Hi, yeah the power adapter is universal, you will not have any problem whatsoever in using it in India, no transformers needed...but since it will be a flat pin u need an adapter to plug into power supply...you get this here or u can get one from there...they are cheap...
Since this will be a US PS3 the blu ray region code will be locked to "A". For games you don't have to worry since all PS3 games are region free, so you can purchase game disc in India.I purchased god of war 3, red dead redemption and F1 in Bangalore....all of them play without any problem in my HDTV....not sure about normal CRT TVs since the PS3 will be NTSC version...
currently there is no mod for Blu ray movies without jail breaks..so you can play ONLY region A blu ray movies (Asia is C and Europe is B), again this is not a major issue since most the blu ray you get in India are region free....or you can always order from amazon, i do that a lot...still works out cheaper than buying in India...
For me it really worked out better buying from US, Cheap and the ability to play region A blu rays as most (not all) of the blu rays in India is region free....
See if you can get the move bundle..this is what i got : PS3 Slim 320 GB + Move Bundle (1 motion controller, 1 PS Eye, Sports champ game , move demo disc) + Extra Dual shock controller + Move motion controller
Let me know if you need any more information...
