Your PSU isn't powerful enough on the 12v rails. It averages out at 15A each which is nowhere near enough for the GPU. The  total is according to the spec: Four +12V rails provides superior performance (combined loading of 62A). A single rail would have suited you better.

So the solution is to buy a new PSU with 1000W power?What do you think.Can you tell me for sure?Tnx for reply

Hey mate.I read it.So i think i must buy this one http://www.coolermaster.com/product.php?product_id=6628 What is your opinion?Is it enough for my GTX 590? Thanks

That PSU has a single 12v power rail at 80A so should be fine for your card. These dual GPU cards draw a lot of power and you also need to consider the drop in output as the PSU ages too.

Hi Dude,

I would say that PSU should work fine as long as you use the two rails from the 12v supply (50A for 12V3 & 12V4) they should be more than powerful enough.

[evaos]

M8 propably i do wrong.The PSU that i saw for buying is this one at last http://www.thermaltake.com/products-model.aspx?id=C_00001000 So this is ok for my GPU?Sorry again m8 and tnx a lot from the previous answer

[Dark Mantis]

It is similar but not quite as good as the other one but it should work fine as long as you use two different 12v rails to supply the GPU. That way you will be getting enough power to the card no matter what.
