ASUS ROG Crosshair X870E Hero AM5 ATX Motherboard – DDR5 up to 8200+ (OC), Dual PCIe 5.0 x16, Wi-Fi 7 + BT 5.4, 5GbE + 2.5GbE LAN, 5x M.2 (3x PCIe 5.0), Dual USB4, Polymo Lighting II | 90MB1IE0-M0EAY0

Extreme Power & Performance

Ready for Advanced AI PC workloads, the Crosshair X870E Hero features 18+2+2 power stages rated at 110A for the VCORE and SOC rails with dual ProCool II connectors, MicroFine alloy chokes and premium 10K black metallic capacitors. ROG overclocking technologies include Dynamic OC Switcher — automatically switching between manual overclocking for heavy multithreaded workloads and Precision Boost Overdrive for single-threaded tasks, with Overclocking Load Guard preventing crashes — plus Core Flex for creative clock, power and thermal control, Asynchronous Clock with a built-in clock generator isolating CPU base clock from memory, PCIe and Infinity Fabric, and PBO Enhancement for aggressively tuned AMD performance.

ASUS AI Intelligence

AI Cache Boost supercharges large language model workflows — exclusive to ASUS AMD 800 and 600 series motherboards with Ryzen 9000 Series CPUs, optimizing CPU cache and memory pathways for up to 29% faster local LLM performance. AI Advisor answers natural-language questions about your hardware, AI Overclocking profiles the CPU and cooling, AI Cooling II balances thermals and acoustics with one click, and AI Networking II unleashes the full speed of Wi-Fi 7.

DDR5 Domination

Improved signal routing drives enthusiast-grade kits well beyond the 8 GT/s mark — up to 8200+ MT/s (OC) with Ryzen 9000, 8600+ (OC) with Ryzen 8000, and 8000+ (OC) with Ryzen 7000 Series processors. NitroPath DRAM Technology raises frequency up to 400 MT/s higher with 57% stronger slot retention force, while DIMM Fit precisely analyzes individual memory modules, DIMM Fit Pro provides advanced customization, and AEMP unlocks PMIC-restricted kits — with full AMD EXPO support.

Extensive PCIe 5.0 & Storage

Fully embracing the new standard with abundant Gen 5 support: two PCIe 5.0 x16 SafeSlots with PCIe Slot Q-Release Slim handle next-generation graphics cards, while five M.2 slots — three onboard PCIe 5.0 x4 and two PCIe 4.0 x4 — all with substantial cooling solutions, plus a SlimSAS connector with PCIe 4.0 x4 support and four SATA 6Gb/s ports with AMD RAIDXpert2 RAID.

Hyperspeed Connectivity — Dual USB4 & Dual LAN

Two USB4 Type-C ports blaze at 40Gbps each with DisplayPort output, joined by eight USB 10Gbps ports (six Type-A, two Type-C) on the rear panel. Front-panel connectors include two USB 20Gbps Type-C headers — one with Quick Charge 4+ up to 60W fast charging and USB Wattage Watcher. Networking is dual: Intel 2.5Gb Ethernet plus Realtek 5GbE LAN with LANGuard, while Wi-Fi 7 (Qualcomm QCNCM865 or MediaTek MT7927 by module) with the ASUS Q-Antenna and Bluetooth 5.4 covers wireless.

SupremeFX Audio, Polymo Lighting II & EZ DIY

ROG SupremeFX ALC4082 7.1 audio with an ESS ES9219 Quad DAC, 120dB SNR, gold-plated jacks and optical S/PDIF delivers reference sound with Dolby Atmos. Dark hues with premium metallic textures, nickel-plated surfaces and a stereoscopic M.2 and chipset heatsink are crowned by Polymo Lighting II — an upgraded lighting module in the I/O shroud providing more dynamic RGB illumination for the signature ROG logo. A metal backplate reinforces the board, and the full Extreme OC Kit (FlexKey, ReTry, start button, LN2 mode) plus Q-Design (Q-Release Slim, M.2 Q-Release/Q-Slide/Q-Latch, Q-Code, Q-Dashboard, BIOS FlashBack, Clear CMOS, pre-mounted I/O shield) makes building effortless.
