Why are our prices higher than BestBuy or NewEgg?
The prices are higher because we have to buy in small quantities straight from the distributors. We don't have the luxury of buying thousands of GPUs at a discounted rate like major retailers.
However, we currently only charge tax to eight states: CA, GA, WA, TX, IL, NJ, KS, and FL.
So depending on your location, our prices can actually be cheaper than major retailers if you're lucky enough to reside in those states by not paying online sales tax.
Upgraded power delivery, passive chipset cooling, and stealthy aesthetics allow the Crosshair VIII Dark Hero to strike from the shadows and form a menacing duo with AMD Zen 3.
ROG Crosshair VIII Dark Hero boasts an optimized power design layout and all the cooling headers you need to handle the prodigious power of the latest AMD Ryzen processors.
Teamed Power Architecture
Modern CPU architectures up the ante for motherboard power design by transitioning from deep power-saving modes to full load almost instantaneously. Our latest VRM architecture rises to the challenge by utilizing teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.
ASUS Optimem III
Infused with proprietary memory trace layout tweaks that improve signal integrity and mitigate noise, Optimem III allows memory kits to run at lower latencies, reduced voltages, and operate at higher frequencies. Stack the Dark Hero with your favorite modules and maximize Zen 3 processors throughput for applications that demand massive bandwidth, or balance infinity fabric and memory performance for a diverse range of workloads.
COOLINGMaintaining system stability is paramount under high load, so Crosshair VIII Dark Hero employs passive chipset cooling with large VRM and chipset heatsinks that strike the right balance between surface area and mass. Featuring premium components and multiple fan headers, Crosshair VIII Dark Hero is fully armed to provide the best foundation for gaming systems.
- VRM heatsink - The two VRM heatsinks are placed above the MOSFETs and chokes, and are connected by a heat-pipe to further increase surface area for heat dissipation.
- M.2 heatsink - Two dedicated heatsinks keep the dual M.2 SSDs at the optimum operating temperature for consistent performance and reliability.
- High-conductivity thermal pad - A high-quality thermal pad improves overall heat transfer from the system by bridging the heat generated by the power stages to the heatsink.
- Passive chipset heatsink - A dedicated chipset heatsink draws heat away to maintain optimum operating temperatures.
ROG Crosshair VIII Dark Hero features the most comprehensive cooling options ever.
- Multiple temperature sources - Each header can be set to monitor and react to three user-configurable thermal sensors for workload-based cooling. All settings can be easily managed by Fan Xpert 4 or UEFI.
- 4-pin PWM/DC fan - Every onboard header supports auto-detection of PWM or DC fans.
- AIO PUMP - A dedicated PWM/DC header for self-contained water-cooling setups.
Dual water-temperature headers and a flow-rate header feed information straight into the AI Suite utility, allowing you to track coolant temperatures and the flow rate of the entire loop.
- Water pump+ - A dedicated header can supply over 3 amps to high-performance PWM or DC water pumps.
- Water in/out - A dedicated header enables monitoring of temperatures at the input/output points of any component.
- Water flow - A dedicated header enables constant monitoring of flow rate throughout the entire loop.
OptimizationROG Crosshair VIII Dark Hero is packed with intuitive and flexible tools to allow customization across all system parameters to deliver the performance you want.
Performance Level Up
The dashboard-style control panel of AI Suite 3 lets you fine-tune almost every aspect of your ROG Crosshair VIII Dark Hero system with ease. Get the best balance between performance, cooling, stability, and efficiency via one simple and intuitive interface.
The renowned ROG UEFI (BIOS) provides everything you need to configure, tweak, and tune your rig. It offers intelligently simplified options for newcomers to PC DIY, as well as comprehensive features for seasoned veterans.
Accurate Voltage Monitoring
Conventional motherboards use single-ended sensing tapped from a location that isn't ideal, leading to a large disparity between the actual voltage fed to the CPU and the value reported to software. ROG Crosshair VIII Dark Hero features a differential-sensing circuit and delicate IC that simplify overclocking and tuning by allowing you to track voltages more accurately.
CONNECTIVITYROG Crosshair VIII Dark Hero offers advanced connectivity, including WiFi 6 (AX200) and dual Ethernet with Intel® 1Gb and Realtek 2.5Gb Ethernet port to eliminate bottlenecks so you can enjoy exceptionally smooth online and LAN play. Additionally, the M.2 supports AMD StoreMI technology to maximize the speed of your SSD for faster load times, and SupremeFX on-board audio provides superb sound, while saving a PCIe slot.
