Power-envelope constraint 65W chassis class
Intel rates the Core Ultra 7 265 for 65W base power and up to 182W turbo power, while ASRock limits the DeskMini B860 to 65W processors and supplies a 120W adapter. Sustained 265 performance therefore depends on the chassis BIOS limits and cooler rather than the processor's unrestricted desktop maximum.
