Ok, first I just want to apologize since I know this has been asked before. I've done a fair amount of research (on these forums and elsewhere), and I am still a little confused. I am building my own pc for the first time (with some help from a friend), and just wanted to know what you guys thought..

I'm getting a GTX 260 vid card (http://www.microcenter.com/single_product_results.phtml?product_id=0312750) by BFG, which states the psu requirement is 525 watts with 36 amps on the 12v rail.

The power supply I bought is an OCZ fatality 550 w (http://www.newegg.com/Product/Product.aspx?Item=N82E16817341022, was on sale over the weekend and was cheaper than this price), which says 2 +12v with 25amps per.

It sounds like I meet the requirements, but is it too close? I am not planning on doing SLI, so I figured this was enough, but I am a little paranoid as this is my first system I'm building. The rest of the specs are:

gigabyte GA-X58A mobo
i7 930 processor
1 tb wd black hd
6 gigs g.skill 1600 ram
1 dvd optical drive

Should i not even bother and send back the psu for a 600+ watt? Or am I pretty safe (as long as no dual vid cards) for the time being? Any input is appreciated.

At stock clocks the power consumption of gtx 260 55nm edition is around 130-160w w/without overclocking. I know the rated wattage of the cpu and it is 130w at stock. Your psu is good enough for just one GTX260 with that board and cpu.
