Dang. I got them.
Bhai mere PSU kelia kuch Karo.
If you are getting Seasonic you don't need to worry about any problems with it at all. In such a case you can a Seasonic PSU from Newegg.com which imports components from the USA to India.
So you can go with fully modular PSU like this for a mere 5.5k

If you buy from Newegg you won't get any warranty unless you ship it back to Newegg for RMA.
You cannot even think of comparing a Seasonic S12II 520w with Antec VP550P because Seasonic is GOD of all PSUs.
