Difference between 80+ versions.

I was just surfing around but then i went curious for thus rating.
Basically, what i've heard is that the 80+ gold provides better power to the Computer. like if you are having a 650w PSU with a 80+ rating then youll have like around 640w to power the cpu but if you have a PSU with 80+ Bronze then it would just provide ~600w. Is that it ?
Is there any other difference.
I want to know is that if a person gets a 650w with a 80+ gold will it help in reducing bill as compared to a 80+ bronze.?

First of all forget about any significant power savings in this,they won't even cover the cost of a regular pizza in a month.More important than that is 80+ gold implies better quality components used which in turn means overall better psu.

So, a seasonic 620w will be same as RM 650 just non modular. no electrical savings there ?

just because both honda city & tata indigo are better than hyundai alto doesn't mean both are of same quality.seasonic is considered better than corsair by many.

Alright then A seasonic s12ii 620w will have take about the same units as a RM 650 ?

Get RM 650 as it's modular and will greatly help in clutterless cabinet. Avoid Seasonic for now ONLY due to after-sales service, as there are lots of complains around the web ( especially in India ) where RMA is a tug of war between us and company.

just making clear that 80+ gold may not always imply better quality components. for example corsair cs550m is semi modular 80+ gold certified but even contains caps from third tier companies. I would rather vouch for a psu with all japanese(especially from nippon chemicon) like seasonic s12ii 620 even though it is just bronze certified. no wonder why corsair put the warranty as just 3 years for the cs m models.
@op, read reviews before buy. Fancy numbers and features may not always count!

good info,i thought 80+ gold certification requires good quality components to achieve the power efficiency but seems like it is not always true.

Hmm thanks people
How would you compare RM650 components with s12ii 620 ?
but as Seasonic's RMA has gone changes what alternatives would you suggest ?

rm650 is also good.
