The HP EliteDesk 800 G9 Mini supports 13th Gen Intel on LGA 1700 — but not 12th

The HP EliteDesk 800 G9 Mini runs on LGA 1700 with 13th Gen Intel Core processors (Raptor Lake) — i3, i5, i7, and i9 — at 35W or 65W TDP. What makes this notable: it does not support 12th Gen or earlier CPUs. Unlike most LGA 1700 systems that offer backward compatibility across Alder Lake and Raptor Lake, HP locked this one to 13th Gen only. If you’re sourcing a used chip for a budget build, make sure it’s Raptor Lake — older CPUs won’t boot.
