Hey guys, I just upgraded my computer recently and I'm stuck in a dilemma. I've bought everything for my computer so far except my graphics card. I have enough money to buy the GTX 570 ( http://www.newegg.com/Product/Product.aspx?Item=N82E16814130613 ), But I did some research and I wasn't sure if my PSU would be enough to power all of the components in the build if I went with the 570. The alternative to this card would be the GTX 560 Ti ( http://www.newegg.com/Product/Product.aspx?Item=N82E16814121425 ) But then I would be sacrificing some performance. I'm not sure what to do at the moment, was wondering if you guys can help me make an informed decision.

First off your PSU is a good one and I will power the 570 and it has the two six pin connecters. Now if you feel that it is to close then you could look at the GTX 560 Ti 448 core which is all most a 570.

You might be happy with it. It is something to think about you can do some reserch on it. Here is a link to it at newegg. All that is just food for thought. I do wish you the best of luck with either card you can't go wrong.

A 570 uses about 40 - 60 watts more than a 560 Ti.

I estimate that an OCZ 550 watt PSU can realistically produce about 40 amps on the 12 volt rails (can't read the label on newegg). That is enough for a 570, CPU, and the rest of a not too elaborate system.

I also estimate, that at peak power, your system will pull around 350 - 380 watts form the power supply.
