How Much Power do I need to be covered?

I am almost to the point to start my new build, only thing left is to see if I'm gonna have enough power to run this baby without a glitch. The main knowledge I'm lacking is of Graphics cards, and that is the part that is leaving me uneasy about having enough power. I am going to list my important build specs that will pertain to this problem and I would appreciate if someone with the knowledge can tell me if my current power supply will do the job, even if I add more RAM and such.

That is more than enough. A 600W is the minimum but don't settle there a good extra power wouldn't hurt just to be more safe. Your +12v rail PSU is 69amp which is more than enough for that GTX570 which only needs 38amp

But that is only the GPU that needs that power, what about the 4 system hard drives, 2 storage, raid controller, etc. is that STILL enough power?

As said before 600w should be enough, but if you go for 750w you will have peace of mind. If you plan to add some ram or a hard drive, 750w will be no problem, even a good 600 or 650w will be good. But if you want to add a second graphic card, you might need more (if you plan on going with 2 gtx 570's) But for 2 570's 850watts or 900watts should be enough. You should go with one of the brands listed by saint19, they are all good. Note that some, not all corsairs are built by seasonic, and are great power supplies.
