This motherboard features onboard RGB headers and an addressable RGB header that allows the motherboard to be connected to compatible LED devices such as individual strips, CPU fans, coolers, chassis and so on. Users may also synchronize their RGB LED devices across the Polychrome RGB Sync-certified series of accessories to create their own unique lighting effects.

The addressable RGB LED header supports the WS2812B addressable RGB LED strip (5V/Data/GND) with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters.
The RGB LED header supports a standard 5050 RGB LED strip (12V/G/R/B) with a maximum power rating of 3A (12V) and length within 2 meters.
An easy troubleshooting tool that shows the CPU, DRAM, GPU and boot operation every time you start up the system. Post Status Checker is a fast and easy way to identify the source of any problems.
Dual M.2 SSD Support for Type 22110 M.2
These motherboards are ready for higher capacities and even faster Type 22110 M.2 NVMe SSDs to fulfill any performance need. Two Ultra M.2 sockets, that support both SATA3 6Gb/s and PCIe Gen3 x4 modes, push data transfer speeds up to 32Gb/s. These sockets are compatible with ASRock's U.2 Kit for installing some of the world's fastest U.2 PCIe Gen3 x4 SSDs.
M.2 Armors
Good M.2 SSD protection is important for longevity and stability. ASRock provides a complete M.2 armor solution on the B365 platform that makes SSDs efficiently run at low temperatures.
This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear I/O that support next-generation USB 3.1 Gen2 devices and deliver up to 10Gbps data-transfer rates.
USB 3.1 Gen2 doubles the data transfer rate!

Stable & Reliable
Intel® LAN provides the best throughput performance, lower CPU utilization and enhanced stability that, all together, delivers the ultimate network experience for users!
Supports Intel® Optane™ memory technology and Intel® Optane™ storage technology that redefines a new standard of high performance and responsiveness.
Extra-large aluminum-alloy heat sinks effectively take away heat from the MOSFET and chipset so that your whole system may perform more stably.
Compared to traditional chokes, ASRock's premium 50A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
This motherboard series houses supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other 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.
A newly designed protective cover for all of the crucial parts near the motherboard's rear I/O have been implemented to prevent damage from static electricity.
A new, mysterious matte black and copper color scheme has been added to match the prestigious components on ASRock's high-end motherboards.
The High Density Glass Fabric PCB design reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
Besides the onboard LAN port, users may also choose 802.11ac wireless connections by the M.2 (Key E) slot.
Wi-Fi module is not included.
The ASRock Live Update & APP Shop has been designed to meet 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 this included software.
