The recommended for a system with GTX770 is 575watts but since yours is 550watt and reasonable quality it will run it, here is actual power consumption, total system under load 383 watts http://www.anandtech.com/show/6994/nvidia-geforce-gtx-770-review/16

The Nvidia site recommends a 600 watt power supply. But, like rolli59 said the one you have is a decent power supply but it is cutting it close. If you could sell that it and get a better one, you will be better off. Once you start using close to 100% of a power supply you will have more heat dissipation.

Here is a pick of a 6 and 8 pin.
