Compatible iMac models

This 300 W power supply replaces the original ADP-300AF T or PA-1311-2A board in any 27 inch iMac identified as model A1419. It covers the full production span from Late 2012 through Mid 2017, including both standard and Retina 5K variants. The unit matches Apple part numbers 661-7886, 661-7170 and 661-03524.

Who should buy this

Repairers restoring a 27 inch iMac A1419 that has lost power or shows intermittent shutdowns will find a direct-fit replacement here. Builders working on smaller iMacs, newer Apple Silicon models or non-Apple all-in-ones cannot use this board. Buyers who need a higher wattage rating or a different form factor must look elsewhere.

Deciding specification

The critical match is the 300 W rating combined with the A1419 model designation printed on the original supply. If the existing board carries ADP-300AF T, PA-1311-2A or one of the listed 661 numbers, this unit will fit and power the system.
