Wow, I took a close up look at your new power supply. It looks like your dealer installed the AC breakers with a hammer and cold chisel. Also, the breakers are mounted a little crooked and they didn't install a blank cover on the empty breaker slot, plus they didn't even bother to list the circuit designations. I don't want to cause you any unnecessary grief but when I see craftsmanship like this I tend to be concerned about the wiring. You should probably make sure that all the wiring is tightened down correctly. Loose wires can cause lights to blink off and on, and can cause arcing at the connection. It's only a ten minute job, but you need someone who knows what they are doing.
