Product Description
The ASUS ROG CROSSHAIR X870E DARK HERO is an enthusiast-class ATX gaming motherboard engineered to deliver maximum performance, rock-solid power delivery, and next-generation connectivity for AMD Ryzen 9000, 8000, and 7000 Series desktop processors on the AM5 socket. Designed in a stealth all-black aesthetic featuring customizable Polymo Lighting II micro-patterns across the I/O cover, this board merges enthusiast-grade hardware engineering with intelligent ASUS AI performance profiling.
Sustained heavy computing and extreme processor overclocking are powered by a 20(110A)+2(110A)+2(80A) teamed power-stage VRM architecture fed by dual ProCool II 8-pin power connectors. Thermal dissipation is achieved through an interconnected heatsink assembly combining extruded aluminum blocks, direct-contact thermal pads, full-coverage M.2 backplates, and a dedicated 3D vapor-chamber heatsink over the primary PCIe 5.0 slot. With 4 DDR5 DIMM slots featuring NitroPath DRAM technology and server-grade trace optimizations, the platform supports up to 256 GB of system memory at overclocked frequencies exceeding 9600+ MT/s via AMD EXPO.
Next-generation graphics and storage expansion are led by two PCIe 5.0 x16 SafeSlots equipped with the PCIe Slot Q-Release Slim tool-free card release system. Storage options include five onboard M.2 slots—two wired for PCIe 5.0 x4 bandwidth and three operating over PCIe 4.0—alongside four SATA 6Gb/s ports for extensive high-speed NVMe and mass-storage configurations.
The board features high-speed dual wired networking with a Realtek 10-Gigabit Ethernet port paired with a Realtek 5-Gigabit Ethernet controller, complemented by native Wi-Fi 7 (802.11be) delivering 320 MHz channel support and up to 6.5 Gbps theoretical wireless speeds. External I/O is headlined by dual USB4 40Gbps Type-C ports capable of driving 8K visual displays, while the front panel supports two USB 20Gbps Type-C connectors, including one capable of up to 60W Quick Charge 4+ with live USB Wattage Watcher hardware monitoring. Accompanied by the ROG SupremeFX ALC4082 codec paired with an ESS ES9219 QUAD DAC and supported by a 3-year warranty, the ROG CROSSHAIR X870E DARK HERO provides a comprehensive foundation for high-end gaming and content creation systems.
