Optimized VRM Design

12+1+1+1+1 Power Phase Design
Featuring sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.
SPS (Smart Power Stage)
Dr.MOS design features the latest SPS (Smart Power Stage) technology. It’s optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.
Hi-Density Power Connector
CPU overclocking requires higher current. ASRock Hi-Density Power Connectors are designed to withstand higher currents compared to traditional CPU and ATX power connectors, providing a more stable system and reducing the risk of fire during heavy overclocking.
Exclusive 20K Cap with 1000uF Capacitance
The upgraded 20K Black capacitor not only extends the lifespan to 20,000 hours but also increases the capacitance value from 560uF to 1000uF, bringing several benefits:

●Higher Capacitance: Greater charge storage for better support under high loads.
●Lower Ripple: Reduced power output fluctuations, improving quality.
●More Stable Output Current: Stable power supply, minimizing voltage impacts.
●Better Performance & System Stability: Increased reliability and consistent performance.

2oz Copper PCB

2 ounce copper inner layers that provide stable signal traces and power shapes! Delivering lower temperature and higher energy efficiency for overclocking.

Extreme Memory Overclocking

Derived from the “built for stable and reliable” designing concept, ASRock does not compromise on any details. This motherboard is built with high quality materials, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance by enabling the pre-tested profiles. Make sure the memory modules are Intel® XMP/AMD EXPO™ capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all.

* There are certain risks involved with memory overclocking and may affect your system’s stability. Please realize that overclocking should be done at your own risk and expense. EXPO/XMP profile support may vary by different system configuration, memory modules and motherboard models. Please refer to Memory QVL for the completed support list.
