This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear I/O to support next-generation USB 3.1 Gen2 devices while delivering up to 10 Gbps data-transfer rates.
USB 3.1 Gen2 doubles the data transfer rate!
USB 3.1 Gen2 Type-C doubles the charge speed!
ULTRA USB POWER
ULTRA STABLE POWER
The +5V voltage on these motherboards is transferred from the +12V, supplying enough current to USB devices without dropping voltage directly from the PSU.
ANTISTATIC SHIELD
Protect your mouse and keyboard against static electricity. This especially lowers the chances of USB mouse lag or stuttering.
PURE AUDIO QUALITY
The USB speaker is best connected via Ultra USB Power ports to execute a pure current while offering high audio quality without distortion.
2 oz Copper
This motherboard has been made with 2 ounces of copper inner layers. The copper materials for PCB layers were carefully selected to deliver lower temperatures 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 a solid cover prevents any signal interference with graphics cards. It also ensures that heavy graphics cards can be safely installed in the PCI-E slot.
XXL Aluminum-Alloy Heatsink
Extra-large, aluminum-alloy heat sinks effectively take away heat from the MOSFET and chipset so that your whole system may perform more stably.
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 newly designed protective cover for all of the crucial parts near the motherboard's rear I/O serve to protect the motherboard from damage by static electricity.
Sapphire Black PCB
The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.
High Density Glass Fabric PCB
The motherboard's High Density Glass Fabric PCB design 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, the 2oz Copper PCB delivers lower temperatures and higher energy efficiency for overclocking.
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.
