Requoting the original post that I've made:
So can we buy any power supply with 80 plus certification with our closed?
Absolutely NOT! You will still have to read reviews and see if the 80 plus certification holds any credibility in the real world tests. Do note that power supplies tested for getting this certification are tested on labs in a controlled environment. A possibility exists that in "real time" temps, humidity and conditions (some have dusty or "dry" environment) will give out very different results which can contradict with the 80 plus certification. Do also note that Ecos Consulting, the company giving out the 80 plus certifications, tests power supplies at a room temperature of only 23º C. If you have observed, many companies brag about running this power supply on operational temps of 40~50 degrees and put this certification label on the box inorder to make a quick sale. There have been majority of the scenarios that peers with limited technical knowledge and experience, without reading a proper unadulterated review give rave advices and recommend to buy a psu solely for the certification- unfortunately its these people who don't know the difference between lab environment and real world environment- let alone the difference between 23 degrees celcius and the labelled operational temps between 40~50 degrees mentioned on the bo these days. If this is the case, even power supplies with obsolete design can get 80 plus certification very easily.

I read the review of corsair vs 350 and everyone is saying that it is a bad psu (in Flipkart). Will it fry my computer components? I don't overclock my PC and don't do any type of gaming. I use my PC for running AutoCAD LT 2011 (lighter version of AutoCAD), VMware Player, Eagle PCB Design Software, Flash 8 (for cartoons), C Compiler & MS Office 2007. Some people are saying that corsair vs series develops humming sound, is it true? I was informed earlier in this forum that Corsair is playing musical chair with OEMs < How it will effect their product and what are the consequences of using those psus? I was also informed that vs series is low on quality < Will this fry PC Components?

at-least VS 350 is better than some desi generic PSUs so if you have bought any VS PSU from corsair there's nothing much you can do and there's not much to worry about either.

+1 Corsair PSUs are much better than most generic PSUs. Also I'd say read reviews on other sites than Flipkart. IMO reviews there are not too trustworthy.

You really need to get some facts right:
#1. Those power states are disabled by default irrespective of the motherboard brand.
#2. Most companies have released the list.
#3. If you've read few articles, the changes are only on the 12v rail, and processors aren't the only components that takes power from the 12V rail.

Allu Azad: In all honesty, Corsair has been constantly changing their OEMs/Rev numbers. Reliability and quality have been degrading, except in HX and AX non i series so far (not sure about the i series). So better off sticking with Seasonic S12II series.

You also need to look at the rev version and not just number. Reviewers don't get media samples whenever a newer rev comes out, so its hard to say.

Like that if you're saving, within the GX series there were 2 revs- which CM didn't bother to mention about the second rev which has bit better than the previous rev. It is only now they have GX II, of which I am not sure how good it is, same for thunder series. CM told me that they're sticking with enhance and seasonic oems only. Their V Series psu is made by Seasonic.

Corsair on the other is doing what CM used to do few years ago- and even worse. They have been changing OEMs after a particular period and have been known to degrade stuff. The "C" version of VX450 was known to be REALLY bad (something that overclock.net forum members highlighted), same for CX series. V2 came which turned out to be better but newer lots seem to be of different OEM and degraded capacitors. So far HX and AX are not messed around with... yet!

Long story made short, avoid Corsair as of now as they've decided to alienate their loyal userbase and its just a matter of time the shitstorm blows. Suffice to say Corsair is eventually going to have a 'Extreme Series' bashing session in any of the forums :p. Stick to Seasonic and their OEMS. Some of the Antec and coolermaster units use seasonic OEMs. For 450W units, stick with Antec VP450 and Seasonic S12II 430. 500w? S12II 520. GX series can be considered, but I am not sure about GX II series.

Only problem with Seasonic is Tirupathi enterprises. Some people have reported that they get bad service and late replies, but atleast in Mumbai I haven't heard anything. Considering that they're not dumb enough to mess/degrade their existing models, the chance to RMA Seasonic PSU is very less.
