what does it mean 80 Plus GOLD certification on psu ?

these psu class are good ?

Its efficiency. If you have a 100watts powersupply and its 80+ gold that means it will roughly take 120watts from the wall to deliver 100watts to the PC.

But the rating doesnt have to mean a psu is good. There are plenty of powersupplies with 80+ gold that are really bad. 

 

Always read a review before purchase.

If he says a PSU is good, buy it.

we have a pretty good pinned topic: http://linustechtips.com/main/topic/423141-80-plus-efficiency-and-what-it-really-means/

that kinda brings the breakdowns to an easier understanding of the spec.

The pinned thread about efficiency is on the main PSU's and cases subforum page and in my signature as well as what @airdeano linked. Breaks it down pretty nicely.
