Product Description
The ASUS ROG CROSSHAIR X870E HERO is an enthusiast-tier ATX gaming motherboard engineered to maximize the processing, multitasking, and overclocking capabilities of AMD Ryzen 9000, 8000, and 7000 Series desktop processors on socket AM5. Finished in dark gunmetal tones and highlighted by customizable Polymo Lighting II RGB illumination across the I/O shroud, this board balances heavy hardware power delivery with ASUS AI tuning tools.
Power delivery is driven by an 18(110A)+2(110A)+2 power-stage VRM layout utilizing MicroFine alloy chokes, 10K black metallic capacitors, and dual ProCool II 8-pin inputs. Thermal management is handled by substantial aluminum VRM heatsinks joined by an integrated heatpipe, direct-contact thermal pads, full-coverage M.2 backplates, and a dedicated 3D vapor chamber heatsink on the primary M.2 slot. Memory overclocking is elevated by NitroPath DRAM Technology across 4 DDR5 DIMM slots, optimizing trace pathways to support up to 256 GB of memory at speeds up to 8600+ MT/s (OC) via AMD Extended Profiles for Overclocking (EXPO).
Expansion is anchored by two PCIe 5.0 x16 SafeSlots utilizing the PCIe Slot Q-Release Slim mechanism for tool-free graphics card swaps. Storage configurations accommodate up to five onboard M.2 slots (three operating at PCIe 5.0 x4 and two at PCIe 4.0 x4), one high-speed SlimSAS PCIe 4.0 x4 connector, and four SATA 6Gb/s ports.
Connectivity includes dual wired Ethernet (Realtek 5-Gigabit and Intel 2.5-Gigabit) and native Wi-Fi 7 (802.11be) with 320 MHz channel width for multi-gigabit throughput. The rear panel provides dual USB4 40Gbps Type-C ports supporting 4K display output, while internal front headers offer dual USB 20Gbps Type-C ports, including one configured for up to 60W Quick Charge 4+ with live USB Wattage Watcher hardware monitoring. Accompanied by the ROG SupremeFX ALC4082 audio codec paired with an ESS ES9219 QUAD DAC and supported by a 3-year warranty, the ROG CROSSHAIR X870E HERO provides a comprehensive platform for high-end gaming and creation rigs.
