More about which minimum
  1. Get corsair cx 500w or gs 600w whichever in budget.both are enough for gtx 660ti.
  2. & for gtx 660 does a cx430 or VP450 suffice

    Yes, either of those should be fine. A GTX 660 only needs a recommended 430w power supply and that assumes a lower quality model. Both of those models are quite good.

  4. Yes cx 430w will suffice gtx 660.
  5. will i be able to OC card & CPU
  6. Get the Antec VP550p 550 watt PSU am sure it is in your budget range and its very efficient PSU...and you will be able to OC both of card and CPU with it...
  7. Overclocking the answer is no.for overclocking you should get minimum 500-550w psu.
  8. personally i would not go lower than a 550w. but that is just me, i am more comfortable having some headroom for psu
  9. Yea I wouldn't go cheap on your power supply people will tell you what the power usage is on a unit and how your graphic card will only draw this amount of power from it but honestly if you are only going to spend 40-50 dollars on a power supply you should expect it to perform poorly. There are a couple of power supplies I would recommend to you that are quality and won't break the bank. The one component you should care most about you should put 80-100 dollars into your power supply. Talking about getting away with how much wattage you can have to power your graphic card is like a car running on empty lasting 50 miles.

    Thinking of that as it is is budget

  12. Corsair VS550 550 Watt PSU seems its the cheapest in india

    ^ The only correct part of this is to get a quality power supply. There is NO reason to spend $100 on a power supply when a $30 model is all you need. If you needed a high end power supply I would have recommended one.

    The GTX 660 is a low power card based on the 28nm manufacuring process.

    Note the following is total system power with a power hungry 6 core i7 3960X overclocked to 4.3Ghz. The most the whole system used was 287 watts. Since you should leave about 100-150 watts headroom when selecting a power supply my original recommendation of the 430CX or VP450 stands.

    As to overclocking. The GTX 660 is not an amazing overclocker like some previous generation cards were. The most Anandtech was able to draw with a 10% overclock was 307 watts. Remember this is still with an overclocked 6 core i7 3960X pulling way more power than your i5 750 ever could. So even with overclocking my original recommendation stands true.

  14. Pay attention to number one. I disagree with you. It's wise to invest in your power supply. We are never going to agree on this so I'll just agree to disagree with you.

  15. Beware of the current requirement too

    I read somewhere that the gtx660 and gtx660TI both demand a minimum of 24A from +12V as well as 450W from the PSU.

    I've seen many 500+ Watts PSU's on the market coming with only a meagre current of 20A at +12V. I can't say for sure if these are capable of powering the gtx660 as I have not tried them myself, but what I do know is I don't have the money for expensive firework tests. So yeah better safe than sorry I'd say
