Impact’s unusual Mini-DTX form factor is a deliberate choice. Many Mini-ITX cases ship with enough space for a dual-slot graphics card, meaning there’s typically unused space below the bottom PCIe® slot – space that could be utilized to mount more components or enable additional features. Being marginally taller than mini-ITX allows Impact to exploit this unused space, allowing ROG engineers to squeeze in features while still fitting a large proportion of mini- ITX PC cases.
We’ve fully exploited the extra space afforded by Impact’s Mini-DTX form factor to dedicate more space to the board's VRM and chipset cooling design.
ACTIVE VRM AND CHIPSET COMBO HEATSINK
Dual Custom Delta Superflo Fans:Â The custom low-noise fans feature a high-durability bearing with a 60,000-hour L10* lifespan.
Dual-Intake Fan Bracket: A unique brace design recesses the fans to enable reliable ventilation in tight spaces.
Finned Heatsink:Â The heatsink fin density is optimized to maximize surface area while maintaining a low-resistance exhaust path.
* L10 bearing lifespan specifies the minimum number of hours that 90% of the bearing are expected to last.
FULL-SIZED ALUMINUM BACKPLATE
A high-efficiency copper heatpipe channels heat away from the VRM to a full-size aluminum backplate, spreading heat quickly and evenly, compensating for limited airflow in smaller chassis.
POWER DESIGN
The monstrous compute power of multi-core processors necessitates a power circuit that rapidly responds to massive current swings. Featuring an array of 10 strategically paired power stages, the Impact's VRM is geared for any workload and all operating conditions.
18-Pin ProCool II Power connector
Offers higher endurance and longer lifespan by lowering impedance to prevent hotspots and connector failure. The new design includes upgrades to metal amour and solid pins for better dissipation.
2Power Stages Mosfets
The VRM is comprised of 8+2 TDA21472 power stages, each rated to handle 70 amps.
3Microfine alloy chokes
Each power stage is accompanied by a high-permeability alloy-core choke rated to handle 45 amps.
410K Japanese-made capacitors
Metallic capacitors Input and output filtering is provided by solid-polymer capacitors rated to last thousands of hours at high operating temperatures.
COOLER BY DESIGN

MEMORY
OPTIMEM III DDR4 4800+ MHZ (O.C.)
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 Impact with your favorite modules and maximize Ryzen 3000 throughput for applications that demand massive bandwidth, or balance infinity fabric and memory performance for a diverse range of workloads.
DOUBLE-CAPACITY DIMM SUPPORT
Crosshair VIII Impact features a unique memory-trace design that supports up to 32GB per slot for a total memory capacity of 64GB. With double-capacity UDIMM modules, the Impact delivers four-DIMM memory capacity in a compact, dual-DIMM design.
NETWORKING
1WIFI 6 (AX200)
ROG Crosshair VIII Impact comes with on-board Wi-Fi 6 (802.11ax) support, offering ultrafast networking speeds, improved network capacity and better performance in dense Wi-Fi environments for exceptional online gaming experiences with the convenience of a wireless connection.
2INTEL ETHERNET
ROG Crosshair VIII Impact features the latest Intel® Ethernet (I211-AT) ensuring data exchanges with your network and the outside world are fast and smooth. Intel LAN reduces CPU overhead and increases TCP and UDP throughput, keeping more processing power.​​
SupremeFX
ROG Crosshair VIII Impact’s SupremeFX audio features a dedicated card to limit signal interference, and packs the SupremeFX S1220 codec, ESS® ES9023P DAC and premium capacitors for enthusiast-grade audio performance.
Unique design allows the codec's impedance-sensing function to be ported to either the front or rea r headphone.
2S1220 CODEC
10 DAC channels, simultaneous 7.1 channel playback, independent 2.0-channel, multiple-stream stereo to front panel outputs.
3NICHICON CAPS
Fine-quality Japanese-made components that produce a warmer, natural sound with exceptional clarity and fidelity.
4ESS®ES9023P
The ESS® ES9023P digital-to-analog converter creates a perfect balance for top-tier audio clarity capable of 112db DNR /-94dB THD+N for superior front-panel output.
DUAL PCIE 4.0 M.2
Dual PCIe 4.0 M.2 slots support up to 2280 and provide NVMe SSD RAID support for an incredible performance boost. Create a RAID configuration with two PCIe 4.0 storage devices to enjoy the fastest data-transfer speeds on the 3rd Generation AMD Ryzen platform.
ROG SO-DIMM.2
ROG SO-DIMM.2 is an innovative expansion card that allows two PCIe® 4.0 M.2 drives to be connected via Impact’s SO-DIMM interface. You can then add metal heatsinks, helping to control thermals for maximum performance while elevating the aesthetics.
