Yes, that's a good PSU - the gold, platinum, etc., addresses it's efficiency at various load levels, not necessarily overall quality. There are plenty of golds on the market that I would pick over various platinum models. Raidmax sells a platinum that you couldn't pay me to use.
The numbers from the Anandtech chart you can take to the bank...for the specific chips that they tested. Your chip might do a lot better, as good, or worse than the CPUs they tested. Nothing over stock specs and ratings is guaranteed. My 4790K can do a higher clock, at much lower voltages and temps than their test chip did, while my 4770K can't do anything over the stock turbo speed.
1.3V is your safe voltage ceiling. Your CPU is always degrading as long...
