RULE YOUR OWN LIGHTING WAY - POLYCHROME RGB
Steel legend motherboards deliver stunning performance and superior aesthetics to rule your own colorful lighting way! ASRock offers a very comprehensive control to perform the built-in RGB LEDs or the connected LED strips, CPU fans, coolers, chassis and any RGB devices smoothly. Devices can be synchronized across the Polychrome RGB Sync-certified accessories as well.
Dual M.2 For SSD
Two of the world's fastest M.2 slots. One delivers up to PCIe Gen3 x4 32Gb/s transfer speed, the other one supports SATA3 6Gb/s mode.
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.
PREMIUM 60A POWER CHOKE
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.
PCI-E STEEL SLOT
The advanced PCI-E Steel Slot packed with solid cover that prevent any signal interference with graphics cards. It also ensures the heavy graphics cards to be well-installed in the PCI-E slot safely.
XXL Aluminum Alloy Heatsink
Extra large aluminum alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable.
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.
Nichicon 12K Black Caps
Supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Black Caps that offer 20% longer lifespans and provide more stability and reliability.
I/O Armor
A new designed protective cover for all of the crucial parts near the motherboard's rear I/O, so that they won't easily be damaged by static electricity.
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.
