An easy troubleshooting tool that shows the CPU / DRAM / VGA / BOOT operation every time you start up the system. Post Status Checker is an fast and easy way to identify the source of the problem.
Complete with two types of most used connectors! Packed with a HDMI + DisplayPort combo, you have more graphics output options now.
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.
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Intelligently delivering higher current and driving up to 50A continuous current for each phase, thus providing improved thermal result and superior performance.
Compared to traditional chokes, ASRock’s premium 90A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
A new mysterious matte black and copper color scheme to match the prestigious components on ASRock's high-end motherboards.
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
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.
Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately.
