Can anyone recommend a wattage amount for me? I OC my Core i5 750 CPU, have 16GB of RAM, GTX 570, case fans, 3 HDD's, SSD. I do plan on upgrading to Ivy (Core i7 )sometime next year, so I'd want it to be able to handle that. I'd also have interest in a SLI setup at some point. Would I need 1000W, 1200W, or even higher?
There aren't many psu's higher than 1200w , there are a few but not many and the reason for that is that you have to have a lot of power hungry components to go above 1200w. If you do plan on SLI with two 570's and the rest of your selections I would go with the 1200w because it does sound like you could be interested in adding further.
I have this very same psu and I like it , I do have three 580's , 24gb of ram , a 980X cpu and three 180gb SSD's and this powers all that and other things as well so you should have plenty of head room with this psu.
The option to go with any psu that you want is yours to make and some will say that you don't need 1200w and that could be true but if you are spending the money and it's your computer then you can do what ever you want. You could also put in a 1000w psu and that might be enough for your needs and still have room to spare for addons. If you want to go with a 1000w psu then you could consider this one.
Yes Corsair does make a good psu and they seem to be pretty popular. The bronze , silver , gold , platinum are all ratings of the psu. It is the power efficiency of the psu while under load as to how much of its rated power watts it can provide.

For 1 GTX 570 or any high end single GPU setup including GTX 580 and HD 7970, a quality 650W PSU such as Corsair AX 650W, Seasonic X 650W is enough to power your system.
For 2 GTX 570, a quality 850W PSU is needed (Corsair AX 850W or HX 850W or Seasonic X 850W or OCZ ZX 850W would be the top choices)
Hey guys, thanks for the great tips and recommendations. I decided to just get a Corsair 1200W. I figure I'm not really sure what I'll be doing with my system, so I want the flexibility of having plenty of power. It seems that pretty much everytime I got with something that is "good enough" I end up regretting it in the future or it causes me headaches. Or, that could just be me being ridiculous! Either way, the extra $80 didn't seem like a lot especially considering the 7 year warranty.
