Just because a unit is 80 Plus Gold certified does not mean that it is a high end design.
The primary capacitor is Japanese, the secondary capacitors are CapXon (not Japanese), see final paragraph on this page:http://www.hardwaresecrets.com/article/FSP-Aurum-Gold-700-Power-Supply-Review/1228/5
It is also a group regulated design.
In a lot of markets Aurums are almost always the cheapest 80 Plus Gold units you can buy.
When FSP re-entered the retail PSU market with the Aurums, it was all they sold, so had to give a positive impression with long warranties, it is definitely a positive that FSP decided to support their product so strongly. Again, just because Aurums (used to be) the highest end design that FSP sold doesn't mean that it is a high end design in comparison to other manufacturers/competitors.
