PSU for GTX 460 Cyclone OC

[Galadh]

Greetings,
I am about to purchase the card mentioned above. My PC consists of Athlon II X4 630 2.8 GHz, 4GB RAM DDR2 800 MHz and obviously HDD and DVD Drive.
Models I am considering:

OCZ Stealthxstream 2 500W
OCZ Stealthxstream 2 600W
Corsair CX600 600W

I guess the latter is the best choice? Any suggestions?

Well, I believe those ones would be better indeed, but I forgot to mention my budget. The top is around OCZ Stealthxstream 2 600W /Corsair CX600 600W prices... There are some powerful enough for this cost, I reckon.

You didn't specify the model number of the Corsair CX600. There's the CMPSU-600CX that has recently been discontinued but the stock in the distribution channel is still being cleared out. It doesn't have 80 PLUS certification. There is the CMPSU-600CXV2 which is the latest model and is the replacement and it does have 80 PLUS certification.

The OCZ StealthXStream 2 600 W (OCZ600SXS2) would be my recommendation. Hardware Secrets Power Supply Review of this unit is available here:
