At the moment I use an AX1200i and haven't had any problems. I also have an AX1200 and a cooler master V1200. The cooler master is a seasonic build. However, I have some issue at home that keeps taking out my psu.
I've heard the AX1200i has ocp type stuff and you can disable it with the software. Also heard that shamino complains about them being too smart or something and prefers the older AX1200.
