Psu for gtx 560ti with i5 2500k

It is enough but CM PSU's are hit and miss products, I suggest going with similar sized Antec, Corsair, Seasonic or even XFX or OCZ.

The minimum recomended for a GTX560ti is 500W with a minimum of 12V 30A rating, I would consider getting at least a 650W if you are intending on doing any overclocking of the GPU or CPU. The extra headroom would allow for other components also.

Yes a GX550 would be enough.But I would prefer corsair TX550 or xfx core edition 550.

I'm with rolli59's post.
An OZC ModX is a better budget option then a CM GX.

There is still enough extra headroom for overclocking and other purpose.CPU=100W,GPU=200W other components 100W.These psu can provide around 44A on 12v rails ,so headroom=12x44-100(cpu)-200(gpu)-100(other component)=128W.Which is more than enough.Also note that the Cpu and gpu wattage are greatly exaggerated and probably never use so much power even when overclocked.

i am not an over clocker so 600 will be enough or 550?

550watt would be plenty quality 500watt would even run your rig fine.

another thing i want to ask is why u guys dont prefer cooler master bcz in pakistan cooler master,antec,fire strom these 3 brands are avaliable so which one is best and in some shpos crossior is also avaliable

The cooler master GX series failed a few reviews, the bigger units would start going out of spec with too much noise on the 3.3 V rail once they hit about 70% load. I wouldn't run any of the GX series units over about 50% load, but the best choice is just to pick a different unit from the start that doesn't have that issue.
