CREATE YOUR UNIQUE LIGHTING STYLE – POLYCHROME RGB

ASRock Motherboards offer amazing spectacle and beautiful aesthetics with unique lighting styles! ASRock offers extensive control over built-in RGB LEDs and connected RGB accessories such as LED strips, CPU fans, and case coolers.

Dual M.2 for SSDs, Support M.2 Type 22110

Two of the world's fastest M.2 ports. One offers PCIe Gen3 x4 32Gb/s connectivity, the other works in PCIe Gen3 x2 & SATA3 6Gb/s mode.

M.2 Armor

Good protection of the M.2 SSD is crucial for its lifespan and stable operation. ASRock provides a complete solution to protect your drive to keep it cool.

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

This motherboard features integrated USB 3.2 Gen2 Type-A and Type-C ports on the rear I/O panel to support next-generation USB 3.2 Gen2 devices with data transfer rates up to 10Gbps.

ULTRA STABLE POWER

+5V is transferred from +12V. This solution provides sufficient power to USB devices, without voltage drops directly from the power supply.

ANTISTATIC PROTECTION

Anti-static mouse and keyboard protection protects your hardware from lag and jams.

ULTIMATE SOUND PURITY

USB speakers connected to the Ultra USB Power port receive the cleanest signal, guaranteeing the highest quality HD sound, free of any interference.

2 OZ COPPER

57 grams of copper in the inner layers. The use of selected copper materials in the PCB layers enables operation at high temperatures and with high efficiency. Especially useful when overclocking.

PREMIUM 60A POWER CHOKES

ASRock's premium 60A power chokes provide three times the current saturation, stabilizing and boosting the Vcore voltage delivered to the motherboard.

STEEL PCI-E SLOTS

Professional Steel PCI-E Slots with a solid cover prevent signal interference between graphics cards. They also provide the ability to securely install heavy graphics cards.

AMD StoreMI technology

A powerful tool that combines the speed of an SSD and the capacity of your hard drive into one fast and manageable drive. SSDs are fast but expensive; they also offer a small capacity. Disk drives have a lot of memory for a low price, but they are much slower than SSDs. AMD StoreMI technology “combines” these two types of data stores into one drive. It automatically moves the data you use most to SSD, so you get the benefits of both worlds: SSD responsiveness and platter capacity.

Aluminum Radiator XX

The huge aluminum heatsink is very efficient at dissipating heat from the chipset and MOSFET transistors, keeping your PC stable.

Premium 60A power choke

Compared to traditional chokes, ASRock's new power chokes effectively increase (up to three times) the saturation current by delivering enhanced and improved CPU voltage to the motherboard.

Nichicon 12K Black capacitors

Premium 12K black capacitors with a lifespan of at least 12,000 hours. Compared to competing high-end motherboards that have 10,000 hours of capacitor life, ASRock's Nichicon 12K Black Caps solution offers 20% longer hardware lifespan and provides higher stability and reliability.

I/O Port Protection

A newly designed cover to protect the important I/O ports on the back panel of the motherboard ensures that they are not easily damaged by static electricity.

Sapphire Black PCB

Pure Black PCB. The new Sapphire Black PCB represents extreme stability and gives the board a mysterious feel.

High Density Glass Fiber PCB

The printed circuit board made of high-density glass fiber reduces the size of the gaps between the PCB layers, which protects the motherboard from power surges.

2 ounces of copper

Using only carefully selected copper components for the PCB layers, the 2oz Copper PCB provides lower operating temperatures and greater power efficiency when overclocking.

Full Spike Protection

Some delicate digital components on the motherboard are sensitive to overvoltages, and higher currents can cause your system to fail instantly. ASRock Full Spike Protection includes various technologies to protect motherboard components from being damaged by these unexpected power surges.
