Unmatched processing power and future compatibility.

The first step towards building a supercomputer starts with the processor, which is why this board comes equipped with a socketLGA 1851, making it fully ready to embrace the new generation of processorsIntel Core Ultra (Series 2). Supported by the Intel B860 chipset, the board ensures you make the most of every drop of processor power through advanced Turbo Boost technologies, providing instant responsiveness in the most complex tasks.

Revolution in Random Access Memory: Speeds that Break Barriers

Data transfer speed limits will no longer be a barrier for you. The board supports two slots for fifth-generationDDR5memory with a capacity of up to 128 GB. But the real advantage lies in its ability to overclock to frequencies exceeding8800 MHz (MT/s). Thanks to ASUS Enhanced Memory Profile III (AEMPIII) technology, you will achieve exceptional performance with complete smoothness, which directly reflects on system responsiveness and multitasking.

Ultra-fast storage and advanced graphics expansion

Time is your most valuable asset, which is why ASUS has provided storage speeds that take you into the future. The board comes with a primaryM.2 slot that supports PCIe 5.0 x4, opening the door to the next generation of ultra-fast storage drives, in addition to a second M.2 slot and four SATA ports to meet all your storage needs. To ensure flawless graphics performance, the board is equipped with aPCIe 4.0 x16slot to efficiently accommodate the latest graphics cards.

Network connectivity and data transfer that keeps up with the times

The board does not overlook the importance of fast connectivity, as it offers a network portRealtek 2.5Gb EthernetEnhanced with ASUS LANGuard technology to protect and ensure the stability of the connection, making it an ideal choice for transferring large files and online gaming with near-zero latency. On the external connectivity front, the motherboard offers a arsenal of USB ports, topped by aUSB 10Gbpshigh-speed port on the rear panel, and support for a USB Type-C port on the front of the computer for maximum convenience.

An engineering design focused on durability and cooling

Powerful performance requires superior protection; therefore, the motherboard comes equipped with aASUS 5X PROTECTION III, which includes a DIGI+ VRM power system to ensure current stability, protection from electrical fluctuations, and an enhanced SafeSlot Core+ slot to support heavy graphics cards. The voltage regulation modules (VRM) are also equipped with carefully designed heat sinks to efficiently dissipate heat, ensuring stable performance even under prolonged stress.

An immersive audio and visual experience

The power of the motherboard is not limited to pure technical performance but extends to the sensory experience. With the surround sound chipRealtek 7.1and premium Japanese audio capacitors, you will enjoy stunning audio quality up to 24-Bit/192 kHz, with dedicated isolation layers on the printed circuit board to prevent any electromagnetic interference. For fans of visual customization, theAura Syncsystem offers the ability to connect and synchronize RGB lighting with other computer components to create a complete artistic masterpiece.
