Performance components and power
The board uses an optimised VRM with a 14+1+1+1+1 phase design, ensuring a stable power supply to the processor. Integrated Dr.MOS modules are an advanced solution delivering higher current to each phase, which results in better thermal properties and higher performance. A dual-layer PCB with 2oz copper layers provides stable signal traces and ensures lower temperatures when overclocking. High-quality 20K capacitors guarantee long-term system reliability. Support for DDR5 XMP and EXPO profiles lets you use pre-tested profiles and achieve maximum memory performance.
Cooling and thermal management
The intelligent cooling system uses optimised aluminium heatsinks that efficiently dissipate heat during demanding tasks. The extra-large aluminium M.2 heatsink effectively improves heat dissipation from high-speed M.2 SSDs, ensuring system stability. The M.2 backplate heatsink efficiently dissipates heat through the motherboard's PCB. The board is equipped with a screwless multi-layer M.2 heatsink featuring a Toolless Design and an extended latch for easy graphics card installation. A temperature sensor with a cable offers an additional source for temperature monitoring.
Connectivity and expandability
The board provides comprehensive connectivity thanks to Wi-Fi 6E 802.11ax technology, which extends the spectrum into the new 6GHz band. The Thunderbolt 4/USB4 Type-C port offers fast data transfers of up to 40Gb/s and lets you connect external monitors and devices with a single cable. The intelligent 2.5G LAN platform increases bandwidth up to 2.5× compared to standard gigabit ethernet. Ultra USB Power transforms the 5V supply from the +12V line to provide stable power. The front USB 3.2 Gen2x2 Type-C connector offers transfer speeds of up to 20Gb/s. High-quality sound is delivered by the Realtek ALC1220 codec with seven-channel HD Audio and Nahimic Audio technology.
