i have two questions .
1) wich psu i should buy so that it can fullfill my demand when i will buy the new upcoming nvidia 560 or 570 card .
my budget is $180 also keep in mind that ONLY CORSAIR COOLERMASTER and ANTEC products are available in my country.
2) currently im using coolermaster 600w extreame psu will this one ok for new nvidia 500 series cards like 560 or 570 .should i buy a new one or not. this is my power supply
what do u say abt CORSAIR TX 750 watt (non modular) its easily available and cheap round abt $ 110 vx 550 is also available for $ 97 so not a huge price difference . also keep in mind im running 8 120mm led fans and one cpu cooler .
you cant really go wrong with any antec or corsair 600w model. Should be enough power for any mid-high range single gpu system. If that coolermaster psu is more than a couple years old, replace it. Its not known for quality
Try and avoid buying buy brand name alone. An owner of an Antec SG-850 for example might say that his PSU is as close as you can get to an affordable "State of the Art" PSU (assuming you agree that $250 is affordable) and he's be right ..... but buying an Antec Basiq or Neo series can get you nothing above a no-name brand.
I think it's safe to say that the 570 and 560 will draw less power than the 470 (227 watts) and 460-1GB (177 watts).
You could get away with less but the sweet spot for single GFX card PSU's is 650 watts. Extra power availability doesn't burn electricity and, if ya look at the curves, efficiency peaks at 50% load.

Note: Just because you see a brand name on this list, never make the assumption that their other lines are of matching quality. Silverstone for example has other models w/ 6.0 and 7.0 ratings.
NFS - Not For Sale / NLA = No Longer Available / OOS - Out of Stock
Now if ya thinking you might SLI that rig someday, best to buy the capability now. An 850 will handle twin 570's since it easily handles twin 470's. I built 3 SLI rigs with the 470 this week and the fans on the CP-850 hardly spin up under load. For comparison purposes, again , the list below contains performance ratings (10 scale) at jonnyguru.com / prices as per newegg on 02/21/2010 and. again, ones w/ double asterisks (**) made it onto silentpcreview.com's Editor's Choice List meaning they excelled at both electronic and acoustic performance:
If ya have a compatible Antec CPX form factor case, (P183, P193, 1200, DF series), the CP-850 is a no brainer. It matches the top of the line units from Corsair (HX Series) and Antec (SG-Series) in performance, is about 1/2 to 2/3 the price of the competition at 850 and is quieter than they are. If I was OC'ing and / or using SLI, I would limit myself to these choices.
If only using one card and not going too crazy w/ the OC'ing, I'd get the Corsair TX series or the Antec TP or EA series. I have seen some good reviews of the Cooler Master Real Power Pro (Different animal than the less well received "Silent Pro" series). Avoid the GX series as its performance rating was a 6.0 any jonny's. The UCP series and "Silent Pro M" series has some good reviews.
"Right about now I’d probably be contemplating an award such as Editors Choice or maybe Gamers Choice and an almost full-bars score. But unfortunately as I’ve already covered on the previous page, the XFX Black Edition 850w does have a a tendency to go ‘pop’ under certain load conditions. These conditions were of course outside specification during the "Max Load" tests where the unit was placed under a load approaching 1000W, but under no circumstances should a PSU of this quality fail in this manner simply because the load is too high. OCP (Over Current Protection) should kick in every time, saving both the PSU from failure and your hardware from being 'zapped'. For this reason alone the Black Edition 850w won't be walking away with any awards today, which is a great shame considering how well it performed in all other areas."
