Hi,

I'm looking to replace my dying GTX 660 Ti with a GTX 770: http://www.overclockers.co.uk/showpr...odid=GX-202-MS

However, I am concerned that my current PSU (Antec 520w High Current Gamer) is not sufficient, so I will need a new one.

Can anyone recommend a good PSU for my rig?

1 Terabyte Hard Disk
Windows 7 Home Premium 64 Bit
Nvidia GeForce 2GB GTX660Ti
Intel i5 3570k
ASRock Z77 Pro3 Motherboard
8GB DDR3 1333Mhz Memory
Antec 520w High Current Gamer Power Supply

Thanks.
 
Your link did not work for me.
EVGA recommends 42a for the GTX770. Their recommendations are conservative to account for cheap units.
Your 520w psu is a good one, and can deliver 40a. It probably can do more than that.
I suspect that will be enough, so go ahead and try it.
If you encounter artifacts or other symptoms of insufficient power, then buy a stronger psu.

I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

I might suggest a 650-750w Seasonic unit that will handle any single graphics card out there, including a GTX690.
 
A 600W is a safe PSU good headroom and won't be spending the extra money for extra watts you system will never utilize while its good to always have more watts than you need 600 is more than enough for a 770 and a 780 Ti. I power a 770 Classified with an EVGA 600B and a 780 Classified with the same PSU. This psu cost me about $70
