My personal favorites for PSUs are the Rosewell Capstone, most of the Seasonic units, Corsair AX line (expensive), OCZ ZX series (stay away from Modstream), the higher-end Antec PSUs are decent too. The whole 80 plus thing is a good indicator of overall quality too -- 80 Plus is the bottom, 80 Plus Bronze is next to the bottom. Once you start getting into 80 Plus Silver and Gold rated PSU, efficiency goes up, and more importantly, engineering and parts quality goes up substantially. You can't get a 90-92% efficient PSU using cheap 30 year old Chinese main land parts and designs.
Everything else looks good. 16 GB of RAM is still a bit overkill unless you're going to be running virtual machines or such. No games make use of > 8GB of RAM now or in the foreseeable future, console ports are keeping RAM consumption down over time. Two fast 4GB DIMMS in dual channel should be easy to come by and reasonably priced.
No, the 80+ Certification is not an indicator of quality. I can show you dozens of Bronze-rated PSUs that are "avoid at all costs" type of PSUs. I can even show you some Gold-rated PSUs that should be avoided, such as that RAIDMAX PSU he was looking at a few minutes ago.
The quality of PSUs should never be judged by the 80+ Certification. For many PSUs, it's just as useful as judging the quality by the name of the PSU, or by the color or something else like that. In other words, the 80+ Certification is mostly marketing hype.
