Bottom Line

The right board specifically for a compact build, not a default pick otherwise. Pair it with a single-CCD gaming CPU like the 7800X3D or 9800X3D, not a power-hungry flagship, given the tighter cooling clearance ITX cases have.

Pros & Cons

βœ… Pros

  • Full PCIe 5.0 and current AM5 feature set in a genuinely compact footprint
  • WiFi 6E and 2.5G LAN built in, no separate networking card needed
  • Aura Sync RGB for lighting consistency with other ASUS components
  • Enables a real ITX gaming build with a full-size desktop GPU

❌ Cons

  • Price premium over an equivalent-tier ATX board
  • Single PCIe x16 slot: no room for expansion cards
  • VRM cooling is tighter in ITX cases; verify case airflow before pairing with a hot CPU

Best For

  • Small form factor gaming builds that still want a full desktop GPU
  • Desk setups or tight spaces where a full ATX tower doesn't fit
  • Not the pick for a dual-CCD flagship build: pair a single-CCD X3D chip instead

Performance & Real-World Usage

Mini-ITX boards fit the same CPU and GPU as full ATX, just packed into a fraction of the space, which is what actually makes a genuinely compact AM5 gaming build possible. The tradeoff is real: fewer expansion slots (one PCIe x16 slot instead of two or three), tighter VRM cooling clearance, and typically a real price premium over an equivalent-tier ATX board for the smaller engineering. 10+2 power stages is enough for a single-CCD X3D gaming chip; it isn't the board to pair with a power-hungry dual-CCD flagship in a case this size.

Pair with the Corsair SF750 SFX power supply for a genuinely compact build: both are engineered specifically to fit the smaller footprint an ITX case demands, rather than being full-size components squeezed in.

The real ITX tradeoff

A Mini-ITX board isn’t a worse board so much as a differently-optimized one: one PCIe x16 slot is enough for a GPU (which is the only card most gaming builds actually need), but zero room for a capture card, extra NIC, or additional storage controller later. If a build’s future upgrade path might need a second expansion card, a full ATX board is the safer choice even in a mid-tower case with room to spare.
