The Sound Tracker is a visual indicator that points out the directions from which predominant sounds are coming. Each sound is properly positioned in 360° on a radar for a full immersion during the game.
Dr. MOS
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus providing improved thermal result and superior performance.
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.
14 Power Phase Design
Featuring 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.
Hi-Density Power Connector
Reduces 23% power loss and decreases the connector’s temperature by 22 degrees Celsius.
8+4 12V Power Connectors
24-pin ATX Power Connector
2oz Copper PCB
2 ounce copper inner layers that provide stable signal traces and power shapes! Delivering lower temperature and higher energy efficiency for overclocking, it's able to support the latest DDR4 memory modules with most extreme memory performance!
Automatically detects and accelerates game traffic ahead of other network traffic for smoother, stutter-free in-game performance and the competitive edge.
Front USB 3.2 Gen1 Type-C
Front USB 3.2 Gen1 Type-C header delivers up to 5 Gbps data transfer rate and next generation reversible USB design to the front panel of computer case.
M.2 (KEY E) For WiFi
Besides the onboard LAN port, users may also choose 802.11ac wireless connections by M.2 (Key E) slot.
*Wi-Fi module is not included.
Flexible Integrated I/O Shield
Unlike most so called pre-mounted I/O shield that is only decorated with fancy color schemes. We reserve more tolerance space and allow IO shield is adjustable when installing, thus fitting chassis perfectly without any mechanical issue.
Dual Graphics Outputs
Complete with two types of most used connectors! Packed with a HDMI + DisplayPort combo, you have more graphics output options now.
Gold Audio Jacks
Everything will wear off in time, but gold looks better! Gold audio jack provides stable sound transmission!
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.
Live Update & APP Shop
ASRock Live Update & APP Shop is designed for your convenience. We provide various apps and support software for users to download. You can also easily optimize your system and keep your motherboard up to date with ASRock Live Update & APP Shop.
