I have three, taken from 3x iMac Pro 2017’s. All were tested and fully working, guaranteed, by me personally. In all three cases they came from an iMac which had been meticulously tested and found faults that had nothing to do with these working power supplies. Please handle carefully, as they carry a hefty charge and shock if you are careless! I had one returned recently as the buyer wanted to see if it fixed his iMac. There was a problem with his GPU, so it didn’t fix it. Please only buy this if you are certain the issue is the power board. THESE ALL WORK.
