Power Supply DC voltages

Mac Mini M2 2023 (A2686). Unit shut down today & not able to restart. Suspect a bad power supply & have removed it, but not sure what voltages I should be seeing on the pins. On removal, I find it is p/n 614-00045 with 10 pins on the DC side, but no labels for pin #'s. I measure no voltage on the outer pins, but do see voltage across most of of the others. I did find a test for an older version that indicated 12V should be present on the outer pins, but not sure that applies to this version. Appreciate any insight on whether no voltage on the outer pins indicates a bad supply as I don't want to throw money at it if the supply is still OK.
