Hi [NAME]-ltcsystems.us,   N24MJ will not work, as it is a 12 Gen PSU which is only for T420. As for 2FR04, it is indeed compatible with T430.     
Good afternoon,I am looking for a compatible PSU for a  PowerEdge T430.  I have 2 PSU's new, one is a 0N24MJ (495W) and a 02FR04 (495W).   My research indicates these are both compatible, but I wanted to confirm before traveling on site.  The current PSU's are 495W, but I am unsure of the exact PSU model.  Will these work for a  PowerEdge T430?
