ASRock X299E-ITX/AC Mini ITX X299 Motherboard - High Performance Core

Our review of the ASRock X299E-ITX/AC explains why this compact X299 motherboard is aimed at enthusiasts who want Core X-series performance in a tiny mITX footprint. It is best for builders who need high-end CPU support, multiple storage options and modern connectivity while keeping a small case. The single biggest reason to consider this board is its unusual combination of an X299 chipset and mini ITX size, which lets users run powerful LGA2066 processors and up to 64GB DDR4 memory in a very small system without sacrificing key ports.

Key Features

• X299 chipset: Provides support for Intel Core X-series processors and high-thread-count workloads in a tiny motherboard format.
• Mini ITX size: Packs advanced desktop features into an mITX board so builders can create compact yet capable workstations or small form factor gaming rigs.
• 64GB DDR4 support: Allows dual-channel memory configurations up to 64GB for demanding multitasking and content creation tasks.
• PCIe and SATA connectivity: Offers PCIe lanes and SATA ports that enable multiple storage devices and discrete cards for expandability in a small build.
• USB 3.1 ports: Modern high-speed I/O makes attaching external drives and peripherals straightforward during heavy data transfers.
• 2T2R wireless: Integrated 2T2R wireless provides onboard Wi-Fi and Bluetooth for clean networking without add-on cards.

Who It's For

This board suits compact workstation builders, enthusiasts who want to run Intel Core X-series CPUs in a small case, and users who need a dense feature set including PCIe, SATA and USB 3.1 in mITX form. It is attractive for content creators and prosumers who prioritize compute power in limited space.

Those who should look elsewhere include budget system builders who do not need X299-class features or buyers who prefer full ATX boards with more PCIe slots and native M.2 slots for heavy multi-GPU or multi-NVMe storage configurations.

Pros & Cons

Pros

• Exceptional performance density by bringing an X299 chipset to a mini ITX board for high-end CPUs.
• Good memory capacity with support for up to 64GB DDR4, enabling demanding multitasking.
• Modern connectivity including USB 3.1 and onboard 2T2R wireless keeps external devices and networking straightforward.
• Multiple storage and expansion options with PCIe and SATA ports despite the small footprint.

Cons

• Mini ITX layout limits physical expansion, so multi-GPU or many add-in cards will be impractical.
• Advanced features and chipset come at a higher price than mainstream consumer motherboards.
