The 8-phase Digi Power design with premium 50A power chokes provides stable power delivery to the CPU, supporting overclocking capabilities while maintaining lower temperatures. The 2oz copper PCB construction ensures stable signal traces and improved energy efficiency for demanding applications. The motherboard supports DDR4 memory up to 4733+ MHz (OC) across four DIMM slots with a maximum capacity of 128GB.

Connectivity and Expansion

Equipped with PCIe 4.0 x16 slot for graphics cards, this motherboard supports AMD CrossFireX multi-GPU configurations. The Hyper M.2 socket delivers PCIe Gen4 x4 speeds for next-generation NVMe SSDs, capable of twice the speed of PCIe 3.0. Additional expansion includes two PCIe 3.0 x1 slots and four SATA3 6.0 Gb/s connectors with RAID support (RAID 0, 1, and 10).

Audio and Networking

The Realtek ALC1200 audio codec provides 7.1 channel HD audio with Nahimic Audio technology for enhanced gaming and multimedia experiences. Gigabit Ethernet LAN (Realtek RTL8111H) includes Wake-On-LAN support and Energy Efficient Ethernet 802.3az compliance. The motherboard features PCB isolate shielding and individual PCB layers for left/right audio channels to minimize interference.

Features and Compatibility

Windows 11 ready with HDMI 2.1 output supporting 4K resolution at 60Hz, HDR, and HDCP 2.3. The POST Status Checker provides quick troubleshooting by displaying CPU, DRAM, VGA, and BOOT operation status during startup. ASRock Full Spike Protection safeguards all USB, audio, and LAN ports. The XXL aluminum alloy heatsink keeps critical components cool during extended gaming sessions.

I/O and Cooling

Rear panel includes six USB 3.2 Gen1 ports, PS/2 port, HDMI output, Gigabit LAN, and HD audio jacks. Internal headers support two additional USB 3.2 Gen1 ports and four USB 2.0 ports. Smart fan control manages one CPU fan connector, one CPU/Water Pump fan connector, and four chassis/water pump fan connectors. RGB LED headers and addressable LED headers enable customizable lighting synchronization through ASRock Polychrome SYNC software.
