ROG Crosshair X870E Hero BTF

The ROG Crosshair X870E Hero BTF features hidden connectors for motherboard and GPU power, USB, and fan cables, delivering an ultra-clean look for your AMD Ryzen™ 9000 build. It pairs robust power delivery with ASUS-exclusive AI-enhanced tuning, PCIe® 5.0, and DDR5 slots with NitroPath DRAM Technology for advanced memory performance. Plus, Polymo Lighting II adds striking visual flair to your rig.

Advanced BTF Design

With the combination of a BTF graphics card, motherboard and chassis, you can enjoy a full hidden-connector experience. This Advanced BTF approach is achieved through the new graphics card high-power slot available on BTF motherboards, which can deliver up to 600 watts to BTF graphics cards. With a full set of BTF components, builders can eliminate visible cables for an extra-clean aesthetic.

Hidden-Connector Design

The hidden-connector design can be ideal for first-time builders, because it provides easier cable management. The absence of visible cables also creates a clean and tidy look that would normally require an expert.

Graphics Card High-Power Slot

The graphics card high-power slot stands ready to supply all the wattage that a BTF graphics card needs. This special design can deliver up to 600 watts through the motherboard itself, eliminating the need for visible 8-pin or 16-pin power cables on the front.

ASUS AI Intelligence

AI Cache Boost

Supercharge your large language model (LLM) workflows with AI CACHE BOOST. Exclusive to ASUS AMD 800 and 600 series motherboards that use Ryzen™ 9000 Series CPUs, this BIOS setting optimises CPU cache and memory pathways to deliver up to 29% faster local LLM performance with high-speed memory tuning.

• Increase AI LLM performance up to 29% with AI Cache Boost

Tokens Per Second

With an ASUS AMD 600 or 800 series motherboard and a Ryzen™ 9000 series CPU, you can enable the AI Cache Boost setting in the BIOS. This feature applies comprehensive optimisations to CPU cache and memory pathways, greatly reducing the typical performance drop that can happen when VRAM is used up.

Internal testing determined that enabling AI Cache Boost delivered up to a 15% performance uplift when running large language models that exceeded graphics card memory. With high-speed DDR5 memory and additional Infinity Fabric clock (FLCK) speed tuning, this performance uplift nearly doubled.

For enthusiasts, creators or anyone who wants a powerful AI model capable of deep reasoning and natural conversation running on their own hardware, they can enjoy these uplifts today with AI Cache Boost.

ASUS AI Advisor

Using AI technology to understand natural-language questions or scenario descriptions, ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way.

ASUS AI Advisor is an ASUS technical expert that's always available to answer your questions. Owners of compatible ASUS motherboards can interact with this AI-powered technology using natural language to learn more about their hardware. For DIY beginners, it can provide easy-to-understand explanations of one-click optimisation features like AI Overclocking and fan speed tuning, and for seasoned PC-building veterans, it can offer guidance and instructions on the latest features offered by ASUS.

* Availability of ASUS AI Advisor may vary by region.

AI Overclocking

Tuning is now faster and smarter than ever before.

ASUS AI Overclocking profiles the CPU and cooling to predict the optimal configuration and push the system to its limits. Predicted values can be engaged automatically or used as a launching ground for further experimentation.

AI Cooling II

Balance the thermals and acoustics of any build with a single click.

A proprietary ASUS algorithm slashes unnecessary noise while running a quick stress test, and then monitors CPU temperatures to dynamically adjust fans to optimal speeds.

AI Networking II

AI Networking II combines intelligent technologies to continuously optimise network performance, provide trustworthy and seamless connectivity, and unleash the full speed of WiFi 7 (Features may vary by model.).

Traffic Monitor

Armoury Crate's Traffic Monitor tracks your current WiFi channel usage. Move to a less congested channel by clicking the “Channel Switch” button (The "Channel Switch" function requires pairing with an ASUS router. If not paired with an ASUS router, the channel change process can be performed in the "Router IP" section of the Traffic Monitor.) for improved network performance.

Fast Check

Armoury Crate’s Fast Check empowers users to rapidly detect WiFi signal strength.
