AM5 platform for Ryzen 7000, 8000 and 9000 series

The ROG Crosshair X870E Dark Hero is an ATX motherboard built for AMD Ryzen 7000, 8000 and 9000 series processors. It targets enthusiasts who need a high-end foundation for gaming, content creation and AI workloads. The board delivers extensive connectivity and robust power delivery in a dark-themed design.

Sustained load behaviour with 20+2+2 power stages

A 20+2+2 phase design rated at 110 A per stage feeds the CPU through ProCool II connectors, MicroFine alloy chokes and premium metallic capacitors. Massive heatsinks integrated with the I/O cover join an L-shaped heatpipe and high-conductivity thermal pads to keep VRM temperatures controlled during prolonged heavy workloads. AI Cooling II adjusts fan curves in real time to maintain thermal headroom.

Five M.2 slots with a 3D vapour-chamber heatsink

The board provides five M.2 slots: two PCIe 5.0 x4 slots supporting 2242, 2260, 2280 and 22110 drives, plus three PCIe 4.0 slots. A 3D vapour-chamber heatsink covers the primary PCIe 5.0 slot while substantial heatsinks cool the remaining four, preserving peak SSD throughput under continuous data transfers.

Questions about this item

How hot does the 20+2+2 110A power-stage design run when the system is under sustained all-day load?

Massive heatsinks integrated with the I/O cover are joined by an L-shaped heatpipe and connected to the power stages with high-conductivity thermal pads to dissipate heat from the 20+2+2 110A power stages during extended operation.

Which DDR5 memory kit must I already own to reach the rated 9600 MT/s overclocked speed on this board?

A 4x288-pin DDR5 kit rated for AMD EXPO at 9600 MT/s or higher is required to hit the maximum overclocked frequency supported with Ryzen 8000 Series processors.

Will my existing PCIe 4.0 graphics card run at full x16 bandwidth in the primary PCIe 5.0 x16 SafeSlot?

Yes, a PCIe 4.0 graphics card will operate at x16 electrical speed in the primary PCIe 5.0 x16 slot when a Ryzen 9000 or 7000 Series processor is installed.
