Please contact our team to discuss GPU upgrade options, pricing and which GPU is best suited to your software.

Why is the CPU limited to 150W and does it slow the PC down?

The limit keeps performance steady rather than slowing it, because the Intel Core Ultra 9 285 is configured in BIOS to a sustained 150W TDP 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. A stable 150W limit gives 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.

What resolution is the 27″ screen?
