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 utilised 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: 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: 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 ALUMINIUM BACKPLATE
A high-efficiency copper heatpipe channels heat away from the VRM to a full-size aluminium 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.
