PSU is solid, I have traced it down to a motherboard problem. The mother of a board goes into a hybrid shutdown, no POST beep, so the way to make it work is to reboot immediately after the first boot up. After that it is solid. I am replacing the mother of a board either this weekend or next with an ASUS Crosshair VI Hero board. Gigabyte customer support sucks @ss, and they apparently don't care to even contact me after I filed a request for RMA.
Also on the PSU the EVGA site claims that I only need a 450-500 watt PSU for this build!
