Refurbished ASUS ROG CROSSHAIR X870E DARK HERO AM5 DDR5 PCIe 5.0 ATX Motherboard

Aim Precise. Deliver With Strength.

Clad in a sleek, understated black design, the ROG Crosshair X870E Dark Hero delivers refined performance for high-end builds, anchored by a 20(110A)+2(110A)+2(80A) power stage design, support for high-speed DDR5 memory, and PCIe® 5.0 connectivity. Storage is covered by five onboard M.2 SSD slots with heatsinks, including a 3D VC M.2 heatsink for advanced thermal performance, while Realtek 10G Ethernet and dual USB4® ports handle next-generation connectivity. ASUS-exclusive AI technologies and Polymo Lighting II round out the platform, pairing intelligent tuning with a clean, premium aesthetic.

ASUS AI Intelligence

ASUS AI Intelligence on the ROG Crosshair X870E Dark Hero brings smarter system control across performance, thermals, and connectivity. AI Cache Boost, exclusive to ASUS AMD 800 and 600 series boards paired with Ryzen™ 9000 Series CPUs, tunes CPU cache and memory pathways at the BIOS level, delivering up to 29% faster local LLM performance. ASUS AI Advisor adds an in-system guide that understands natural-language questions. AI Overclocking accelerates CPU tuning with automated adjustments, while AI Cooling II balances fan curves for efficient thermal control and lower noise. AI Networking II continuously manages bandwidth and latency, unlocking the full speed of WiFi 7* where supported.

20+2+2 Power Stages & Hardcore Overclocking

Built for serious overclocking, the ROG Crosshair X870E Dark Hero gives you deep control over CPU behaviour at every load state. Dynamic OC Switcher lets you define current and temperature thresholds to automatically shift between a manual overclock for multithreaded workloads and Precision Boost Overdrive for single-threaded tasks, with Overclocking Load Guard adding enhanced instantaneous current protection. Core Flex opens up advanced control over clocks, power, and thermals, while the onboard asynchronous clock generator isolates CPU base clock from memory, PCIe, and Infinity Fabric. PBO Enhancement further extends AMD Precision Boost Overdrive by pushing current and voltage budgets when thermal and power conditions allow.

DDR5 Memory Speeds Beyond 8600+ MT/s

Memory tuning on the ROG Crosshair X870E Dark Hero is built to push DDR5 well past stock limits. Server-grade DRAM enhancement and refined signal routing allow enthusiast kits to scale beyond 9 GT/s*, with official support for memory overclocking up to 8600+ MT/s. DIMM Fit and DIMM Fit Pro add BIOS-level analysis and tuning, intelligently evaluating modules to improve stability while offering advanced manual control. NitroPath DRAM Technology further boosts headroom, enabling frequencies up to 400 MT/s higher and increasing slot retention force by 57%. AEMP (ASUS Enhanced Memory Profile) rounds out the stack with automatic performance profiles for PMIC-restricted memory modules.

Dynamic OC and Core Flex Control

Dynamic OC Switcher, Core Flex, asynchronous clock generator, and PBO Enhancement give extreme control over clocks, power, and thermals, enabling granular performance scaling and safer overclocking for every workload.

Five M.2 Slots with 3D Heatsinks

Cooling on the ROG Crosshair X870E Dark Hero is built to handle sustained high-end workloads. Comprehensive thermal management pulls data from multiple onboard temperature sources and feeds it into 4-pin fan headers, allowing fine-grained control across air and liquid cooling setups. Storage thermals are equally well covered, with a dedicated 3D VC M.2 heatsink delivering advanced heat dissipation for high-speed PCIe SSDs.

ASMedia ASM1162 Controller – Extra SATA Connectivity

The ROG Crosshair X870E Dark Hero comes with a pre-installed ASMedia ASM1162 controller, providing two additional SATA 6Gb/s ports. This expands storage flexibility for extra SSDs or HDDs, giving users more options for mass storage or legacy drives without relying solely on the motherboard’s native SATA channels.

10G + 2.5G, Dual USB4®, WiFi 7 Ready

Realtek 10G Ethernet, 2.5G Ethernet and dual USB4® ports handle next-generation connectivity, while AI Networking II optimizes WiFi 7 bandwidth automatically for minimal latency during gaming and streaming.

Advanced Thermal Management and Fan Control

Multiple temperature sensors feed 4-pin fan headers for complete airflow control, while AI Cooling II balances thermals and noise across the system.

AIO Q-Connector for Effortless Liquid Cooling

The board supports the AIO Q-Connector when paired with an ROG Strix LC IV series AIO CPU liquid cooler. The Q-Connector delivers power and control for the pump, ARGB lighting, and—on select models—the integrated display, while radiator fan PWM signals are routed internally through the tube sleeving, reducing cable clutter and improving airflow.

64MB BIOS for Extended CPU Support

The ROG UEFI (BIOS) delivers a full-featured tuning environment. A 64MB BIOS chip expands the interface and supports broader CPU compatibility across current and future AM5 processors. BIOS Q-Dashboard adds a visual layout of hardware connections mapped directly to settings, cutting down setup time and removing guesswork.

DriverHub, Dolby Atmos, GlideX, Monitoring Tools

ASUS DriverHub handles driver and utility installation, automatically detecting versions and supporting one-click updates. Audio is handled by Dolby Atmos for immersive 3D sound. ASUS GlideX extends your desktop across devices, while HWiNFO and AIDA64 Extreme provide detailed system monitoring. MB Manager centralises control over key motherboard features.

Glow Up Your Game with Aura Sync

Up your game with complementary Aura Sync enhanced aesthetics, featuring preset lighting effects that can be easily synchronized across compatible ROG graphics cards, monitors, keyboards, and mice to give your setup a unified look.
