the memory slots and PCIe slots that effectively reduces distortion and promotes performance.

high density power connector

Hi-Density Power Connector

With Hi-Density Power Connectors for the motherboard’s CPU power connector, you'll see a reduction of 23% power loss and decrease the connector's temperature up to 71°F (22°C).

gold finger

15µ Gold Finger

Compared to other boards that come with only 3 - 4µ gold, this motherboard provides 15µ gold within the CPU socket, DRAM slots, and PCIE x16 slots, thus delivering three times better performance than usual.
