Crosshair VIII IMPACT
The ROG Crosshair VIII series heralds the arrival of Impact, the compact motherboard with colossal potential. Primped and primed for latest 3rd Gen AMD Ryzen CPUs, Crosshair VIII Impact's Mini-DTX frame packs loads of ATX-grade features, including advanced power delivery and cooling, dual M.2, next-gen Wi-Fi 6 (802.11ax) and onboard SupremeFX audio. It's the perfect choice for a small-form-factor gaming rig ready to rival full-size builds.
COMPACT DESIGN
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.


ROG Crosshair VIII Impact stacks up storage, audio and control features onto innovative vertical daughter boards, leaving us spare room onboard to add more connectivity and engineer features normally found on ATX boards into a small-form-factor (SFF) footprint.

Impact Control Card IV
Adds BIOS FlashBack™, Clr CMOS, Q-Code and FlexKey functionality.
SO-DIMM.2
Bundled expansion card with heatsink allows two M.2 drives to be connected via a SO-DIMM interface and helps control SSD thermals for maximum performance.
SupremeFX audio
A dedicated audio card housing S1220 codec and ESS® SABRE9023P for enthusiast-grade audio.
OPTIMAL PERFORMANCE
ROG Crosshair VIII Impact is equipped with an optimized power design and comprehensive cooling to exploit prodigious might of the latest AMD Ryzen processors without performance-zapping thermal throttling. It also packs innovations to double up on memory and push frequencies to the max.
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.
Robust power delivery starts at the component level. Every aspect of the ROG Crosshair VIII Impact's VRM is generously over-specified for the task.
