Power stability and construction

Digi Power, with its carefully selected components and massive heatsinks, keeps the platform running smoothly even under sustained load, while the multi-layer copper PCB helps with efficient heat dissipation and clean signal routing. The reinforced Steel Slot protects the graphics connector from mechanical stress and reliably supports heavier cards.

Storage, connectivity and software

The board is ready for fast NVMe SSDs, including the PCI Express 4.0 interface, and offers flexible peripheral connectivity via USB, including a Type-C on the rear panel. The trio of video outputs makes it easy to connect multiple monitors (requires an APU), networking is provided by a gigabit controller, and startup diagnostics are made easy with the Post Status Checker. System management is complemented by a useful suite of tools and synchronisable Polychrome RGB lighting.

Easy assembly, protection and customisation

The Post Status Checker makes it easy to find the cause of a failed startup thanks to clear CPU/DRAM/VGA/BOOT status indicators, while Full Spike Protection shields the interfaces from voltage spikes. The steel-reinforced Steel Slot increases the mechanical durability of the PCIe connector for the safe installation of heavier cards. The ready-to-use M.2 Key E slot lets you add wireless connectivity as needed, the RGB and addressable ARGB headers can be plugged into the Polychrome RGB ecosystem, and you can keep the firmware and tools up to date via the Live Update & APP Shop.
