Asus ROG (X570) Crosshair VIII Impact, AMD, AM4, Ryzen 3000, (Mini-DTX) SFF Gaming Motherboard with PCIe 4.0, On-Board WiFi 6 (802.11Ax), Intel LAN, SATA 6GB/s, USB 3.2 Gen 2, SO-DIMM.2 and Aura Sync

The Asus ROG Crosshair VIII Impact remains the gold standard for SFF AM4 builds, packing enthusiast-grade power into a unique Mini-DTX frame. Its standout feature is the SO-DIMM.2 riser card, which houses two PCIe 4.0 M.2 drives away from the motherboard's heat, coupled with a dedicated SupremeFX audio card that delivers class-leading sound for small-form-factor systems. Overclockers will appreciate the 8+2 teamed power stages and the inclusion of a POST code display and BIOS Flashback directly on the rear I/O—luxuries rarely seen in this size class.

The primary trade-off is the Mini-DTX form factor, which is 1-inch taller than standard Mini-ITX; while it fits most modern SFF cases designed for 2-slot GPUs, it may conflict with ultra-boutique "sandwich" style enclosures. Additionally, the dual active-cooling fans for the VRM and chipset can become audible under heavy sustained loads, and the premium price tag reflects its position as a flagship product.

Despite these factors, the Impact is a definitive "buy" for users who refuse to compromise on stability and overclocking headroom. If you are building a high-end Ryzen 5000 system in a compact chassis, the unrivaled power delivery and diagnostic tools justify the investment, ensuring you get ATX-level performance without the bulk.
