I have an Antec green watts 650w watt PSU currently running an i5-3570k OC to 4 ghz and GTX 570 OC with volt set to 1013. I'm planning on upgrading in the next 3- 5 months and was wondering if I need to upgrade my PSU to get a gtx 770 running.

Its probably OK. But it might be a good idea to get a new one asap.

I will not be OCing this one, well not until later demanding games arrive. My main concern is the AMP, the GTX 770 requires a minimum of 42 amps to run and my PSU only has 2 +12Vrails with 38amps on each. I've read some other forums and went to "tech-specific" websites that said a PSU with 38amps would suffice the GPU. But I'm not quite sure if that's the case, what do you guys think?

Thanks for the help! I'm probably going to get this PSU Cooler Master Extreme Power Plus 700W Power Supply or this one
Corsair HX650 650 Watt Power Supply. Both seems to have great reviews and from dependable manufacturers.
