Gold rating has nothing to do with quality of PSU does it ? Purely how efficient it is
It us quite possible for a silver rated PSU being higher quality than a gold one
This is true yes.
For example Superflower PSU's are typically far higher quality than other brands.
Example being AX1200i from Corsair struggling to power three 290X cards, whereas the 1200W Superflower Platinum powered 4 without issue. So two same wattage PSU's but the Superflower when 8 Pack was testing them smashed the Corsair too pieces.
