I have been using gtx 570 on a 600 watt psu for like 6 months, however now my computer does not power up with gtx 570. It works fine when graphics card is removed. with card inserted only it's fan move a bit and nothing happens. But with gtx 570 inserted in board but not provided power(through 2x6 pin connectors) computer does start up.
what is the reason psu or graphics card???

Your power supply is not really a quality unit.
Your GTX 570 requires 550 watts. A decent 600 watt PSU would be working hard to power it after the power supply is 2-3 years old.

The problem with cheaper power supplies is that no one verifies the power rating, thus they can slap whatever power rating they want on the sticker. In reality most of them that say 600 watts could not sustain powering anything at 450 watts.

I would be willing to bet that if you put a quality psu in your system it will boot right up.
Since 550w is the recommended you should provide yourself a little more wiggle room then just 50 watts so I would look at a 650 watt psu.
You should look at Seasonic, XFX, EVGA, Antec, Corsair (HX, TX, RM series) or Rosewill...

You want something at least in Tier 2 class B or higher of this list:
