Why is the CPU limited to 150W and how does this help performance?

The Intel Core Ultra 9 285 is configured in BIOS to operate at a sustained 150W TDP — a deliberate engineering decision for the all-in-one form factor. An unconstrained processor may spike to much higher power levels briefly, but in a thermally constrained chassis this causes overheating followed by throttling to very low clock speeds, then a recovery cycle — producing inconsistent performance. By setting a stable 150W limit, the CPU delivers consistent, predictable performance throughout a full working day. The Thermalright AXP90-X47 low-profile cooler, rated to 160W, handles this load comfortably, maintaining stable temperatures and quiet operation without thermal compromise.

What is the display quality like on the 27″ screen?

The integrated 27″ display is Full HD (1920 × 1080 resolution) — a practical, comfortable resolution for productivity, document editing, web browsing, video conferencing, and professional applications at this screen size. Users who require higher pixel density for detailed image work or who work extensively with high-resolution assets may prefer to connect an external 1440p or 4K monitor via one of the three available display outputs (2 × DisplayPort, 1 × HDMI), using the internal screen as a secondary display for palettes, communications, or reference material.

Who is this PC best suited for?

This all-in-one is best suited to architects, engineers, and creative professionals who need the performance of a high-end desktop workstation in a space-efficient, single-unit form factor. It is ideal for office environments where desk space is limited, home office setups where a clean aesthetic matters, and any professional workflow that benefits from 24 CPU cores running consistently at high clock speeds. The GPU expansion slot makes it particularly well suited to professionals who currently rely on integrated graphics but anticipate needing GPU-accelerated rendering, simulation, or AI workloads in the near future.
