There is nothing functionally different between any of the AX1200 PSUs. The only change is that a zip tie was replaced with adhesive because we found that a loose zip tie within the AX1200 could cause the ferrite core within the unit to vibrate and cause it to be louder than it should be. If your unit had this problem you would hear it, and we would be happy to replace it for you. Overall it was a small % of the first batch of these AX1200 units that ran into these problems, and any purchased within the last month or two should not have the problem.
