Optimized VRM Design

Dr. MOS is an integrated power stage solution designed specifically for synchronous buck-set down voltage applications!

Compared to traditional discrete MOSFETs, it intelligently delivers a higher current for each phase, thus providing an improved thermal result and superior performance.

Featuring sturdy components and completely smooth power delivery to the CPU, it offers enhanced performance for gamers.

The 6-Layer PCB provides stable signal traces and power shapes for memory overclocking, resulting in lower temperatures and higher energy efficiency!

Thus, it's able to support the latest memory modules with the most extreme memory performance!

PCIe 5.0 and Surface-Mount Tech

Compared to the conventional DIP-style PCIe slot, the SMT type PCIe slot improves signal flow and maximizes stability under high speed—a key breakthrough to fully support the lightning speed of the latest PCIe 5.0 standard.

The latest PCI Express 5.0 is capable of a breathtaking bandwidth of 128 GBps, ready to unleash the full potential of future high-end graphics cards.

Nahimic Audio

Whether you are using headphones, a headset, external or internal speakers, via USB, Wi-Fi, analog output, or even HDMI, Nahimic Audio offers you the most engaging listening experience, vibrant and rich with details.

POLYCHROME RGB

In addition to the built-in RGB illumination, it also features onboard RGB headers and an addressable RGB header that allow the motherboard to be connected to compatible LED devices such as strips, CPU fans, coolers, chassis, and so on.

Users can also use the Polychrome RGB Sync-certified accessories to synchronize RGB LED devices to create their own unique lighting effects.

High-Speed M.2 Solution

This motherboard can support multiple M.2 storage devices, one of which can support PCI Express 4.0 M.2 SSDs, and it can perform at twice the speed of previous 3rd generation motherboards, providing a lightning-fast data transfer experience.

Dragon 2.5 Gb/s LAN

The intelligent 2.5 Gb/s LAN platform is built for maximum networking performance to meet the demanding requirements of home networking, content creators, online gamers, and high-quality streaming media.

Boost networking performance up to 2.5X the bandwidth compared to the standard gigabit Ethernet, and you’ll enjoy a faster and uncompromised connectivity experience for gaming, file transfers, and backups.

USB 3.2 Gen2x2 Type-C

The latest USB 3.2 Gen2x2 Type-C delivers up to 20 Gbps of data transfer rate, which is twice as fast as the previous generation, providing a blazing fast data transfer interface with a reversible USB Type-C design that fits the connector either way.

BIOS Flashback

Get the most convenient BIOS flashing with just a simple click. Users can easily achieve the latest BIOS support with a USB and power supply; no CPU, RAM, or other components are required.

M.2 (Key E) for WiFi Besides the onboard LAN port, users may also choose 802.11ac wireless connections through the M.2 (Key E) slot.
