I am considering a 550w PSU for a new build. I originally settled on the Antec Earthwatts Gold Pro

because I built systems about 20 years ago and had great luck with Antec in general. But everyone raves about Seasonic, so I started looking at them, but I cannot tell the difference between the FOCUS Gold and G-series, other than the FOCUS has a 7-year warranty and the G has a 5-year, and the G-series has "FCC" and "RCM" listed under its Safety and EMC section. Now, as far as I can tell, FCC and RCM are regulatory compliance standards for the US and Australian markets, respectively, so I'm not really concerned that the FOCUS is dangerous because it may be lacking the FCC stamp. Or it could just be that whoever entered the information on their website, forgot to enter it.

G-series: https://pcpartpicker.com/product/DPCwrH/seasonic-power-supply-ssr550rm
So, is the only major difference the warranty period (and possibly the quality of the parts by implication)? They're both within the same price range.
