My PCU is 550 watt, has two 12v rails - one at 28 amps and the other at 20amps - and is +80 bronze.
Here is a link for all of the information:

Currently I am running a GTX 550 Ti that is overclocked. I have no problems whatsoever with the PSU. The 550 Ti has a TPD of 116 watts and 9.7 amps.
I am considering buying a gtx 770 and, logically, my psu should power it since it provides 40 amps on the 12v rail and plenty of watts. I also dont have much else in my system to use too much power.
GTX 770 - 230 watts and 19.2 amps.
Note that the power rating is based on the card's TPD and that I have no intention to overclock or reach the TPD.
So my questions are:
1. Can the GPU run? If not, why?
2. Do I have to worry about the dual rails? If so, how do I wire the GPU to ensure that it is receiving enough power?
3. This card requires an 8 pin connector. Can I buy a converter to convert 6 pin to 8 pin and does it matter which of the two 6 pins I convert?
4. I also have no idea how to tell which wires are on which rails so I don't know if I would be wiring it correctly of not.
Last note: I am running a i7 2600 CPU w/ 10% OC, GTX 550 Ti, 8 gb RAM, 1TB HD, Blu Ray, 2 case fans, 1 CPU fan, motherboard, and wired keyboard and mouse. I would estimate that it draws about 220 watts at full load.
Thank you for reading.
