Verdict

The ASUS Prime X299-Deluxe is a premium ATX motherboard designed for Intel LGA 2066 Core X-Series processors, featuring the X299 chipset with support for up to 128GB of quad-channel DDR4 memory at speeds exceeding 4133MHz (O.C.). Key characteristics include extensive connectivity such as dual Intel Gigabit LAN, ultra-fast 802.11ad (WiGig) Wi-Fi, and a bundled ThunderboltEX 3 card, alongside dual M.2 slots (one with a dedicated heatsink) and a U.2 port for high-speed storage. Main pros are its innovative LiveDash OLED system status display, 5-Way Optimization for intelligent automated tuning, and a robust 8-phase digital power design that ensures stability for high-core-count CPUs. However, notable cons include its high premium price point, a vertical M.2 slot orientation that some users find physically vulnerable, and reports from early reviews regarding inefficient VRM heatsink cooling under extreme overclocking loads.
