Finally, what I understand from your rig is that you are not doing any high end graphics upgrade neither overclocking except addition of 2 cards wifi and TV tuner. So high amperage single +12 V rails PSUs like CX / VX / Silent etc. are really needed ?
Actually this rig can easily be powered by CM 350 Plus PSU , the new PSU launched by CM in India for entry level machines. It is @ INR 1750 with 2 years replacement warranty . ( I myself have set up a machine with 9600 GT and Athlon 620 )
My Suggestion is to go with Extreme Power Plus 500 Watt OEM unit @ INR 2600 . Other recommendations up to you budget .
CM 350 Plus @ INR 1750
Gigabyte Superb @ INR 2000
CM Extreme Power Plus 460 @ INR 2550
yeah initially my choice was CM extreme pow plus 460 ,heard some negative reviews and the fact that it is not a 460w,made me think again,So are these noise levels at +12V

The efficiency of corsairs is tempting me,so are the almost negligible noise levels. Has anyone seen any reviews on CM real power 460W apart from that one on
TE.
Look at the efficiency at 80% loads.This is what i'm looking at
AT 80% load

The 86% efficiency of vx450 is tempting and looks like premium I pay for it over others is covered within a few power bills

I started this thread as a noob in PSU's and now everything makes sense as why I should avoid generic PSU's. I used to wonder why my power bills kept on increasing and UPS back up went on decreasing when I had just a 400W generic PSU. I was always thinking about the 500 rupee PSU but never thought about higher power bills that I'm paying because of it for almost 1.5 yrs.Yeah as the reviewer said the money I spend over VX450 is recovered with an year of lesser power bills(I wish it would)
So right now VX450 is in my mind,given I am able to save 4K by that time or else I'm looking at CX400.
